Patent number: 7989553Abstract: Disclosed is a novel epoxy-amine composition modified a hydroxyalkyl urethane, which is obtained as a result of a reaction between a primary amine (C1) and a monocyclocarbonate (C2), wherein modifier (C) is represented by the following formula (1): wherein R1 is a residue of the primary amine, R2 and R3 are the same or different and are selected from the group consisting of H, alkyl, hydroxyalkyl, and n satisfies the following condition: n?2. Diluents, pigments and additives can be used. Doping with the hydroxyalkyl-urethane modifier imparts to the cured composition superior coating performance characteristics, such as pot-life/drying, strength-stress, bonding, appearance, resistance to abrasion and solvents, etc., in a well-balanced state.Type: GrantFiled: March 26, 2009Date of Patent: August 2, 2011Assignees: Nanotech Industries, Inc., Polymate, Ltd.Inventors: Olga Birukov, Oleg Figovsky, Alexander Leykin, Leonid Shapovalov
