PURPOSE:To produce rust preventing wax having improved splash resistance by adding specified percentages of an ethylene-propylene copolymer having a specified mol.wt., polyisoprene and an inorg. filler to rust preventing wax contg. at least one of metallic salts of sulfonic acid, etc., as a basic component. CONSTITUTION:Rust preventing wax contg. at least one of metallic salts of sulfonic acid, oxide wax and lanolin as a basic component is prepd. and at least one of an ethylene-propylene copolymer and noncrystalline polypropylene each having <=10,000mol.wt., polyisoprene and an inorg. filler are added to the wax by 1-20wt.%, 1-40wt.% and 1-40wt.%, respectively. The polyisoprene may have hydroxyl groups or other functional groups in the molecular chain and it may have not the functional groups. Calcium carbonate, mica or talc may be used as the inorg. filler. Rust preventing wax having improved splash resistance and useful to prevent the rusting of the outer surface of an automobile body is obtd. |
