RADIOPARENT POLYMER COMPOSITION Russian patent published in 2015 - IPC C08L63/00 C09D163/00 C09D163/02 C08J5/24 H01Q17/00 H01Q1/42 

FIELD: chemistry.

SUBSTANCE: radioparent polymer composition includes an epoxy oligomer, a polyether modifier, pigments and an organic solvent. The composition additionally contains filler - glass microspheres and a curing agent - mixture of polyethylene polyamine and a 50% solution of hexamethylenediamine or 2-methylpentamethylenediamine in isopropyl alcohol, with the following ratio of components, wt %: epoxy oligomer 19-29; modifier 20.7-31; pigments 11.5-18.3; filler 3-10; curing agent 1-5; organic solvent 21-35. As pigments, the composition contains a mixture of titanium dioxide with chromium oxide, or with zinc white, or with chromium oxide. As the polyether, the polymer composition contains a polyether which is a product of polycondensation of ethylene glycol and glycerine with sebacic acid. The organic solvent used can be ethyl glycol acetate, butyl acetate, xylene, methyl ethyl ketone or mixture thereof in ratio of 4:4:1:1.

EFFECT: low water absorption and high fungal resistance while maintaining adhesive properties of the polymer composition.
