EPOXY COMPOSITION FOR GLASS-REINFORCED PLASTICS Russian patent published in 2001 - IPC

Abstract RU 2172328 C2

FIELD: chemistry of polymers, more particularly manufacture of glass-reinforced plastic. SUBSTANCE: composition comprises, wt parts: epoxydiane resin, 5.4-5.6: epoxy-triphenol resin, 50.4-50.6: dicyanodiamine, 1.5-1.7: 9-bis-N, N'-dimethylcarbamido diphenylmethane hardener 2.74-2.7: ethyl alcohol, 11.5-18.5; acetone 19.5-30.5; and chlorocopper complex such as dichloro(bis)-2- mercapto-5- trichloroacetylamino-1,3,4-triadiazole copper (II), 0.05-0.5. Composition has improved physico-chemical properties, more particularly homogeneity and nonporosity after being hot hardened using maximum high heating rate for alcohol-acetone solutions and imparts high strength properties to composition-based glass reinforced plastics. EFFECT: improved properties of the copy composition. 3 tbl
