Abstract
The disclosure relates to epoxy-based compositions comprising a decarboxylated rosin acid (DCR) component, suitable as an efficient plasticizer. It further improves hardness, elasticity, UV exposure viability properties of the paint and coating compositions. The DCR increases the bio-based renewable material content of a coating formulation and provide solutions for phthalate-free products. The DCR has a density of 0.9 to 1.0 g/cm, a flash point of 135 to 175° C., an acid value of <50 mg KOH/g, measured according to ASTM D465, and a viscosity of 15 to 60 cSt at 40° C., measured according to ASTM D-445.
