ABSTRACT:
By causing a rubber product to be immersed into or coated with a treating liquid prepared by adding hydrogen peroxide and other additives such as surfactant, alcohol, thickening agent, other surface tension depressant into an aqueous acetic acid or formic acid solution, it becomes possible to efficiently epoxidize the surface layer of the rubber product to thereby provide the rubber product surface with non-adhesive property, sliding property and other barriering properties, without causing toxic gases and contamination due to powder dust during the manufacturing process and without deteriorating properties inherent in the rubber product such as elasticity, elongation and tensile strength.
