FIELD: chemistry.

SUBSTANCE: invention pertains to a binding substance for reinforced plastics, which can be used as construction coating or protecting concrete, reinforced concrete, metallic and other surfaces from aggressive media and abrasive wearing, as well as making general use moulding products, used in chemically aggressive media. The binding substance consists of the following components, in wt %: 4.5-70 epoxy-diane resin, 1-30 chlorinated polyvinylchloride solution in an organic solvent, 8-25 reactive diluent, and amine type hardener constitutes the remaining wt %. The reactive diluent used is epoxy rubber adduct, obtained through co-condensation of functional groups of epoxide resin and liquid nitrile rubber, and if necessary glycidyl ether of phosphorous acids with general formula: R=-CH₃, -OCH₃, . The binding substance also contains 0.5-30 wt % o-xylol solvent and/or up to 10 wt % pigment.

EFFECT: invention allows for increasing water absorption and resistance to effects of oil-products, acids, bases, gaseous acids, thereby providing for resistance to abrasive wearing.
