Silane Coupling Agent KH-331:n-Octyltrimethoxysilane

Silane Coupling Agent KH-331:n-Octyltrimethoxysilane is a kind of short carbon chain alkyl functional alkoxy silane. KH-331 (n-propyl-trimethoxysilane) can be infiltrated from the surface to its internal, Si-OH formed after the hydrolysis of trimethoxy can react with the hydroxyl of materials, and cross linked with each other. And n-propyl are given material with good hydrophobicity, effectively prevents water and moisture penetration into the material inside, which play a role of protecting material and hydrophobic agent. KH-331 is a colorless, low viscosity transparent liquid with solvent odor similar to alcohol. KH-331 can be soluble in non-polar solvents such as alcohol of aliphatic solvents and aromatic solvents, solvent oil.. KH-331 mainly for the following purposes:
1. Sol - gel (Sol-Gel) synthesis of raw materials: This product is an important monomer of synthesis of siloxane sol - gel can be hydrolyzed to be temperature-controlled reaction precursor. This pre-hydrolyzate can get from the react of silanes have organic reactions function (such as the KH-560) ,silicate and even inorganic silica sol .This hydrolyzate can be modified by organic resin or inorganic-Nazi material You can also build a kind of inorganic - organic network structure by adding silanes have organic reactions function (such as amino-silane)or organic resins. The mixture can be cross linked and cured by conventional methods. Through this new technology we can get coatings with better resistance to abrasion, ultraviolet light and better fire retardant.
2. Inorganic filler surface treatment agent: This product can significantly improve the filler in plastics, rubber and resin in the dispersion and compatibility for most inorganic powder materials and plastics, rubber and resin.
3. Pigment dispersant: The deal has a better dispersion of pigments, resin compatibility and hiding, so that the color is more gorgeous.
