Physical Indicators

CAS NO: 2602-34-8 Product appearance: colorless transparent liquid Solubility: Soluble in most organic solvents, hydrolyzed in water Boiling point: 270 ° C Density (20 ℃): 1.004 ± 0.005 Flash point (closed cup): 125 ℃


1. Used in adhesives to increase bonding performance, it is suitable for resins such as epoxy, phenolic, melamine, polysulfide polyurethane, polystyrene, etc. 2. Improve the adhesion of inorganic fillers, substrates, and resins, thereby improving the mechanical strength and electrical properties of composite materials, and having a high retention rate in the wet state. As an inorganic filler surface treatment agent, it is widely used in clay, glass microspheres, talc powder, wollastonite, white carbon black, quartz, aluminum powder, and iron powder. 3. This product is suitable for epoxy sealants filled with quartz, epoxy concrete repair materials or coatings filled with sand particles, and epoxy molds filled with metal. 4. This product has lower reaction activity compared to 3-glycidyl ether oxypropyl trimethoxysilane (JH-O187), where the methoxy group in its molecule is replaced by ethoxy group.
