(I) with improved flow properties is also claimed, with particle size 2-25 microns and contg. 0.01-10 wt.% (II) as above. Amt. of (II) is pref. 0.1-2.5 wt.%; (II) is added at any point in the prodn. of (I), pref. after pptn. of solid (I) and before working-up and milling, or after drying and milling (I); (II) is used with other additives.

Abstract: Heat-curable reactive systems comprising mutually homogeneously immiscible polyethers and polyesters, optionally OH- and/or NH2-terminated, low-molecular-weight chain extenders, optionally conventional assistants and a solid polyisocyanate having a melting point above 80 DEG C, in which the polyester component is in the form of a mixture of solids (powder or granules).

Abstract: The present invention relates to cold setting compositions of (A) suspensions of solid polyisocyanates with retarded reactivity in aliphatic polyamines, and which are stable under storage due to a polyadduct covering, and (B) polyols and/or water. The activation of the composition is caused by the polyol or water. Additional activating materials can also be added for hardening. Such compositions, which already harden at ambient temperature, are stable under storage, have a long potlife for processing and, in relation to the potlife, have a very short hardening time to the final reaction product.

Abstract: Encapsulated polyisocyanates are prepd. by i) mixing a solid, finely divided polyisocyanate (I) of m. pt. above 38 deg. C with a polyisocyanate (II) of different compsn. in ratio 0.05-50 pts. wt. (II) per 100 pts. wt. (I) at temp. below m. pt. of (I), opt. (II) being dissolved or suspended in an inert, low polar organic solvent, and ii) reacting the coated (I) particles with approx. equiv. amt. of a cpd. (III) reactive to isocyanates to form a polymer capsule from (II) and (III) on the solid core particles of (I). - Finely divided polyisocyanates of retarded reactivity, encapsulated in a different polymer, opt. suspended in a higher mol. polyol and/or higher mol. polyamine, and obtainable by above process through reaction of solid (I) particles, coated by (II), with a (III).
