China Tin cure silicone factory tells you that the crosslinking agent XR-500 is a new type of silicone curing agent, which is an epoxy silane type crosslinking agent. It is mainly suitable for water-based systems containing carboxyl, amino, and hydroxyl groups.
China Tin cure silicone factory tells you that its reaction mechanism is that the epoxy group in the crosslinking agent reacts with the hydrophilic group carboxyl group, amino group, and hydroxyl group of the water-based resin; the alkoxy group reacts with water to form a silicon-oxygen bond through hydrolysis and condensation. Thereby greatly improving the adhesion and water resistance of the coating film to the substrate.
China Tin cure silicone factory tells you that this product is an environmentally friendly and non-toxic cross-linking agent. What is particularly surprising is that the water-based system added with XR-500 cross-linking agent has an unusually long service life, which can reach one year at room temperature, so Can be formulated into stable one-component coatings.
