Description

n-(3-Acryloxy-2-Hydroxypropyl)-3-Aminopropyltriethoxysilane is a high-performance, multi-functional organosilane coupling agent designed to create robust chemical bridges between inorganic substrates and organic polymer matrices. Its unique molecular structure, featuring both acrylate and alkoxysilane groups, is critical for enhancing adhesion, mechanical strength, and durability in composite materials. This product is essential for formulators and manufacturers in the advanced composites, coatings, adhesives, and sealants industries seeking to solve interfacial bonding challenges.

Application

• As a coupling agent and adhesion promoter in fiber-reinforced polymer (FRP) composites, including glass and carbon fiber composites.
• Surface modification of mineral fillers (e.g., silica, alumina, clay) to improve dispersion and compatibility in polymer resins.
• Enhancing the adhesion of acrylic-based coatings, inks, and adhesives to difficult-to-bond substrates like metals, glass, and treated plastics.
• Formulation of moisture-curable systems and crosslinking agents for silicone-modified organic polymers.
• Improving the performance and weatherability of sealants and encapsulants in construction and electronics.
• Used in the preparation of sized glass fibers to protect filaments and promote resin bonding.
• As a reactive intermediate for the synthesis of specialty silane-modified polymers and oligomers.
