Adhesive
Abstract
Abstract The invention provides adhesive consisting of a solution of an unsaturated polyester which is a product of interacting dicarboxylic acids with polyols in an unsaturated monomer, an urethane modifier, and a polymerization agent with the following ratio between the components in weight parts: ______________________________________ unsaturated polyester solution in unsaturated monomer 100 urethane modifier 10-300 polymerization agent 0.1-15. ______________________________________ The urethane modifier is the product of the interaction of a urethane prepolymer which is a product of interaction of aromatic diisocyanate with hydroxyl-containing polyesters with a fluorinated alcohol of the general formula C n F 2n+1 OH, where n = 1-15, and with ethyleneglycol monomethacrylate. The proposed adhesive is suitable for repairing oil reservoirs and oil tanks, for sealing and mounting oil pipelines, for strengthening corroded ship structures, for bonding together natural stone and glass-fibre plastics in air, in water, and in a petrochemical medium.
