Instructions for Use
◇ Preparation: Before coating or impregnating, remove oil stains, dust, or existing treatment agents from the substrate (or fabric) surface; better results are achieved when used with a tackifying primer.
◇ Weighing: Weigh the appropriate mass of components A and B according to the ratio
◇ Mixing: Thoroughly mix the two components, being careful to scrape the bottom and side walls of the mixing container.
◇ Degassing: After thorough mixing, it can be left standing for a while to degas naturally, or vacuum rapid degassing can be used;
◇ Coating: Apply the degassed silicone rubber to the substrate surface; after coating, curing the product at high temperature can improve production efficiency.
