摘要： A mixture of two stabilizers, one including benzene rings bearing hydroxyl substituents and the other containing divalent sulfur atoms, is effective in stabilizing tacky polymers that remain solid up to a temperature of at least 160° C. particularly polymers of isobutylene, so that the polymers give long service in the ambient atmosphere as protective layers coated on aluminum substrates and used to line the interiors of paint baking ovens. When accumulated foreign materials accumulate on the coatings, the coating and the accumulated foreign materials can be decomposed to largely volatile products by heating to a temperature substantially higher than the service temperature but not high enough to melt the metal substrate for the coating.

摘要： Residue that accumulates on metallic molding surfaces during repeated molding of plastics such as PVC can be removed by cleaning with an aqueous solution of a glycol or oligo-glycol monoether, an amine, and a chelating agent. The cleaner is sufficiently effective to replace mechanical blasting that was previously required.
