Joint Development of Low-Contamination Release Liners (Zero Adhesive Residue) | Balancing Functionality and Quality through Optimized Blending of Adhesives and Curing Agents

Release liners that suffer from poor compatibility with adhesives, leading to adhesive residue after peeling—we break through this physical property limit by optimizing the blend of adhesives and curing agents, combined with partnership with our partner manufacturers. Through a joint development scheme built on repeated prototyping and evaluation, we have simultaneously achieved enhanced functionality/performance and consistent quality. The Barrier of "Low-Contamination Requirements" Standing in the Way of New Product Tape Development Seeking to develop a release liner with zero adhesive residue for a new tape product, as existing products fail to meet low-contamination requirements.Poor compatibility with the adhesive results in trace amounts of residue remaining after peeling.●Situations where the issue manifests: New product development phase.●Primary impacts: Adhesion failures, peeling failures, and competitive pressure to switch to alternative suppliers' products. Why Zero Adhesive Residue Cannot Be Achieved: Poor Interfacial Compatibility Between the Adhesive and the Release Layer Physical property limits of existing liner materials. Poor compatibility at the interface between the adhesive and the release layer.●Basis for Identification: Product research and prototype evaluations. Countermeasures Attempted So Far and Their Limitations Changing the types of existing liners (only limited improvement), or adjusting the peeling force alone (contamination issue remained unresolved).Based on these limitations, we adopted the following approach as a more fundamental and drastic countermeasure. Solution Approach: Optimizing Adhesives & Curing Agents Blending × Joint Development Scheme Jointly optimizing the blending of adhesives and curing agents with the customer by proposing new materials + changing existing grades. STEP. 01 Material Proposal Proposing multiple release layer and adhesive candidates for low-contamination applications STEP. 02 Blending Optimization Reducing post-peeling contamination by modifying the curing agent ratio STEP. 03 Iterative Prototyping & Evaluation Conducting repeated evaluations on-site in collaboration with partner manufacturers Fujichemi Trading's Service Delivery Network: Head Office × Partner Manufacturers × Customers (Adhesive Evaluation) This solution is established through a clear division of roles across multiple locations.・Head Office / Domestic Sales: Project window (point of contact)・Partner Manufacturers: Supply of release layers, adhesives, and curing agents, along with technical expertise・Customer (Tape Manufacturer): Evaluation on the adhesive side●Supply System: Joint development scheme, supporting small-lot supply during the development phase. Results achieved through implementation Achieved enhanced functionality/performance, consistent quality, and a reduced defect rate.●KPI Candidates: Improvement in contamination test pass rates / Improvement in customer-side yield.●Implementation Lead Time: Mid-to-long term development project with repeated prototyping and evaluation. Anticipated Ripple Effects and Horizontal Expansion The implementation effects of this solution go beyond solving the primary issue. Please also leverage this as material for internal and executive-level proposals.・Commercializing the "combination proposal" of release layer × adhesive layer × curing agent・Establishing a strong presence as a bridge between adhesive manufacturers and film manufacturers Differences from Competitors: Why Fujichemi Trading is Chosen Adhesive manufacturers alone often find it difficult to commit deeply to the release layer side.

Temperature-Dependent Sheet HUMOFIT® | Reducing the Feeling of Pressure with F+BAND, a Fixation Band for Medical and Sports Applications

Balancing "rigidity at room temperature" and "flexibility at body temperature," which is difficult with conventional fixation materials—with F+BAND applying the temperature-dependent sheet HUMOFIT®, we have simultaneously achieved reduced tightness when worn and ensured breathability. This solution also looks toward horizontal expansion into the medical, sports, beauty, and wearable device fields. The Issue of "Tightness from Fixation Bands" Occurring in Medical and Sports Fields In medical and sports applications, there was a demand for a material that "fits the body without a feeling of pressure" as an alternative to fixation bands and bandages for arms. With existing materials, it is difficult to balance moldability and a snug fit.It was necessary to switch between hardness and softness depending on the situation, which was difficult to address with conventional fixation agents and tapes.● Scenarios where this becomes apparent: Improvement of existing products. Needs became apparent in situations such as exhibitions.● Main impacts: Discomfort when worn → lower continuous use rate, deterioration of workability in medical fields, and difficulty in differentiation from competitors. Why Existing Materials Do Not Fit: Physical Properties That Cannot Balance Room Temperature and Body Temperature The physical property limitations of existing fixation materials (plastics and rubber). They cannot balance rigidity at room temperature with flexibility at body temperature.● Grounds for identification: Interviews with existing clients and at exhibition booth displays. Countermeasures Attempted So Far and Their Limits Elastic rubber bands (feeling of tightness remains) and cast-type materials (heavy and difficult to handle).Based on these limitations, we adopted the following approach as a more fundamental solution. Solution Approach: HUMOFIT® Application × Die-Cut Shape Optimization × Perforating Process to Ensure Breathability Applying and developing the temperature-dependent sheet HUMOFIT®. Optimizing breathability and fit through material grade changes combined with die-cut shapes and perforating processes. STEP. 01 Material Grade Change Re-selecting the HUMOFIT® temperature-dependent sheet for medical applications STEP. 02 Die-Cut Shape and Size Adjustment Repeating evaluations with fixation band shapes STEP. 03 Perforating Process Ensuring breathability and suppressing stuffiness Fuji Chemi Trading's Supply System: Headquarters × Partner Manufacturers This solution is established through the division of roles among multiple bases:・Headquarters / Domestic Sales: Customer window and exhibition collaboration・Partner Manufacturers: Supply and physical property data of the HUMOFIT® sheet● Supply System: Prototyping response with multiple variations of shapes and sizes. Results of Implementation Achieved function and performance improvements. Tightness when worn has been reduced, improving the feeling of use in medical and sports fields.● KPI Candidates: Improvement in sensory evaluation of tightness / Extension of wearing time / Reduction of rashes and stuffiness at the wearing site.● Implementation Lead Time: Commercialized by repeating prototype evaluations of shapes and perforation layouts.

