A pre-mixed composition for use as a coupling agent in a vulcanizable rubber compound containing siliceous filler, said pre-mixed composition comprising about 20-85 weight percent of an organosilane and about 9-70 weight percent of a fatty acid dispersion aid comprising fatty acid and a salt-forming agent, said organosilane and said fatty acid dispersion aid being pre-blended together prior to addition to the vulcanizable rubber compound.
A pre-mixed composition for use as a coupling agent in a vulcanizable rubber compound containing siliceous filler, said pre-mixed composition comprising about 20-85 weight percent of bis(3-triethoxysilylpropyl)-tetrasulfane, about 10-40 weight percent powderizing agent, and about 9-70 weight percent of a fatty acid dispersion aid comprising fatty acid and a salt-forming agent containing a metal selected from the group consisting of calcium, zinc, aluminum, magnesium, cadmium, barium, potassium, and sodium, said bis(3-triethoxysilylpropyl)-tetrasulfane, said powderizing agent, and said fatty acid dispersion aid being pre-blended together prior to addition to the vulcanizable rubber compound.
