摘要： PROBLEM TO BE SOLVED: To provide a new polyisocyanante blocked with a secondary amine and derived from a straight-chain aliphatic amine, capable of giving such an organic solution thereof as to have stability for a long period and not to show a tendency toward solidification as a result of, for example, crystallization, even after an elapse of several months. SOLUTION: This blocked polyisocyanante with storage stability is produced by reacting a polyisocyanante with a biuretizing agent, so as to make biuret groups of formula (I) exist in a final blocked product in an amount of 5-45 eq% based on a total amount of all of free and blocked NCO groups; and then blocking at least 95 mol% of remaining free NCO groups with a blocking agent of the formula: R 1 R 2 NH (R 1 and R 2 are each a 1-12C aliphatic or alicyclic alkyl).

摘要： It has been found that a special combination of epsilon-caprolactam blocking agent, diisopropylamine, and 1,2,4-triazole for preparation of stoving lacquers leads to special effects, i.e. deep drawability at room temperature and ripping strength (sic) of the coating obtained. A blocked polyisocyanate mixture contains: (A1) 40-70 equivalents % of a predominantly linear NCO prepolymer of NCO content 5.0-10.0 wt.%, (A2) 30-60 equivalents % of an aliphatic polyisocyante paint, (B1), 30-60 equivalents % of an epsilon-caprolactam, and (B2) 40-70 equivalents % of a diisopropylamine or 1,2,4-triazole as blocking agent, where the amount of the (A1) and (A2) components adds up to 100-110 equivalents %. An Independent claim is included for preparation of the blocked isocyanate mixture by first preparation of (A1), where the diisocyanate is at room temperature and the OH component, i.e. polyester, polyether, di- and triol are added with stirring, and on heating to 100-110 deg C the excess NCO groups react with the OH component, and when the calculated NCO content is attained or slightly exceeded the reaction is stopped, the NCO-prepolymer prepared is diluted with solvent and reacted with the lacquer polyisocyanate (A2), so that (sic) the to tal of the NCO components (A1) and (A2) is used for partial blocking with epsilon-caprolactam (B1) at 100-110 deg C, up to the calculated NCO content, and finally the remaining NCO groups are reacted either with 1,2,4-triazole or with diisopropylamine.
