3-Isocyanatopropyltriethoxysilane
As a premier silane coupling agent, 3-Isocyanatopropyltriethoxysilane (CAS 24801-88-5) is instrumental in enhancing the performance and durability of advanced materials. Its unique bifunctional nature, combining an isocyanate group with hydrolyzable ethoxy groups, allows it to bridge inorganic and organic materials, leading to significantly improved adhesion and mechanical properties in various applications.
- Achieve superior adhesion to inorganic substrates like glass and metal, leveraging its role as an adhesion promoter for silicone sealants and coatings.
- Enhance the bonding performance in reactive polyurethane systems, acting as a key adhesive promoter for both single-component moisture-cured and two-component reactive systems.
- Experience improved thermal, chemical, and UV stability, a critical benefit when used as a crosslinking agent for moisture-cured systems.
- Modify organic polymers for enhanced properties, contributing to the development of high-performance composites.
