Release liners that suffer from poor compatibility with adhesives, leading to adhesive residue after peeling\u2014we 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.<\/p>\n\n\n\n
Seeking to develop a release liner with zero adhesive residue for a new tape product, as existing products fail to meet low-contamination requirements. Physical property limits of existing liner materials. Poor compatibility at the interface between the adhesive and the release layer. Changing the types of existing liners (only limited improvement), or adjusting the peeling force alone (contamination issue remained unresolved). Jointly optimizing the blending of adhesives and curing agents with the customer by proposing new materials + changing existing grades.<\/p>\n\n\n\n STEP. 01<\/p>\n\n\n\n Proposing multiple release layer and adhesive candidates for low-contamination applications<\/p>\n<\/div><\/div>\n\n\n\n STEP. 02<\/p>\n\n\n\n Reducing post-peeling contamination by modifying the curing agent ratio<\/p>\n<\/div><\/div>\n\n\n\n STEP. 03<\/p>\n\n\n\n Conducting repeated evaluations on-site in collaboration with partner manufacturers<\/p>\n<\/div><\/div>\n<\/div><\/div>\n\n\n\n This solution is established through a clear division of roles across multiple locations. Achieved enhanced functionality\/performance, consistent quality, and a reduced defect rate. The implementation effects of this solution go beyond solving the primary issue. Please also leverage this as material for internal and executive-level proposals. Adhesive manufacturers alone often find it difficult to commit deeply to the release layer side. As a trading company capable of cross-functionally handling “release layers \u00d7 adhesives \u00d7 curing agents,” Fujichemi can fulfill the role of a collaborative hub.<\/p>\n\n\n\n The main specifications of our proven products can be selected from multiple grades depending on your application and requirements. The representative specifications are as follows (please contact us for detailed specifications).<\/p>\n\n\n\n