Thermal Barrier Paint Solution to Reduce Factory Electricity Bills in Thailand | Arranging Local Application Partners | Collaboration Across 3 Bases: China, Thailand, and Vietnam

In the Thai manufacturing industry, continuous increases in electricity rates and prolonged dry seasons have caused factory electricity bills—primarily for air conditioning—to squeeze profits. Focusing on the application of thermal barrier paint to roofs, we provide one-stop support ranging from electricity bill reduction simulations to the arrangement of local application partners and localized currency quoting. As a realistic solution to lower running costs with low investment and short construction periods, this has already been adopted by multiple Japanese factories. Soaring Electricity Bills in Thailand: What Was Happening Inside the Factories? Electricity rates in Thailand have undergone repeated increases due to fuel cost adjustments, making the pressure on production costs a chronic issue. Especially in factories with large roof areas, coupled with the prolonged high temperatures of the dry season, air conditioning systems run at full capacity constantly, inflating annual electricity bills to a level that demands executive-level management decisions. On the other hand, upgrading power reception and transformation equipment or installing solar power presents high hurdles regarding initial investment, construction periods, and the shutdown of existing facilities, leaving many facilities unable to take action."We want to lower our electricity bills. We also want to deliver results in the context of SDGs and CO2 reduction. However, we cannot commit to capital expenditure on equipment."——We hear these exact concerns from numerous Japanese factories operating local subsidiaries. Why Aren't Electricity Bills Dropping? Radiant Heat from the Roof Keeps Air Conditioning Running Constantly The root cause revealed through on-site inspections and roof surface temperature measurements is a structural issue: the roof and exterior walls lack heat-insulating performance, allowing radiant heat to flow directly into the interior. In some cases, the roof surface temperature exceeds 70°C during the day, and this heat warms up the ceiling space and indoor air, meaning the air conditioning cannot keep up no matter how much it cools.Furthermore, factory buildings in Southeast Asia often have outdated insulation specifications, so upgrading air conditioning units alone rarely provides a fundamental solution—this is the main reason why many hesitate when considering upgrading existing facilities.The basis for identifying this cause comes from cross-referencing the following two points:・Reviewing current electricity bill data provided by the customer・Measuring roof surface temperatures and checking roofing materials during on-site inspectionsBy matching these two datasets, we can conclude with near certainty that "heat inflow from the roof is the dominant factor." Countermeasures Attempted Thus Far and Their Limitations Countermeasures already attempted by many factories share the following common limitations:・ Adjusting HVAC operating hours: The effect is limited, and the system still faces high loads during production hours.・ Considering heat-insulating film application on the roof: Frequently abandoned due to hurdles in cost and construction periods.・ Considering retrofitting insulation materials to existing equipment: Requires halting existing equipment during construction, resulting in too great an impact on production.Given these limitations, thermal barrier paint emerges as the realistic solution—a move that "reduces heat inflow from the roof without stopping existing operations." Solution Approach: Thermal Barrier Paint × Electricity Bill Simulation × Local Application Partners By focusing on top-coating existing roofs with thermal barrier paint and providing the following three components as a complete package, we lower the hurdle for customers to make the decision to "give it a try." STEP. 01 Sourcing Alternative Materials and Replacements We perform a matrix comparison of both Japanese and local manufacturer products based on required performance, roof material compatibility, and cost to select the optimal thermal barrier paint grade. Focusing primarily on products with a proven track record in Thailand, we also obtain evaluation data from cooperating manufacturers as needed. STEP. 02 Presentation of Electricity Bill Reduction Simulations Based on current electricity bill data, HVAC operating hours, roof area, and insulation specifications, we will estimate the post-application electricity bill reduction effects and the payback period. Visualizing the "numbers" necessary for management decisions significantly accelerates the internal approval speed. STEP. 03 Selection of Local Construction Partners and Quotations in Local Currency Leveraging our Thai base as a starting point, we select reliable local application partners and optimize pricing and lead times via local currency quoting. We also propose process designs that minimize the impact on your production, including night/weekend application and split-phase application block by block. FUJICHEMI TRADING's Support Framework: A Powerful Triad of Japan HQ, Thai Base, and Cooperating Manufacturers This solution is realized through a clear division of roles among three parties: Japan HQ (Sales/Technical), our Thai base, and cooperating manufacturers.