Silane KH-172：Vinyltri(2-methoxyethoxy)silane

Silane KH-172：Vinyltri(2-methoxyethoxy)silane, its molecular structure contains unsaurated double bonds.Vinyl of the KH-172 can react with many kinds of resins. While, the Si-OH formed after the hydrolysis of the 2 - methoxyethoxy can have condensation reaction with the hydroxyl on the surface of the inorganic materials. Thus erected between inorganic materials and resins,”molecular bridge”, to play a role in coupling.
KH-172 is a colorless and transparent, low viscosity liquid, Its smell is somewhat similar to that of benzene solventIt can be dissolved in aliphatic solvents and aromatic solvents such as alcohol, ether, ketone It is also soluble in water, and however, hydrolysis occurs. Hydrolysates are not stable, and the storage period is short.
KH-172 is primarily used as adhesion promoter, surface modifiers, and cross-linking agent and dispersant. Vinyltri(2-methoxyethoxy)silane is to upgrade the combination of power and compatibility between inorganic mineral powder material, fiber and polymers (resin). And to improve the adhesion, water resistance between resin coating and the inorganic substrate.
KH-172 Typical uses include aluminum hydroxide, magnesium hydroxide flame retardant low smoke zero halogen flame retardant electrical material highly filled materials (HFFR), silane cross-linked polymer synthesis and as a comonomer preparation of silicone-modified polymer (such as acrylic emulsions, styrene-butadiene latex, etc.), etc.
