Description

Bis[3-(Trimethoxysilyl)Propyl]Ethylene Diamine is a high-purity, bifunctional organosilane coupling agent containing both primary amine and alkoxysilane groups. This unique structure provides excellent adhesion promotion and surface modification capabilities, enabling strong bonding between inorganic substrates and organic polymers. It is essential for manufacturers in the adhesives, sealants, coatings, and advanced composite materials industries seeking to enhance mechanical properties, durability, and chemical resistance in their formulations.

Application

• Adhesion Promoter: Key component in primers and adhesives for bonding glass, metals, and minerals to rubber, epoxy, and polyurethane matrices.
• Surface Modifier: Used to treat fillers like silica, glass fibers, and minerals to improve compatibility and dispersion within polymer systems.
• Crosslinking Agent: Functions as a co-curing agent and crosslinker in silicone and other polymer networks to enhance thermal and mechanical performance.
• Water-based System Stabilizer: Improves the stability and performance of aqueous adhesive and coating formulations.
• Fiberglass Sizing: A critical ingredient in fiberglass sizing formulations to improve the resin-fiber interface in composite materials.
• Mineral-filled Composites: Enhances the interfacial bonding in talc, clay, or calcium carbonate-filled plastics and elastomers.
