Main uses:
KH-151 is mainly used for polyethylene cross-linking; glass fiber surface treatment of unsaturated polyester, polyethylene, polypropylene resin and other glass fiber reinforced plastics: synthetic special coatings; adhesives; surface moisture protection of electronic components Treatment; surface treatment of inorganic silicon-containing fillers, etc.
KH-151 is an important cross-linking agent for cross-linked polyethylene. Compared with the common peroxide cross-linking and radiation cross-linking methods, the cross-linking process has simple equipment, less investment, easy control, and a wide range of polyethylene density. It is suitable for the production of fan-shaped wire cores and has the characteristics of high extrusion speed. Since silane cross-linked polyethylene (XLDPE) has excellent electrical properties, good heat resistance and stress cracking resistance, it has been widely used in the manufacture of wires, cable insulation, jacket materials and cross-linked polyethylene pipes.　　
KH-151 can be used for crosslinking of ethylene-vinyl acetate copolymer, chlorinated polyethylene, ethylene-propylene-ethyl acetate copolymer.
This product is also suitable for impregnating glass fiber and inorganic silicon-containing filler. Improve and improve the resin and glass fiber infiltration, adhesion performance, thereby effectively improving the mechanical strength and electrical properties of glass and plastic laminates. Wet mechanical strength and electrical properties. It also significantly improves the weather resistance, water resistance, and heat resistance of FRP and prolongs the service life of products. In addition, it also gives the product better electromagnetic wave transmission.
This product is copolymerized with a variety of monomers and can be made into special coatings. The coating has excellent electrical properties and moisture resistance. Anti-salt spray, anti-mildew three-proof performance. It is suitable for the protection of parts and components of cutting-edge defense products such as aerospace, radio flood control, radar, electronic components, and aircraft.
Used as a special rubber filler, it can improve its dispersion performance, thereby increasing the blending proportion of its filler and rubber and improving the tear strength of rubber. It can also improve the adhesion between rubber, metal and fabric.
It is used to prepare the sealant for plastic packaging materials of electrical components. In the 1, 2 polybutadiene plastic packaging materials, this product is used to treat the filler quartz powder to improve the three-way combination of the surface of the polybutadiene resin and the quartz powder and enhance the compactness of the plastic. Thereby improving the moisture resistance of the plastic packaging material.
It can be used for the surface moisture-proof treatment of electronic components, and can be used for the surface moisture-proof treatment of wafer-type fine-tuned ceramic dielectric capacitor anti-high voltage composite dielectric capacitors to improve the moisture resistance and surface finish of the product and improve the product qualification rate.
Used for surface treatment of the middle layer of composite glass, manufacturing aircraft windshield glass and other products, adding this product impregnated polymethacrylate film, bonding to the glass, to improve adhesion without cracking.
