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, IOTA-2271 is the surface layer, with excellent release effect; IOTA-2440-1 is the intermediate layer, providing better strength and flexibility for the product; IOTA-2430-1 is the bottom layer, which has a certain adhesion with the cloth.
