Abstract
The instant invention relates to a rubber lubricant composition characterized by complete wetting of the elastomer surface both before and after vulcanization which gives a matte finish on cooling down that remains soft and does not flake off and which washes off easily after molding whereby there is little of no ooze after several months storage. This comprises (1) polyoxypropylene-polyoxyethylene block copolymer having a molecular weight of the hydrophobe of about 1000 to 12,000 and containing 40 to 80 percent oxyethylene groups and (2) an alkyl phenol ethoxylate.
