Epoxy Silane Coupling Agent Crosile® 560 Glycidoxypropyltrimethoxysilane (GPTMS)

cas:2530-83-8

Glycidoxypropyltrimethoxysilane (GPTMS)

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.

Petrolium Resin C9 HT9140 Hydrocarbon Resin for Paints

Aromatic resins (C9 resins) are made from C9 hydrocarbon aromatics. Their composition depends on the hydrocarbon raw material (coal tar, crude oil). The softening points of these resins range over a wide range. Compared to C5 resins, they have a higher melt viscosity, are darker in color (dark yellow to brown) and have a higher softening point ranging from about 100 to 150°C. C9 resins are versatile resins that are compatible with many polymers.
