Abstract: The present invention relates to the use of thermosetting polyurethane urea reactive adhesive compositions which are stable at ambient temperature but rapidly set at higher temperatures, wherein the adhesive comprises stabilized finely-divided polyisocyanates of retarded reactivity of which 0.1 to 25% of the NCO-groups are surface-modified and higher and/or lower molecular polyamines (optionally with polyols as additional reactive components). An important feature of these thermosetting reactive adhesive compositions is their capacity for storage at ambient temperature and their spontaneous increase in viscosity at relatively low heating temperatures which prevents the adhesive from running off during the heating period when applied to vertical surfaces.

Abstract: The present invention is directed to a process for the production of suspensions of finely-divided polyisocyanates which are obtainable by the surface reaction with from 0.1 to 25 equivalent percent of reactive group per NCO of stabilizers in relatively high molecular weight polyols and/or relatively high molecular weight polyamines having molecular weights from 400 to 6,000 optionally with addition of lower molecular weight polyols and/or aromatic amines having molecular weights of from 60 to 399, which are characterized in that unreacted quantities of stabilizers in the suspension are subsequently partially or completely deactivated by addition of substances having an acylating and/or neutralizing and/or alkylating effect and/or adsorbing effect as "deactivators". In particular, mono- and/or polyisocyanates are used as "deactivators". Deactivated suspensions obtainable in this way do not exhibit rising thickening temperatures during the production of polyurethanes, in particular in large-volume shaped articles. The present invention also relates to deactivated suspensions obtainable by the present process and to the use thereof for polyurethane production.

Abstract: The invention relates to novel compositions for coating purposes comprising (A) polyvinyl plastisols, (B) surface modified, finely divided, stabilized polyisocyanates with retarded reactivity, in which 0.1 to 25 equivalents-% of the isocyanate groups of the unstabilized polyisocyanate have been deactivated on the surface, preferably by a reaction with polyamines, hydrazine, alkylhydrazines, polyhydrazide compounds and/or selected amidine and/or guanidine compounds; and (C) plasticizers and/or lightly branched, relatively high molecular weight polyhydroxyl compounds having melting points below 60 DEG C. and compatible with PVC plastisol. The invention also relates to the use of these storage stable but heat curable mixtures as primers for PVC coatings on plastics, foils, textile sheet products or filaments and as primer coats for flocking.

Abstract: This invention relates to solid reaction products of aliphatic, cycloaliphatic or araliphatic mono- and/or polyisocyanates and organic, weakly acid mono- and/or polycarboxylic acids for the production of cellular plastics articles and particularly polyurethane foams. The products of the present invention may also be in the form of mixtures with carboxylic acids. The products are suitable for the production of cellular or porous plastics articles, but are preferably used in the preparation of cellular thermoplastic polyurethanes and semi-rigid and particularly rigid polyurethane integral skin foams having a compact outer skin formed by foaming the reaction mixture in closed molds.
