WEAR-RESISTANT POLYMERIC COMPOSITION Russian patent published in 1995 - IPC

FIELD: anticorrosive materials. SUBSTANCE: composition, p.: nonsaturated polyethermaleinate resin 100; product of interaction of allyl alcohol with toluylenediisocyanate 35-23.5; polyisocyanate 7.65-76.50; polymerization initiating agent 0.1-8.0; block-copolymer of polyorganosiloxane and polyhydroxyalkylene 0.1-3.0; fluorinated alcohol 0.5-10.0; activated basalt scale 5-350. Composition is prepared by mixing of resin, addition of polyisocyanate, block-copolymer, fluorinated alcohol and activated basalt scale to the mixture. After stirring polymerization initiating agent is added. Composition is applied by spatula or brush. Complete hardening is occurred for 10 days. Coating properties: water absorption after 20 days H₂O per 1 g is 8,7-9,2·10³, wear-resistance is 7,8-10,5 mg/s·10^-3. EFFECT: enhanced quality of composition. 1 tbl
