Main Uses

   Silane coupling agent A-151 is mainly used for crosslinking of polyethylene; surface treatment of glass fiber reinforced plastics such as unsaturated polyester, polyethylene, polypropylene resin; synthesis of special coatings; adhesives; surface moisture-proof treatment of electronic components; surface treatment of inorganic silicon-containing fillers; and surface treatment of composite glass interlayer.

   Silane coupling agent A-151 can also be used for cross-linking of ethylene-vinyl acetate copolymer, chlorinated polyethylene, ethylene-acrylic acid-vinyl acetate copolymer.

   Silane coupling agent A-151 is used to impregnate glass fibers and inorganic silicon-containing fillers. It is also copolymerized with various monomers to prepare special coatings. Silane coupling agent!-151 is also used to treat special rubber fillers; silane coupling agent A-151 is used to prepare sealants for plastic sealing materials of electronic components; it can also be used as surface moisture-proof treatment of electronic components.

   Vinyl triethoxysilane is an important crosslinking agent for crosslinked polyethylene (PE) and is used for surface treatment of composite glass interlayer. Manufacture aircraft windshield and other products, add this product impregnated polybutyl methacrylate film, bond between the glass, improve the adhesion does not crack.

   This product is copolymerized with various monomers and can be made into special coatings. The coatings have excellent electrical properties, moisture and heat resistance, salt spray resistance and mildew resistance. It can be used as surface moisture-proof treatment for electronic components and surface moisture-proof treatment for anti-high voltage composite dielectric capacitors of circular fine-tuned ceramic dielectric capacitors, so as to improve the moisture-proof performance and surface smoothness of products and improve the qualified rate of products.
