Silane coupling agent CAS2530-83-8, also known as silane treatment agent; Primer. The general formula is Y (CH2) nSiX3, which is an organic silicon monomer with two or more different reaction groups in the molecule. It can undergo chemical bonding (coupling) with organic and inorganic materials, increasing the adhesion of the two materials. In the general formula, n is an integer from 0 to 3; X is a hydrolyzable group, such as chlorine, methoxy, ethoxy, acetyloxy, etc., which is easily hydrolyzed to form silanols and can react with inorganic substances to combine; Y is an organic functional group, such as vinyl, amino, epoxy, methacryloxy, thiol, etc., which can react with organic substances and bind.

Application
Mainly used in unsaturated polyester composite materials, it can improve the mechanical, electrical, and light transmittance properties of composite materials, especially greatly improving the wet performance of composite materials.

Soaking glass fibers with the coupling agent can improve the mechanical strength and electrical properties of glass fiber reinforced composite materials in the wet state.

In the wire and cable industry, using this coupling agent to treat the EPDM system filled with clay and cross-linked with peroxide improved the consumption factor and specific inductance capacitance.

Copolymerized with vinyl acetate and acrylic acid or methacrylic acid monomers, these polymers are widely used in coatings, adhesives, and sealants, providing excellent adhesion and durability.
