Application:
Main application areas: glass fiber, adhesive, resin, filler.
Uses: KH-574 is suitable for polyethylene and copolymers of various complex shapes and all densities; suitable for larger processing technology tolerance, filled composite materials, etc., with higher use temperature and excellent resistance to pressure cracking , Abrasion resistance and impact resistance; can be grafted to the polymer main chain to modify other polymers such as polyethylene, so that the side chain carries the ester group of this product as an active point for warm water crosslinking. Used in glass fiber can effectively improve the mechanical properties (flexural strength, tensile strength, etc.) of its glass fiber products and the adhesion of the matrix (a variety of resins, including thermosetting and thermoplastic types, etc.). Used as an additive for inks and coatings, it can make inks and coatings have excellent film forming hardness and brightness; improve the adhesion of optical fiber coatings. As a reinforcing agent and cross-linking accelerator, it is widely used in composite materials, coatings, inks, glues, and sealing materials. It can also be used as a resin modification additive and enzyme fixative. As a cross-linking agent, it can be used in silane cross-linked polyethylene cables and pipes; in the wire and cable industry, the coupling agent is used to treat the clay-filled peroxide cross-linked EPDM system, which improves the consumption factor and specific inductance. Copolymerized with vinyl acetate and acrylic or methacrylic monomers, these polymers are widely used in coatings, adhesives and sealants to provide excellent adhesion and durability.
