Liquid silicone rubber for silicone leather

    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.

    Usage

    1) Mixing ratio: 1:1 weight mixing and remove the air bubble.

    2) Curing Condition: coated liquid silicone rubber under high temperature, it will cure quickly. The curing time depends on the thickness and curing temperature used.

    3) Operation time:After mixing components A and B, the validity period of the mixture at 25 ° C is 48 hours.


    Clean

    Most hydrocarbon solvents can remove uncured silicon. Polar solvents, such as ketone and ethanol, cannot be removed.
