Physical Indicators

CAS NO.: 23843-64-3 Density (20 ° C), g/cm3: 1.150 Boiling point: 220 ° C Flash point: 99 ° C Refractive index (nD25): 1.4610 Appearance: Colorless transparent liquid Solubility: Soluble in most aliphatic and aromatic solvents such as alcohols and ethers. When hydrolyzed in water, the hydrolysate will self polymerize.


1. Used as an additive or as a primer for coatings, inks, adhesives, and sealants such as phenolic, urea formaldehyde, furan, polyurethane, silicone, epoxy, phenolic, acrylic, etc., to improve the adhesion, corrosion resistance, weather resistance, water boiling resistance, and scrub resistance of resin coatings, extend service life, and improve the dispersibility and adhesion of pigments and fillers in the resin phase; 2. Used in resin grinding tools to improve the adhesion and water resistance between resin and abrasive, and to extend the service life of products; 3. This product can significantly improve the adhesive strength and sand strength of cold core box casting resin, reduce resin dosage and gas generation while maintaining sand strength, improve casting quality, and reduce scrap rate; 4. JH-A116 is suitable for inorganic materials such as glass, glass fiber, glass wool, mineral wool, mica, quartz and other siliceous materials, as well as metals and their oxides such as aluminum hydroxide, magnesium hydroxide, kaolin, talc powder, steel, zinc, aluminum, etc. However, it has little effect on fillers with no hydroxyl groups on the surface such as calcium carbonate, graphite, carbon black, and barium sulfate; 5. The polymers applicable to JH-A116 include (but are not limited to) phenolic, epoxy, furan, urea formaldehyde, melamine, polyurethane, acrylic acid, polyester, silicone, nitrile and other resins, as well as plastics such as nylon, PBT, PET, EVA, PP, PE, PVC, PVB, PVAC, PS, etc; 6. As a bonding promoter for alcohol based RTV silicone rubber, it can significantly improve its storage stability.
