Siwin is a leading manufacturer and supplier of organosilanes for over 15 years.

Epoxy silanes possess two functional groups, namely epoxy and alkoxy groups (hydrolyzable groups). The hydrolyzable groups (methoxy or ethoxy) first hydrolyze with the absence of moisture to form silanol. Due to the instability of silanol, it readily combines with the hydroxyl groups (-OH) on the surface of inorganics or metals through dehydration, thereby bonding with inorganics or metals. The epoxy group (organic functional group) reacts with various polymers, thus tightly combining two materials with completely different properties through chemical bonds.

Siwin epoxy silanes offer the good adhesion ability and at the same time will not cause yellowing.

Siwin epoxy silanes are widely used in marine coatings, metal coatings, automotive coatings, and

industrial anti-corrosive coatings to increase the adhesion and anti-corrosive performance of

coatings.  

Siwin epoxy silane oligomer is developed for water-based costings and formula for eco-friendly requirement of costing industry.

Siwin epoxy silanes can improve the adhesion between epoxy resin and substrate, improve the

electrical properties of epoxy resin electronic materials, potting materials, and printed circuit

boards, especially wet electrical properties. It is mainly used in unsaturated polyester composite materials, which can improve the mechanical properties, electrical properties, and light transmission properties of the compositematerials, especially the wet performance of the composite materials.  

Wetting treatment of glass fiber (with this coupling agent) can improve the wet mechanical

strength and electrical properties of the glass fiber reinforced composite material.  

In the wire and cable industry, Siwin epoxy silane is used to treat the clay-filled

peroxide-crosslinked EPDM system, which improves the consumption factor and the specific

inductance.

Siwin epoxy silanes copolymerize with vinyl acetate and acrylic acid or methacrylic monomers, which are widely used in coatings, adhesives and sealants to provide excellent adhesion and durability and chemical resistance.
