| titleOfInvention | Blocked aliphatic diisocyanates or diisocyanate adducts |
| abstract | Blocked Aliphatic Diisocyanates or Diisocyanate Adducts Disclosed is a blocked aliphatic diisocyanate or diisocyanate adduct, which is obtainable by reacting: A) at least one member selected from the group consisting of: (1) an aliphatic diisocyanate of the general formula: OCN-R-NCO (I) (in which R is a C4-C12-alkylene radical which may contain one to three methyl or ethyl groups or, instead of 4 CH2 groups, a cyclohexane radical), and (2) an adduct of the aliphatic diisocyanate of the formula (I) which contains an isocyanurate group, biuret group or urethane group and which has free isocyanate groups, with B) a sterically hindered secondary amine having a boiling point of at least 160°C and being represented by the general formula: (see fig. II) (in which R1 and R2 are identical or different and are each independently hydrogen, alkyl, cycloalkyl or aralkyl or two of R1 or two of R2 together with the carbon atom to which they are attached or R1 and R2 together with the HN group and the two carbon atoms to which they are attached form a ring which may be substituted by one to four alkyl groups or, instead of a CH2 group, may contain an oxygen atom or a -NH group), wherein the sterically hindered secondary amine is employed in an amount of 0.5 - 1 mol per mole of isocyanate groups in the aliphatic diisocyanate or the adduct. The blocked diisocyanate or adduct thereof is useful as a hardener in a polyurethane powder coating composition. |
