3-Chloropropyltriethoxysilane
Stable under normal temperature and pressure, colorless and transparent liquid, easy to hydrolyze, release ethanol, and generate corresponding condensate. The chlorine atom in the intramolecular C-Cl bond can be replaced by hydroxyl, amino and carboxyl groups through classical organic chemical reactions.
It can be used to produce active silicone oil and silane coupling agent, and also can be used as coupling agent of epoxy resin composite.

3-Chloropropyltrimethoxysilane
It is mainly used as a coupling agent, such as for the treatment of glass fiber to improve the adhesion with epoxy resin. It is suitable for the coupling of glass fiber surface treatment, epoxy resin, polyurethane, polyamide and other adhesives or composite materials.
Stable under normal temperature and pressure, avoid oxidant, acid and alkali, and water contact.
Colorless or light yellow transparent liquid, soluble in benzene, ethanol, gasoline, insoluble in water.

3-Mercaptopropylmethyldimethoxysilane
It is a silane coupling agent, mainly used for the treatment of rubber filler and the synthesis of linear mercapto silicone oil.
It is suitable for the elastomer of sulfur curing and metal oxide curing systems. It can combine inorganic fillers (such as silica, clay, mica, etc.) with rubber chemical bond. Thus, the mechanical properties of the elastomer reinforced by inorganic fillers can be improved.
It can be used as adhesion promoter, surface modifier, cross-linking agent and dispersant. It is mainly used to improve the binding force and compatibility of inorganic mineral powder material and fiber to polymer (resin) and the adhesion and water resistance of resin layer to inorganic substrate.
Applicable resins include acrylic resin, polyurethane, natural rubber, butyl rubber, nitrile rubber, chloroprene rubber and polysulfide rubber.
