Application

SF-YQ25 is mainly used to treat the surface of inorganic, organic and metal materials, giving them good adhesion to different materials, so as to improve the comprehensive performance of materials or products.

SF-YQ25 can react with amine, hydrogen azide and phosphate ester to obtain silane coupling agent containing urea group, azide group and phosphate group.

SF-YQ25 can be used as room temperature vulcanized silicone rubber adhesive to improve the bonding strength of the compound to the substrate.

SF-YQ25 can be used as an organic polymer modifier to achieve chemical modification. SF-YQ25 can also be used as a crosslinking agent and tackifying agent for paint.
