Description

Agrosil CAS NO 51570-32-2 is a high-purity organosilicon compound, specifically a silane coupling agent, known for its unique bifunctional reactivity. This product is essential for creating strong, durable bonds between inorganic materials and organic polymers, significantly enhancing composite performance. It is a critical raw material for manufacturers in the coatings, adhesives, sealants, and elastomers (CASE) industries, as well as for advanced material science applications requiring superior interfacial adhesion.

Application

• As a coupling agent in fiberglass-reinforced plastics and mineral-filled composites to improve mechanical strength and moisture resistance.
• A key component in the formulation of high-performance adhesives and sealants, enhancing bond strength to glass, metals, and masonry.
• Used as a surface modifier and crosslinking agent in silicone rubber and other specialty elastomers.
• Employed as an adhesion promoter in paints, coatings, and inks to ensure excellent substrate wetting and durability.
• Facilitates the treatment of fillers and pigments to improve dispersion and compatibility within polymer matrices.
• Applied in the production of moisture-curable systems and as a primer for various substrates.
