The feasibility of using red mud in coatings based on glyptal resins

Abstract

The possibility of industrial waste – alkaline red mud to be used as the filler of glyptal resins and coatings thereof is considered. It was determined that the most effective way of compounding of said components was in situ combinations during the synthesis of the polymer, providing systems with filling factor up to 36 wt.% with decreased moisture absorption ability in comparison to the initial resin. It was demonstrated that the most probable cause of this performance increase is the formation of chemical bonds between the hydroxyl groups of glyptal and weak van der Waals bonds between the carbonyl group of the resin and surface groups on red mud.
