VANABIO® MS2231

3-Mercaptopropyltriethoxysilane

VANABIO® MS2231 is a bifunctional organosilane possessing a reactive organic mercapto and a hydrolyzable inorganic methoxysilyl group. VANABIO® MS2231 is a clear, colorless to light yellow liquid with a slightly mercaptan odor. It is soluble in alcohols, ketones and aliphatic or aromatic hydrocarbons.


VANABIO® MS2231 gamma mercaptopropyltriethoxysilane is the equivalent of Momentive's A-1891, Dow's Z-6910 silane.

Application


  • VANABIO® MS2231 can be used as silane coupling agent to improve the adhesion of sulfur cured elastomers (polysulfide, polyurethane sealants) to inorganic fillers (such as silica, clay, glass, mica and talc etc.), fiberglass and surfaces. Mineral-reinforced articles such as shoe soles, rubber rollers and wheels, white sidewalls, and wire and cable insulation also can be produced with lower silane loadings.


  • VANABIO® MS2231 can be used to improve properties of mineral filled elastomer, including modulus, tensile and tear strength, heat buildup, abrasion resistance, resilience, compression set and cure time.


  • VANABIO® MS2231 can be used as a pretreatment on mineral oil silicone or added at the time of compounding.


  • VANABIO® MS2231 can be used to improve low-rolling resistance in silica-reinforced tire tread compounds.


Packing and Storage


  • VANABIO® MS2231 is supplied in 200Kg steel drum or 1000Kg IBC container.


  • In the unopened original container VANABIO® MS2231 has a shelf life of one year in a dry and cool place.
