ABSTRACT:
A coating composition for providing (especially temporary protective) coatings on surfaces (especially the hydrophobic paintwork of newly finished motor vehicles) which comprises particulate copolymer dispersed in water containing less than 10 wt % of volatile organic solvent. The particulate copolymer comprises 7 to 14 wt % acrylic or methacrylic acid, 0.1 to 10 wt % hydrophilic monomer (e.g. methacrylamide) and other monomers. The coatings are transparent, abrasion resistant, tenacious yet easily removable to produce environmentally acceptable effluent.
