FIELD: chemistry.
SUBSTANCE: two-component lubricate composition comprising (A) a precursor comprising (a) an aminoalkoxysilane and (b) a polymer or copolymer containing carboxylic acid and/or anhydride, both of which have functionality F≥3, and (B) a binder comprising a multifunctional epoxy resin with functionality F≥3. Fiberglass coated with the claimed composition and a reinforced composite material made therewith, as well as the method for applying a two-component lubricate to fiberglass and applying a lubricate composition to improve the mechanical properties of the composite material reinforced with fiberglass are proposed.
EFFECT: fibreglass lubricated by the interaction product of the proposed composition, imparts a higher resistance to hydrolysis to composite materials with a polymer matrix reinforced with the said fiber, the composition of the invention is particularly effective for use with polyester resins.
