Synthesis and properties of UV-curable polyurethane surface coating using (Rosinified phenolic resin-coconut alkyd resin) blends

Author(s): Bhaumik M Patel, Nirmit N Patel
Abstract: UV-curable coatings are a boon to the paint industry, as they not only reduce VOCs but also speed up production processes and provide protective, durable and attractive finishes. UV-curable polyurethane acrylates have been synthesized from polyester polyol (hydroxy terminated alkyd resin and rosinified phenolic resin), toluene diisocyanate and reactive diluents i.e., Hydroxyethylmethylacrylate (HEMA). In this paper several formulations of UV-curable polyurethane acrylate resins were used to study the effect of reactive diluents on performance properties. It was observed from the results that UV-cured polyurethane acrylate resin films on metal surfaces exhibit excellent gloss (60°), mechanical, and chemical properties.
