3-Methacryloxypropyltriethoxysilane Description

3-Methacryloxypropyltriethoxysilane is suitable for polyethylene and copolymers of various complex shapes and all densities; it is suitable for large processing tolerance, filled composites, etc., with high service temperature, excellent pressure cracking resistance, abrasion and impact resistance; it can be grafted to the main chain of the polymer so as to modify other polymers, such as polyethylene, so that the side chain carries an ester group with the product, which can serve as the active point of warm water cross-linking.

Synonyms	methacryloxypropyl triethoxysilane, 3-(triethoxysilyl)propyl methacrylate
Boiling point	112°C/5mmHg
Density	0.985±0.005 (ρ20)g/cm3
Refractive index	1.427±0.005 (n25D)
Applications	Glass Fiber \| Adhesives \| Resins \| Fillers
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 in glass fiber can effectively improve the mechanical properties (bending strength, tensile strength, etc.) of its glass fiber products and the adhesion of the substrate (a variety of resins, including thermosetting and thermoplastic, etc.). Used as additive after ink and coating, it can make ink and coating film have excellent film hardness and brightness; improve the adhesion of fiber optic coating. As reinforcing agent and cross-linking promoter, it is widely used in composite materials, coatings, inks, glues and sealing materials, etc. It can also be used as resin modification additive and enzyme fixing agent. As a crosslinking agent, it can be used in silane crosslinked polyethylene cables and tubes; in the wire and cable industry, the coupling agent is used to treat clay-filled, peroxide-crosslinked EPDM systems, which improves the consumption factor and specific inductance resistance. 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.

3-Methacryloxypropyltriethoxysilane: Guide

3-Methacryloxypropyltriethoxysilane is a kind of difunctional silane containing methacryloxy organic group and ethoxy silyl inorganic group. At the same time with organic reactivity and inorganic reactivity, it can react with organic thermosetting resin, and can also react with inorganic surface containing glass fiber, clay, quartz, other silica materials.

3-(Triethoxysilyl) proPYL methacrylate is a kind of chemical intermediate. Can make two kinds of materials coupling, improve the mechanical strength of products, composite material electrical properties, weather resistance and corrosion resistance, suitable for unsaturated polyester, acrylic adhesive.
