  • Drier for auto-oxidisable coating compositions
    Patent number: 9587085
    Abstract: A drier for air-drying an auto-oxidizable resin composition, said drier comprising: 1,4,7-trialkyl-1,4,7-triazacyclononane (L); a manganese salt having the general formula Mn2+[X]n, wherein anion X is selected from PF6?, SbF6?, AsF6?, BF4?, B(C6F5)4?, Cl?, Br?, I?, NO3, or R2COO? in which case n=2, or the anion X is SO42? in which case n=1, and wherein R2 is C1-C20 alkyl optionally substituted with heteroatoms, C6-C20) aryl optionally substituted with heteroatoms, or a polymeric residue; wherein the 1,4,7-trialkyl-1,4,7-triazacyclononane (L) is present in the mixture in an amount such that the molar ratio of Mn:L is at least 1.25:1 and preferably at least 1.5:1.
    Type: Grant
