Adhesion Properties of Zinc-oxide Filled Epoxidized Natural Rubber/ acrylonitrile-butadiene Rubber Blend Adhesives
The effect of zinc oxide loading on the adhesion properties of epoxidized natural rubber (ENR 25) / acrylonitrile-butadiene rubber (NBR) blend adhesives was studied using coumarone-indene resin and toluene as tackifier and solvent respectively. Five different loadings, i.e. 10, 20, 30, 40 and 50 phr...
