BLEND COMPOSITION OF POLYMER COMPOSITION FOR RESTORATION OF DESTRUCTIVE SECTIONS OF WOODEN STRUCTURES ELEMENTS Russian patent published in 2019 - IPC C08L63/02 C08K5/17 C08K5/10

Abstract RU 2697564 C1

FIELD: chemistry.

SUBSTANCE: invention relates to production of epoxy compositions of cold hardening, which can be used in construction. Polymer composition for repair and restoration of building wooden structures contains an uncured epoxy-diane resin, a hardener - polyethylene polyamine, a plasticiser - dibutyl phthalate and acetone as a diluent.

EFFECT: invention enables to obtain a polymer composition with low initial viscosity, high penetrating power in the wood capillary structure, required viability, high strength and adhesion to wood.