・ HQ (Sales/Technical): Selects coatings / Prepares electricity bill reduction simulations / Supports decision-making for adopting companies・ Thai Base (Local Subsidiary): Conducts on-site inspections, selects application partners, and provides local currency quoting/contracting / Manages application and construction / Provides after-sales support・ Cooperating Manufacturers: Supplies thermal barrier paint / Assists in grade selection / Provides evaluation data● Supply Framework: Local inventory support and small-lot application are available. This enables a small-start introduction where you can first test the effects on a single building before rolling it out across subsequent buildings. Results of Adoption: Simultaneously Achieving Running Cost Reductions and Workplace Environment Improvements We have received the following qualitative and quantitative result reports from adopting companies:・ Reduction in factory running costs (electricity bills): Achieved a reduction (▲) in electricity bills based on actual customer data.・ Lower indoor and roof surface temperatures: Stabilized summer production efficiency due to improvements in perceived temperature.・ Visualization of the payback period: Increased the precision of management decisions, accelerating subsequent rollout evaluations.・ Rollout track record: Cases exist where introduction to a single building led to expansion across additional buildings and sister factories.● Introduction Lead Time: Rapid turnaround is possible from the initial consultation through estimation to test painting. Anticipated Ripple Effects and Rollouts: 3 Returns Beyond Just Electricity Bill Reductions The effects of adopting thermal barrier paint extend far beyond electricity bill reductions. Please utilize these cascading ripple effects triggered by "heat mitigation" as supporting material for your internal proposals.1. Workplace Environment Improvement → Lower Turnover Rates and Higher ProductivityBy mitigating the extreme heat directly beneath the roof, the workload on workers during hot seasons is reduced. As securing and retaining operators is a pressing management issue in Thai manufacturing sites, improving the workplace environment directly links to lower turnover rates and enhanced productivity.2. Contribution to SDGs and CO2 Reduction ReportsElectricity bill reductions can be directly quantified as carbon emission reductions, leading to immediate score improvements in CSR and supplier evaluations. In an era where global headquarters' procurement standards closely scrutinize "suppliers' CO2 reduction track records," leaving behind quantitative data holds great value.3. Extending the Service Life of Rooftop EquipmentLowering the roof surface temperature reduces thermal stress on outdoor HVAC units and solar panel peripheral equipment, which can be expected to extend equipment life. This creates a double benefit: electricity bill savings combined with delaying future equipment replacement costs.Furthermore, for customers who establish a proven track record of introduction in Thailand, we can also support the horizontal rollout of identical proposals to your factory bases in Vietnam and China. Differences from Competitors: Why Choose FUJICHEMI TRADING? Compared to competitors that only sell coating products (paint manufacturers' direct sales and local chemical trading companies), our unique strength lies in our ability to provide a seamless, end-to-end service encompassing "electricity bill simulations + local application partner arrangements + local currency settlement." Our network, which bridges Japanese-level quality and localized cost structures, is the reason we continue to be chosen.・Difference from Manufacturers' Direct SalesThey do not provide simulations or arrange application partners, requiring customers to handle these arrangements individually.・Difference from Local Paint DistributorsWe offer selection based on Japanese quality standards, along with technical support in Japanese and proposal materials tailored for executive-level management. Product Information & Specifications Overview The main specifications of our proven thermal barrier paints offer a choice of multiple grades depending on the application and roofing materials. Typical specifications are as follows (please contact us for detailed specifications).

FAQ (Frequently Asked Questions) Are there any restrictions on the roofing materials? Our solutions support major roofing materials including metal, concrete, and slate roofs. Since the optimal grade varies depending on the material and shape, we will provide a proposal after an on-site inspection. What is the estimated payback period? It varies depending on the roof area, electricity cost rates, and HVAC operating hours. If you provide your current electricity bill data, we will run a simulation to calculate a specific payback period for you. Can the application be performed without stopping existing production? Yes. We will propose a process design that minimizes the impact on your production, including night application, weekend application, and split-phase application block by block. How can the effects be measured? Measurement is possible by comparing roof surface temperatures, indoor temperatures, and electricity bills. We also support you starting from the selection of representative measurement points. Is support available at overseas bases outside of Thailand? Yes, we can roll out identical solutions at our bases in Vietnam and China (Shanghai). For customers with multiple locations, we can also propose the standardization of specifications across all bases.
