Quick-drying lubricants
DRYSURF
After application, it dries instantly and forms a thin, uniform lubricating film.
DRYSURF, a quick-drying lubricant developed by Harves Co., Ltd., is widely used as a lubricant for the mechanisms of office automation equipment (personal computers, copiers, printers, faxes, etc.), audio-visual equipment (CDs, DVDs, video cameras, car audio, etc.), cameras, automotive parts, and other components.
Features of the quick-drying lubricants "DRYSURF"
- Wide range of application
Compared to grease, the product causes little running or staining, and is optimally used to increase lubricity or prevent noise on surfaces where grease cannot be applied. As it may be applied in thin layer, viscosity resistance can be kept low in precision sliding areas. - Excellent durability
It may be used for permanent lubrication, substituting conventional grease, with its uniform coating and high durability. - Highly safe
It is very safe for its non-inflammability and little odor. - Easiness of application
With its liquid form, the product helps shorten the work process with dipping and simplified coating. - Extensive product line
Custom-made products are also available for various usage / purpose.
Overview of the quick-drying lubricants "DRYSURF"
Lubricants - Semi-dry
This lubricant solves issues of grease such as controlling the amount of application scattering, running, sticking noise and stickiness. Despite the thin film, it has superior durability and low friction / wearing.
| Product name | Product type | Application |
|---|---|---|
| MDF-2400EL | General sliding parts | Machinery parts |
| TF-3500EL | General sliding parts | Smooth sliding and noise prevention of cup holders and air conditioner vent |
| MDF-1174S | General sliding parts | On shafts of lens unit |
| MDF-176EL | General sliding parts | Plastic sliding part of paper feeder |
| A-2048 | General sliding parts | Sliding part with heavy load |
| PL-1016EL | For contacts with low load | Contacts with low load |
| KD series | High durability grade | Metal gears on small motors |
* These are just a few examples and we have many more products available.
Lubricants - Completely dry lubricants
As the product forms completely dry film with no oil content, it has no possibility of sticking or oil contamination (dust collection, running, etc.). Upon application, it forms an oil-free, solid lubricant film. With no stickiness, it is optimal for use in places where oil is never allowed such as outer body, shutters of optical instruments, lens barriers, etc.
Water repelling / Oil repelling - Oil-resistant
Upon application, it forms an oil-repellent coating that prevents oil from entering in or leaking. Not only oil, but it also repels water and is also slightly moisture resistant.
| Product name | Product type | Application |
|---|---|---|
| OS-30P | Low concentration | Optical instruments (prevents exudation of grease from body tube) |
| OS-90P | Moderate concentration | Optical instruments (prevents exudation of grease from body tube) |
| OS-210P | High concentration | Optical instruments (prevents exudation of grease from body tube) |
* These are just a few examples and we have many more products available.
Dust prevention - Dust trap
Upon application, it forms a sticky layer that captures dust with particle size of few to tens of microns. It may be applied to prevent dust in body tube or around the image sensor of optical instruments.
| Product name | Product type | Application |
|---|---|---|
| DT-101 | Low concentration, Toluene free | Optical instruments (captures dust around image sensor) |
| DT-104EL | High concentration, Toluene free | Optical instruments (captures dust around image sensor and lens barrel) |
* These are just a few examples and we have many more products available.
