DRYING SUBSTANCE FOR SELF-COATING COAT COMPOUNDS Russian patent published in 2017 - IPC C09D167/06 C09D7/04 C09D7/12 C08K3/10 C08K13/02 C08K5/3467 C09F9/00 C09F7/02 C08K5/00 

FIELD: chemistry.

SUBSTANCE: self-oxidizing polymer composition includes a drying agent obtained by mixing 1,4,7-trialkyl-1,4,7-triazacyclononane (L) and a manganese salt having the general formula Mn²⁺[X]_n, in which, as the anion X, PF₆^-, SbF₆^-, AsF₆^-, BF₄^-, B(C₆F₅)₄^-, Cl^-, Br^-, I^-, NO₃^- or R₂COO^-, and in this case n=2, or the anion X is SO₄^2-, and in this case n=1, where R₂ is C₁-C₂₀-alkyl. The 1,4,7-trialkyl-1,4,7-triazacyclononane (L) is present in the mixture in such an amount that the molar ratio of L:Mn is at least 1.25:1 and preferably at least 1.5:1. A coating composition consisting of a self-oxidizing polymer composition, a method for coating a substrate, a substrate, and applying the composition to paints, compositions, varnishes, inks and glazes and using a mixture of L and Mn as a drying agent for an air-drying self-oxidizing polymer composition are also disclosed.

EFFECT: provision of cobalt-free catalysts that can provide rapid drying and at the same time contribute to reducing the yellowness of the coating compositions.
