EPOXY RESIN-BASED CURABLE COMPOSITIONS AND COMPOSITE MATERIALS OBTAINED THEREFROM

摘要

FIELD: chemistry.;SUBSTANCE: composition consists of a mixture and includes components (A), (B) and (C). Component (A) includes an epoxy-resin based composition which includes a mixture (A1) of epoxy resin and (A2) divinylarene dioxide. Component (B) includes a curing composition and component (C) includes a reinforcing material. Viscosity of the curable composition is in the range of about 0.15 Pa·s to about 1.5 Pa·s. The curable composition is intended to provide a cured composite product made from the curable composition. The curable composition provides a cured composite product having Tg which is about 5°C higher than that of a curable composition containing a reaction diluent. The disclosed composition can be used to produce transparent cast products, composite materials, coatings and adhesives.;EFFECT: invention provides high chemical resistance, high solvent resistance and improves other properties, such as high strength and high hardness.;15 cl, 3 dwg, 1 tbl, 2 ex
