3-(Methacryloxy) propylmethyldiethoxysilane Description

3-Methacryloxypropyltriethoxysilane (CAS No. 65100-04-1) is a highly effective silane coupling agent designed for polyethylene and its copolymers, regardless of shape or density. It is ideal for applications requiring large processing tolerances, filled composites, and materials with high service temperatures, excellent pressure cracking resistance, abrasion resistance, and impact resistance.

This silane can be grafted onto the polymer main chain, enabling the modification of polymers like polyethylene. The grafted ester-functionalized side chains act as active sites for warm water crosslinking, enhancing the polymer’s performance in various industrial applications.

Package	5kg/drum, 20kg/ctn. Sealed and stored in a cool, dry and ventilated place, moisture-proof and water-proof, away from fire and heat source.
Usage	Used for glass fiber, it can effectively improve the adhesion between the mechanical properties (bending strength, tensile strength, etc.) of its glass fiber products and the matrix (a variety of resins, including thermosetting and thermoplastic, etc.). Used for copolymerization and grafting with acrylic resin on coatings. Used as a crosslinking agent for acrylic coatings, it can improve the weather resistance of acrylic coatings, prolong the service life, and increase the crosslinking density, so that the hardness of the coating film can reach more than 5H (pencil hardness). It can effectively improve the hydrophobicity of insulating oil; improve the mechanical properties of polyester concrete. Used as a post-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. Through polycondensation or copolymerization to form methacryloyloxy-containing silicone oil, this type of silicone oil can copolymerize with styrene, acrylic acid, acrylate, etc. by using methacryloyloxy radical reactivity to give acrylic resin and polystyrene resin With the characteristics of heat resistance, smoothness, and weather resistance. In the presence of a photosensitizer, it can be cross-linked and cured by ultraviolet light, and it has become one of the main varieties of silicone anti-adhesive release agents. As a reinforcing agent and crosslinking accelerator, it is widely used in composite materials, coatings, inks, glues, and sealing materials. It can also be used as resin modification additives and enzyme fixatives. As a cross-linking agent, it can be used for silane cross-linked polyethylene cables and pipes; in the wire and cable industry, use this coupling agent to treat the EPDM system filled with peroxide cross-linked by the coupling agent to improve the consumption factor and specific inductance and capacitive reactance. 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.
