Abstract
A water washable protective coating composition for application to surfaces subjected to contact with airborne paints which composition comprises an ionomer of a copolymer of an acrylic acid and an alpha-olefin. The composition forms a protective, clear low-slip coating layer upon surfaces, and is readily removable with heated water.
Claims14
A protective coating composition consisting essentially of:
- (a) about 50 to 95% water;
- and
- (b) about 50 to 5% of a random ionic copolymer consisting of monomeric repeating units derived from the following:
- i) an .alpha.-olefin of the formula RCH.dbd.CH.sub.2, wherein R is selected from the group consisting of hydrogen and alkyl radicals having from 1-8 carbon atoms;
- and
- ii) an .alpha.,.beta.ethylenically unsaturated carboxylic acid selected from the group consisting of acrylic acid, methacrylic acid, itaconic acid and ethacrylic acid, wherein at least 50% of the carboxylic acid groups in said .alpha.,.beta.ethylenically unsaturated carboxylic acid are neutralized with metal ions;
- and,
- wherein following application of paint over said composition, said composition may be removed from a surface by washing with water.
