The Uses of 3-Glycidoxypropyltrimethoxysilane
Pre-treatment of carbon steel with 3-(Glycidoxypropyl)trimet?hoxysilane enhances the dry and wet adhesion while reducing the cathotic disbondment rate of an epoxy coating
The Uses of 3-Glycidoxypropyltrimethoxysilane
(3-Glycidoxypropyl)trimethoxysilane is used in the production of carbon steel and its pre treatment favors the dry and wet adhesion of epoxy coating. It is also used to prepare epoxy-functionalized silica nanoparticles, which gives a reactive surface for one-step and high-density protein immobilization. It serves as a coupling agent and adhesion promoter.
What are the applications of Application
(3-Glycidyloxypropyl)trimethoxysilane is a Silane used in the manufacture of carbon steel
General Description
(3-Glycidyloxypropyl)trimethoxysilane (GPTMS) is a bifunctional organosilane with three methoxy groups on one side and an epoxy ring on the other. The methoxy groups bind well with glass substrates creating a 3D matrix. The epoxy group is reactive with amides, alcohols, thiols and acids. GPTMS is highly reactive in water and can be used as a linking agent between the surface of the silica and the polymeric matrix.
