Abstract
Through this work, water-thinnable thermosetting acrylic resins have been developed to overcome the major drawback of conventional coatings, viz. VOC emission. For achieving this, a series of TSA resins were prepared by reacting 2-hydroxyethyi methacrylate (HEMA) and acrylic acid (AA) as monomers in butanol as solvent in presence of benzoyl peroxide (BPO) as initiator. The TSA resins, prepared under optimised conditions, were made waterthinnable by neutralising with ammonia. The applied films of coatings were baked at 90°C for 30min to effect film cure. Cured films were evaluated for their optical, thermal, mechanical and chemical resistance properties to ascertain the commercial utility of these eco-friendly thermosetting acrylic resins for use in automotive topcoat formulations.
