SPRAY COATING COMPOSITION Russian patent published in 2011 - IPC C09D5/29 

FIELD: chemistry.

SUBSTANCE: method of applying a coating onto a solid surface for creating a coating which imitates stone involves preparation of fluid composition, addition of a free-radical initiator and depositing the obtained composition onto a solid surface at ambient temperature. The fluid composition contains (a) a matrix from a cross-linkable liquid resin, where the resin is styrene-containing isophthalate-neopentyl glycolic resin or unsaturated methacrylate or arcylate resin, in which (b) granules of cross-linked resin macroparticles, which contain a trihydrate of aluminium oxide, are distributed and (c) a cross-linking accelerator. The cross-linking accelerator contains (in terms of total weight of the composition), (i) 0.1-2.5% sodium carboxylate, where the carboxylate is an octoate, benzoate, naphthenate or a carboxylate based on a fatty acid, (ii) 0.1-2.5% heteroatomic organic compound which is a nitrogen-substituted acetoacetamide or aniline, where the nitrogen substitutes are methyl or ethyl, or substituted 3-mercaptopropionate glycol, pentaerythritol or trimethylolpropane, and (iii) 0.1-2.5% heavy metal carboxylate, where the carboxylate is octoate or naphthenate and where the metal is cobalt, copper or zinc.

EFFECT: fast setting coating which has the outer appearance of uniform granite and uniform thickness.
