<p>PROBLEM TO BE SOLVED: To ensure easy and fail-proof mounting and to prevent the leakage of semen by incorporating oil of a paraffinic system into a copolymer of polyethylene(PE) and styrene. SOLUTION: An oil of about 98% paraffinic system and about 2% naphthene system is incorporated into the copolymer of PE and styrene. A citrus system may otherwise be used for the oil. Further, carbon and hydrogen are slightly added to the copolymer in both systems. This coating liquid for the penis is applied to the surface from the front end to the root of the penis and is cured before a sexual action. The sexual action is carried out after the curing and after the action, the coating is rolled up and peeled, by which the coating is removed. Since the straight chain of the main agent with this constitution is long, the elongation characteristic is good and the coating liquid is harmless to man and beast. Impact absorptivity and wear resistance are improved and quick drying is made possible.</p> |
