Physical Indicators

CAS NO.: 13732-00-8 Density (20 ° C), g/cm3: 1.013 Boiling point: 239.2 ° C Flash point: 82 ° C Refractive index (nD25): 1.4310 Appearance: Colorless transparent liquid Solubility: Soluble in most aliphatic solvents such as aromatics and alcohols, ketones, etc. Slightly soluble in water, but prone to hydrolysis. The hydrolysate is unstable and prone to polymerization in the presence of overheating, light, and peroxides.


1. Used in unsaturated polyester composite materials: it can improve the mechanical properties, electrical properties, and light transmittance of the composite material, especially greatly improving the wet performance of the composite material. 2. Soaking glass fibers with the coupling agent can improve the mechanical strength and electrical properties of glass fiber reinforced composite materials in the wet state. 3. Application in the wire and cable industry: Using this coupling agent to treat the EPDM system filled with clay and cross-linked with peroxide can improve the consumption factor and specific inductance capacitance. 4. Copolymerized with vinyl acetate and acrylic or methacrylic monomers, these polymers are widely used in coatings, adhesives, and sealants, providing excellent adhesion and durability. 5. Acryloyloxysilane has higher activity than methacryloyloxysilane, which can better improve mechanical and electrical properties. 6. This product can be simultaneously involved in UV curing reactions, peroxide vulcanization reactions, hydrosilylation reactions, click reactions, and moisture crosslinking reactions.
