Abstract: MASKED OXYCARBONYLIXOCANATES ARE PREPARED BY REACTING ARYL OXYCARBONYLISOCYANATES WITH A COMPOUND CONTAINING AT LEAST TWO HYDROXYL GROUPS. WHEN NCO AND OH ARE PRESENT IN EQUIVALENT AMOUNTS, THE COMPOUNDS ARE SUITABLE AS REACTANTS WITH POLYMERS CONTAINING HYDROXYL GROUPS OF THE PRODUCTION OF, FOR EXAMPLE, LACQUERS. WHEN THE REACTION IS CARRIED OUT SUCH THAT OH GROUPS ARE PRESENT IN EXCESS OF THAT REQUIRED TO REACT WITH THE AVAILABLE -NCO, THE COMPOUNDS, WHICH ARE SELF CROSS-LINKING, ARE SUITABLE FOR THE PRODUCTION OF, FOR EXAMPLE, CROSS-LINKED SYNTHETIC RESINS.

Abstract: 1331098 Polyurethane coating powder BAYER AG 27 Oct 1970 [4 Nov 1969 (2)] 50897/70 Heading C3R A coating powder, suitable for electrostatic deposition comprises the reaction product of (I) a polyisocyanate having aliphatically bound isocyanate groups, (II) a polyol, M.W. up to 250, having aliphatically bound OH groups, together with 0À5-15% by wt. based on the polyurethane composition of a polyfunctional component which is a material with >2 OH groups (III) and/or a polyisocyanate, (IV) with more than two NCO groups and M.W. up to 700. I may be hexamethylene diisocyanate, II may be 1,6-hexanediol and/or neopentyl glycol, III may be trimethylol propane and IV may be a biuret triisocyanate: The reaction mixture may additionally comprise a polyhydroxyl compound with aliphatically bound OH groups having M.W. 250-3000, e.g. a polyester of phthalic acid and ethylene glycol. Conventional pigments and fillers may be present.
