Physical Indicators

CAS NO.: 59004-18-1 Density (25 ° C), g/cm3: 1.06 Boiling point: 214 ° C Flash point: 92 ° C Refractive index (nD20): 1.4135 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. This product can improve the mechanical and electrical properties of thermosetting and thermoplastic resins reinforced with glass fibers and containing inorganic fillers, especially those cured through reactive free radical mechanisms such as unsaturated polyester, polyurethane, and acrylate, peroxide vulcanized rubber (EPR, EPDM, silicone rubber, etc.), and thermoplastic resins (including polyolefin and thermoplastic polyurethane). 2. This product can significantly improve the dry and wet mechanical strength and electrical properties of unsaturated polyester composite materials filled with inorganic fillers, such as cast or die cast artificial quartz. 3. This product can be copolymerized with vinyl acetate, acrylic acid, or methacrylic acid monomers to synthesize silane modified polymers that can be crosslinked and cured at room temperature. These polymers are widely used in coatings, adhesives, and sealants, providing excellent adhesion and durability.
