ABSTRACT:
An aqueous cleaning, coating and polishing composition consisting essentially of 1 to 20% by weight of a water insoluble alkali soluble addition polymer comprising at least one hydrophilic monomer selected from acrylic acid and methacrylic acid and at least one hydrophobic monomer selected from alkyl acrylate and alkyl methacrylate, where alkyl has from 1 to 6 carbon atoms, and at least one hydrophobic monomer selected from styrene and monoalkylstyrene where monoalkyl has from 1 to 6 carbon atoms, 1 to 13% by weight of an alkyli soluble 2:1 to 3:1 styrene:acrylic acid resin, 5 to 15% by weight of a fugitive plasticizer, 1 to 3% by weight of a permanent plasticizer, 0.01 to 0.05% by weight of an anionic or nonionic fluorocarbon surfactant leveling agent, 0.0003 to 0.003% by weight of a dimethylpolysiloxane antifoaming agent; 0.0003 to 0.003% by weight of a 1,2-benzoisothiazol-3(2H)-one or 3(2H)-isothiazolone preservative, ammonia to provide a pH of 8.0 to 9.6 and water q.s. to 100%, the composition having a content of solids of from 10 to 25% by weight.
