Adhesion Properties Of Benzoly Peroxide Crosslinked Epoxidized Natural Rubber (ENR 25) - Based Pressure Sensitive Adhesives

The objective of this study was to evaluate the influence of crosslinking density, rate of testing and thickness coating on the adhesion properties of epoxidized natural rubber (ENR 25)-based adhesives using coumarone-indene, gum rosin and petroresin as the tacki fiers. Toluene and polyethylene t...
