Shin-Etsu KBM-603 (3-mercaptopropyltrimethoxysilane) is a thiol-functional coupling agent that enhances interfacial adhesion and reduces viscosity in polymer systems. Its reactive mercapto group enables covalent bonding with organic matrices, while methoxy groups ensure inorganic substrate compatibility. Ideal for coatings, adhesives, and composites, it improves mechanical strength, chemical resistance, and processing efficiency. The formulation supports fast curing at ambient temperatures and complies with REACH/RoHS standards
Dual Reactivity - Thiol group bonds with polymers; methoxy links to fillers/glass
Viscosity Control - Reduces system viscosity for easier processing
Durability Boost - Enhances UV/chemical resistance in harsh environments
Multi-Matrix Compatibility - Effective with epoxy, polyurethane, and acrylics
Sustainable Solution - Halogen-free, meeting global eco-standards
Rubber Compounding - Filler treatment for SBR/NBR to improve tensile strength
Electronic Encapsulants - Moisture-resistant sealing for circuit components
Marine Coatings - Corrosion protection for metal substrates
Adhesive Formulations - Enhanced bonding strength for structural applications
