Flexible Coating Liquid Silicone Rubber
Two component 1:1 mixing ratio, coated liquid silicone rubber
Description
The coated liquid silicone rubber is composed of three products, MY-2271 is the surface layer, with excellent release effect; MY-2440-1 is the intermediate layer,
providing better strength and flexibility for the product; MY-2430-1 is the
bottom layer, which has a certain adhesion with the cloth.
