Description

2-(Acryloxyethoxy)Trimethylsilane is a bifunctional organosilicon monomer featuring both a polymerizable acrylate group and a hydrolyzable alkoxysilane group. This unique structure makes it a critical cross-linking agent and adhesion promoter in advanced material formulations. It is essential for manufacturers in the coatings, adhesives, and specialty polymer industries seeking to enhance product durability, weather resistance, and substrate bonding.

Application

• UV-Curable Coatings & Inks: Acts as a reactive diluent and cross-linker, improving film hardness, scratch resistance, and adhesion to difficult substrates like metals and plastics.
• Silicone Hybrid Polymers: Serves as a key monomer for synthesizing acrylate-functionalized silicones, used in release coatings, pressure-sensitive adhesives, and optical materials.
• Glass & Mineral Fiber Sizing: Functions as a coupling agent to improve the interfacial adhesion between inorganic fibers (e.g., glass, carbon) and organic polymer matrices in composites.
• Adhesion Promoters: Used in primers and direct-add formulations to enhance the bond strength of coatings and sealants on non-porous surfaces such as glass and metals.
• Surface Modification: Imparts permanent hydrophobicity, oleophobicity, or specific surface energy to materials via silane grafting technology.
• Dental & Medical Resins: Employed as a co-monomer in light-curable resin systems to modify mechanical properties and reduce polymerization shrinkage.
