STUDY OF EPOXY RESIN MODIFICATION WITH MALEIC ANHYDRIDE AND THE POSSIBILITY OF ITS APPLICATION FOR THE PROTECTIVE COATINGS
Abstract and keywords
Abstract (English):
The paper proposes a method of modifying ED-20 epoxy resin with maleic anhydride to ensure its functionalisation. IR spectroscopy confirmed the modification of ED-20 resin with maleic anhydride. Modified ED-20 resin was used for production of protective coatings of ‘flexible’ stone type. The proposed composition of the polymer base of the coating has the required functional properties and allows ones to substitute imported acrylic dispersion SORBUS.

Keywords:
modification of epoxy resins, maleic anhydride, IR-spectroscopy, 'flexible' stone, protective coatings
