METHOD OF PREPARING COATING ADDITIVE CONTAINING METAL-CONTAINING NANOPARTICLES, AND OBTAINED PRODUCT Russian patent published in 2012 - IPC C08J3/215 C09D1/12 C09D5/10 B82Y30/00 

FIELD: chemistry.

SUBSTANCE: invention relates to a method of producing an additive used in paint and lacquer for endowing them with defined properties, particularly biocidal and electrical properties which protect from the effect of UV radiation and prevent inflammation. The method is based on using metal nanoparticles, which can be in a water-organic medium or alternatively in form of dry powder, e.g., Ag, Au, Cu and Bi, subjected to treatment which enables to include them into coatings used in a wide range of ambient conditions. The method involves use of solvents, surfactants, dispersants and resins which makes the additive compatible with the end coating.

EFFECT: method ensures excellent distribution and dispersion of nanoparticles in the entire coating without the need to use an inorganic substrate.
