Applications:
3-Glycidoxypropyltrimethoxysilane may improve dry and wet strength in cured composites reinforced with glass fiber rovings
Enhance wet electrical properties of epoxy-based encapsulate and packaging materials.
Eliminate the need for a separate primer in polysulfide and urethane sealants.
Improve adhesion in waterborne acrylic sealants and in urethane and epoxy coatings.
Application
It is mainly used in unsaturated polyester composites to improve the mechanical properties, electrical properties and light transmission properties of the composites, especially to improve their performance in wet environment.
In wire and cable industry, when used to treat EPDM system stuffed by pottery clay and crosslinked by peroxide, it can improve consumption factor and specific inductance captance.
Used for its copolymerization with monomers like vinyl acetate and acrylic acid or methacrylic, to form the polymers widely used in coatings, adhesives and sealants, providing excellent adhesion and durability.
Chemical Properties Colorless transparent liquid
Uses 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

3-Glycidoxypropyltrimethoxysilane Usage And Synthesis
Silane Coupling Agents KH-560 KH-560 is the first widely used coupling agent and has been used for 40 years. One end of its structure with reactive groups such as amino and vinyl, can react with epoxy, phenolic, polyester and other synthetic resin molecules. The other end is alkoxy (such as methoxy, ethoxy etc.) or chlorine atoms which is connected with silicon. These groups can be transformed into silanol in the hydrolysis in water solution or damp air. And the formed silanol is able to react with surface hydroxyl of glass, minerals and inorganic filler. Therefore, silane coupling agent is commonly used in silicate-filled epoxy, phenolic, polyester resin and other systems. In addition, it can also be used for FRP production, in order to improve its mechanical strength and resistance to wet environment. The organic groups of the silane coupling agent are selective about the reaction of the synthetic resin. Generally, these organic groups lack sufficient reactivity with synthetic resins such as polyethylene, polypropylene and polystyrene, and thus the coupling effect for them is poor. In recent years, new varieties of silane coupling agents with better coupling for polyolefins have been developed, but are limited in cost and other properties and are not yet widely used.
Silane coupling agent is also known as silane treatment agent. Its general formula is Y (CH2) nSiX3. Wherein n is an integer of 0 to 3; X is a hydrolyzable group such as chlorine, methoxy, ethoxy and acetoxy; Y is an organic functional group such as a vinyl, an amino, an epoxy group, a methacryloyloxy group and sulfydryl.
