HOUSEHOLD GENERAL-PURPOSE ADHESIVE ON A POLYURETHANE BASIS

摘要

A b s t r a c t The invention relates to the use of a substantially clear and at least largely solventless, aqueous, onecomponent polyurethane dispersion based on the reaction products of - a polyol mixture consisting completely or partly of polypropylene glycol, - a mixture of polyfunctional isocyanates consisting completely or partly of .alpha.,.alpha.,.alpha.',.alpha.'-tetramethyl xylene diisocyanate (TMXDI), - a functional component capable of salt formation in aqueous solution and - optionally a chain-extending agent as a universal household adhesive and to a process for its production in the absence of inert solvents.
