COATING COMPOSITE COMPRISING POLYCONDENSATION PRODUCT HARDENING BY OXIDATION, POLYTHIOL AND SICCATIVE Russian patent published in 2005 - IPC

FIELD: coating composites.

SUBSTANCE: invention relates to the coating composite. The composite comprises the following components: alkyd resin hardened by oxidation - polyunsaturated product of condensation with by-side groups in the amount above 20% by the condensation product mass wherein by-side groups comprise unsaturated bond carbon-carbon, polythiol with two or more SH-group and siccative. Equivalent ratio of thiol-functional groups to unsaturated bonds carbon-carbon is less 0.3 but preferably between 0.01 and 0.25. Vanadium and manganese compounds are used as a siccative. The coating composition can comprise chelating agent accelerating the hardening process and a solvent. Invention provides preparing the stable composite rapidly hardened at low temperature and exhibiting the sufficient time for its storage. Invention and the composite can be used as clear lacquer, decorative coating, for example, for doors and window frames, in industry for wood substrates and for substrates made of metal, concrete, plastics and other materials.

EFFECT: valuable properties of composite.
