Silmade® Low Friction – Silicone Surfaces 

Requirements

Silicone rubber is used in many applications because of its advantageous properties such as high elasticity or resistance to high and low temperatures. However the material’s high coefficients of friction (COF) often cause problems. Existing top coatings with low COFs have the disadvantage of low flexibility, i.e. the elasticity of the silicone rubber would be decreased too much. Other coatings have poor adhesion and abrasion properties. 

Solution

Silcos solved the problem by applying its Silmade® Low- Friction Coating. This polyurethane based top coat has low friction properties and is highly flexible to maintain the elasticity of the silicone rubber. Very good adhesion properties can be obtained between the top coat and the silicone rubber surface due to Silcos’ special surface pretreatment. The Silmade® Low-Friction Coating is available for both moulded and extruded parts.
