3-Methacryloxy propyltriisopropoxysilane Description

3-Methacryloxypropyltriisopropoxysilane (CAS No. 80750-05-6) is a functional silane monomer containing methacryloxy groups, ideal for use as a crosslinking agent in pure acrylic emulsions. This silane easily copolymerizes into the main chain of acrylic emulsions, enhancing durability and adhesion in coatings applications.

The unique structure of CAS No. 80750-05-6 silane ensures excellent stability in emulsions, preventing premature reactions or crosslinking. Once the coating coalesces, the silane reacts effectively, ensuring the stability of waterborne coatings for up to one year of aging without losing performance.

Usage	1.CAS 80750-05-6 is isopropoxy silane, hydrolytic stability is better than conventional methoxy or ethoxysilane, suitable for occasions with higher requirements for storage stability. It can improve the wet and dry mechanical properties of polyester-based composites filled with fillers such as silica, glass, silicates and metal oxides. It improves the wet electrical properties of many inorganic mineral-filled composites such as cross-linked vinyl and polyvinyl chloride. It can be copolymerized with vinyl acetate and acrylate or methacrylate monomers to make wet-curing methylsilylated polymers. These methylsilylated polymers are widely used in coatings, adhesives and sealants to provide excellent adhesion and weatherability.

3-Methacryloxy propyltriisopropoxysilane: Guide

3-Methacryloxypropyltriisopropoxysilane is a functional silane with a methacryloxy group and three hydrolyzable isopropoxy groups, offering dual reactivity. This unique structure enhances the mechanical properties of resin-based composites and improves adhesion strength and water resistance in resin coatings.

The silane promotes bi-directional chemical reactions, improving bonding, adhesion, and compatibility between inorganic materials (glass, metal, fillers) and organic polymers (thermosetting resins, plastics, elastomers). This results in stronger resin matrix composites and enhanced adhesive performance for coatings.
