UV RESISTANT POLYMER COMPOSITION FOR TREATMENT OF FIBRE GLASS FILAMENTS Russian patent published in 2017 - IPC C09D163/00 C08L63/00 C08K5/00

Abstract RU 2620057 C1

FIELD: chemistry.

SUBSTANCE: composition comprises the following component ratio by pts. wt.: 100 of epoxydiane resin, 70-80 of hardener, 0.5-0.8 of accelerator, 0.5-2 of synergistic mixture, 1-2 of phthalocyanine pigment. Isomethyltetrahydrophthalic anhydride (IMTHPA) is used as a hardener. The synergistic mixture comprises equal parts of stabilizers, absorbers, anti-oxidants.

EFFECT: invention improves resistance of the polymer composition to UV and climatic effects under conditions of significant annual temperatures fluctuations.
