γ-Methacryloxypropyltrimethoxysilan (LT-570)
Class： Coupling agent series
CAS NO： 2530-85-0
Structural formula:
Descr1ption:
LT-570 is a bifunctional silane possessing a methacrylic organofunctional group and a tri- mehoxysilyl inorganic group. The dual nature of its reactivity allows it to bind chemically to both inorganic materials (e.g. glass, silica) and organic thermoset resins thus functioning as adhesion promoter, co-monomer for polymer synthesis, crosslinker, and surface modifier.
LT-570 is a clear, colorless, light and heat sensitive liquid with a characteristically sweet odor. It is soluble in alcohols, and aliphatic or aromatic hydrocarbons.
