HOMEProducts > Roughened surface coating specification "Tack free"


Tack free

Tack free coating prevents adhesive material sticking.
We have also developed silicone transfer free product.

With high viscosity material or adhesive tape, "surface roughness" is effective which is designed to reduce the contact area. Our lineup includes non-silicone types and silicone types. Providing the materials needed, in the method needed, to the location where they are needed. Our reliable products are created through tireless research and development efforts, and state of the art facilities.



Even adhesive tape does not stick.

Use of a blade is possible even if wrapped.

Non-stick specification specialized for high viscosity adhesive material

High viscosity material like adhesive of tape may cause insufficient non-stick property on fluoropolymer coating with smooth surface. That case, point contact and surface treatment will have better non-stick (releasing) property.
Tack free coating is non-stick specification specialized for high viscosity adhesive and is focused on creating a surface for point contact, and makes the surface fine rough finish by thermal spraying and silicone or fluorine based coating is applied.


Comparison of silicone based and fluorine based coating

シリコン系タックフリー Problems caused by silicone transfer
(1) Lowering of adhesive strength (adhesive tape, etc.)
(2) Insufficient adhesion after vulcanization (probable cause for bursting due to lowered interlayer adhesive strength in tire rubber, etc.)



 
フッ素系タックフリー(FKシリーズ) Benefits of no silicone transfer
(1) Washable with polar solvent and reduction of cleaning time (except: silicone type)
(2) Fluorine based coating provides release property equivalent to silicone based coating (greatly improved release property compared to existing perfluoro types). Many other advantages can be found in addition to the above.
