Abstract

1348028 Contact adhesive coating BAYER AG 19 April 1971 [7 Feb 1970] 21269/71 Heading B2E [Also in Division C3] A suport material is continuously coated with a reaction mixture which reacts to form a layer of contact adhesive and comprises (a) a polyalkylene ether polyol of M.W. 3,500 to 10,000 prepared by propoxylation of a starter compound having a M.W. of at most 250 and at least 2 active hydrogen atoms, followed by ethoxylation of the resulting polypropylene ether polyol. The quantity of ethylene oxide used being such that 5 to 45 mols %, based on the polyalkylene ether polyol, of terminal polyethylene ether units are obtained, (b) tolylene diisocyanate and (c) a tertiary amine, the tertiary amine comprising from 0.2 to 5% by weight of the reaction mixture and the NCO OH ratio being 0.6:1 to 1.4:1. The starter molecule for the polyalkylene ether polyol may be water, ethylene glycol, propane-1,2-diol, propane-1,3-diol trimethylolpropane, glycerol, pentaerythritol ethylene diamine, tetramethylenediamine or hexamethylenediamine. The tolylene diisocyanate is suitably 2,4-toluene diisocyanate or its commercial mixtures with the 2,6-isomer. Suitable tertiary amines are N,N-diethylbenzylamine, N,N-dimethylpiperazine and especially 1,4-diaza-bicyclo-(2,2,2)- octane. Immediately after mixing the liquid mixture is applied to support materials such as paper, textiles and plastics foils, especially foils made of polyterephthalic acid polyesters or plasticized polyvinyl chloride and linen.
