Epoxy Silane Coupling Agent Crosile® 560 Glycidoxypropyltrimethoxysilane (GPTMS)
cas:2530-83-8
Chemical Properties
3-Glycidoxypropyltrimethoxysilane (GPTMS) Crosile® 560 is an epoxy functional silane that is a clear, pale-yellow liquid.
3-Glycidoxypropyltrimethoxysilane(GPTMS) Crosile® 560 is used as a coupling agent in polysulfide and polyurethane caulks and sealants, mineral-filled or glass-reinforced thermosets and thermoplastics, and glass roving adhesives. It is used in particular as a tackifier in aqueous systems, eg aqueous systems. Improves adhesion of acrylic latex sealants.

GPTMS Application
1. Crosile® 560 is a bifunctional silane possessing a reactive organic epoxide and hydrolysable inorganic methoxysilyl groups. The dual nature of its reactivity allows it to bind chemically to both inorganic materials (e.g. glass, metals, fillers) and organic polymers (e.g. thermoplastics, thermosets or elastomers) thus functioning as adhesion promoter, cross- linker, and/or surface modifier.
2. The use of Crosile® 560 as a coupling agent in mineral-filled plastics effectively enhances filler dispersibility, mitigates sedimentation, and significantly reduces resin viscosity while enabling higher filler loading and delivering notable improvements in water (vapor) resistance as well as acid and alkali resistance.
3. As a component of adhesives and sealants, Crosile® 560 improve both adhesion to the substrate and mechanical properties such as flexural strength, tensile strength and modulus of elasticity.
