FIELD: chemistry; manufacturing technology.
SUBSTANCE: invention relates to epoxy vinyl ester composition and can be used for making articles from polymer composite materials by vacuum infusion, including using filler made by weaving, in automotive industry, chemical machine building, power, construction, machine building, ship-building, aviation industries and other industries. Composition contains an epoxy vinyl ester base containing epoxy vinyl ester resin, initiator, phenol-type inhibitor and peroxide-type curing agent – organic peroxide based on methyl ethyl ketone. Epoxy vinyl ester base as initiator contains cobalt octoate and additionally contains modifiers – polyisocyanate, surfactant and elasticiser.
EFFECT: providing preservation of viscosity and gel-forming time of composition during prolonged storage at temperature 25 °C and high strength at static flexure.
