Description

3-Acrylamidopropyltrimethoxysilane, Tech-95 is a bifunctional organosilane coupling agent featuring both a polymerizable acrylamide group and hydrolyzable trimethoxysilane groups. This dual functionality makes it a critical component for creating strong, durable bonds between organic polymers and inorganic substrates. It is essential for manufacturers in the composites, adhesives, coatings, and sealants industries seeking to enhance material performance, adhesion, and moisture resistance in their final products.

Application

• As a key adhesion promoter in fiberglass-reinforced composites and mineral-filled plastics.
• To improve the bonding and durability of acrylic-based adhesives, sealants, and coatings on glass, metal, or mineral surfaces.
• As a surface modifying agent for silica, glass fibers, and other inorganic fillers to enhance compatibility with polymer matrices.
• In the formulation of moisture-curable acrylic hybrid resins and oligomers for advanced material science applications.
• For crosslinking and property modification in specialty silicone-acrylic copolymer systems.
• In the production of primers and treatment solutions for automotive, construction, and aerospace applications.
