3-Glycidoxypropyltrimethoxysilane GPTMS Application

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.
The use of Crosile-560 as a coupling agent in mineral-filled plastics improves filler dispersibility, reduces its sedimentation tendency and greatly lowers the resin's viscosity. In addition, it leads to higher filler loading and a marked increase in water (vapor) resistance, as well as resistance to acids and bases.
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.
