Abstract: Process for cleaning equipment and equipment cleaner for implementing the process.The invention relates to a process for cleaning equipment contaminated with lacquer residues, in which the lacquer residues are removed with a solvent mixture and an equipment cleaner based on a solvent mixture for implementing the process. The solvent mixture containsA) 15-35 wt. % of one or more glycol ethers of the general formula IOH--(CH.sub.2 --CH.sub.2 --O).sub.m --R.sub.1 Iwhere R.sub.1 =C.sub.1-4 -alkyl and m=1 or 2 andB) 65-85 wt. % of one or more aliphatic ketones of the general formula II ##STR1## where R.sub.2=C.sub.1-3 -alkyl and R.sub.3 =C.sub.1-3 -alkyl and R.sub.2 and R.sub.3 may be identical or different.

Abstract: The invention is directed to an aqueous coating composition composed of chlorinated polyolefins and one or more water-borne, self-emulsifying epoxy resins. The epoxy resin is formed from a combination of aromatic polyols, diepoxy compounds and a condensation product formed from diepoxy compounds and aliphatic polyols. The composition is free of emulsifiers yet forms homogenous mixtures in aqueous media. The composition exhibits strong bonding to plastic substrates.

Abstract: A coating and primer composition suitable as a primer for plastics such as a polyolefin which comprises: a) from about 1 to 5% by weight of ethylene/vinyl acetate copolymers, b) from about 0.5 to 5% by weight of chlorinated polyolefins, c) from about 0.01 to 5% by weight of an epoxy resin; and d) from about 85 to 98.49% by weight of an organic solvent, and optionally paint auxiliaries, pigments and/or fillers.A method of priming plastic surfaces of an object, especially polyolefins, and particularly polypropylene, is also provided which comprises applying the aforesaid composition to a plastic surface and drying the same prior to applying paint or finish coating.
