ADDITION CURE SILICONE MOLDING RUBBER DESCRIPTION
        Our RTV-2 Molding materials are general called two-component room temperature vulcanization liquid silicone rubber with excellent fluidity and good operational performance. Add part B into part A, stir the mixture evenly, then pour or brush the liquid mixture to the mother mold, then after 2-6 hours, a flexible silicone rubber mold will be obtained a with resistance to deformation, high-temperature, acid and alkali and expansion.  


ADDITION CURE SILICONE MOLDING RUBBER INSTRUCTION
        If the customer wants to cast large size products with simple patterns , we should choose hard liquid silicone. On the contrary, if the mother mold is small size with fine details, we should choose soft rtv silicone.

ADDITION CURE SILICONE MOLDING RUBBER NOTICE
        1. In order to avoid no curing problem, it cannot mix with condensation cure silicone rubber, organic matter which is containing N, S, P organics and ionic compound like Sn, As,Hg, Ph. What’s more, please do not smoke when operating the food grade silicone rubber, otherwise, it will cause to no curing problem too.

        2, The solidification of platinum cure silicone rubber is particularly affected by temperature, higher the temperature is, faster the curing time will be.
