γ-aminopropyltriethoxysilane

1. Resin: phenolic, urea-formaldehyde, furan, nylon, polyurethane, unsaturated polyester, alkyd resin, acrylic resin and natural rubber, styrene-butadiene rubber, neoprene rubber, nitrile rubber, EPDM rubber, PE, PP, PVC, SBS, etc.2. Fillers: talc, kaolin, mica, white carbon black, wollastonite, glass fiber, Al(OH)3, Mg(OH)2, metals and their oxides, etc.Product Features: 1. Widely used in composite materials to optimize the compatibility between polymers and inorganic substances in composite materials; significantly improve the tensile strength, bending resistance and other physical and mechanical properties of composite materials, as well as thermal properties, electrical properties, water resistance, etc. Especially suitable for various types of glass fiber reinforced thermoplastic and thermosetting resins such as: PP, PVC, PC, PA furan resin, epoxy resin, phenolic resin, polyurethane, polyimide, melamine resin. The usage amount of KH-550 at this time is: 0.2 The drying activation temperature after -1.0% treatment is 105-120℃. ​2.. This product can be used as a raw material for a new generation of bis-amino-modified silicone oil and a variety of silicone super soft finishing agents. The silicone oil modified by KH-550 treatment has greater affinity for fibers and can give various fibers super softness, smoothness, drape, antistatic, washability and anti-wrinkle effects. ​3. This product can improve the bonding strength by adding 1% or even less of the solid content to nitrile-phenolic structural adhesives, polyethylene butyraldehyde-phenolic adhesives, and polyurethane adhesive hot melt adhesives. 60% to 100%. Adding KH-550 to polyurethane sealants and plastic melt sealants can enable the sealants to achieve long-term adhesion to glass, masonry, metal and other substrates, and have excellent stability to weather and high elongation. ​4. This product can be used as an adhesion promoter in coatings and inks to improve adhesion, reduce curing temperature, and improve anti-corrosion properties. ​5. The use of this product in the foundry industry can reduce the amount of resin in silica sand, increase the strength of the mold sand (about 30%) and reduce the amount of gas. ​6. Using it in magnetic materials can improve the dispersion and adhesion of magnetic powder particles in plastic magnets and rubber magnets in organic matter, so that the magnetic particles have a higher orientation. In order to obtain better magnetic properties, improve the mechanical strength, weather resistance and easy dry processing of magnetic materials.Application effect example:Effect of KH-550 on the properties of phenolic resin FRP
