A STUDY ON THE REACTIVITY AND PHYSICOCHEMICAL PROPERTIES OF COATINGS BASED ON ACRYLATED BLACK SEED OIL COATINGS THROUGH CROSSLINKING AT AMBIENT TEMPERATURE

Abstract

Environmentally friendly organic coatings which are water-based, have low or no solvents and good physical properties based on the use of acrylate
monomers/acrylate oligomers originating from vegetable oils are gaining attention as we move towards sustainable chemistry. Using thermal methods with
acrylate and methacrylate monomers in the presence of initiators produces transparent films. An analysis on the influence of the nature of initiators shows that
the activity of initiators is arranged in the order: D.1173 > PI.907 > I.184 > TPO > PI.PB, and the content of D.1173 initiators at 3% of the reaction occurs quickly
after 3 hours at 40°C, producing a tightly crosslinked transparent film. The reactivity and properties of the coatings formed by acrylated black seed oil at ambient
temperature have been studied using internal calibration, testing relative hardness, gel content, swelling ratio, impact resistance, and gloss. The research results
provide a basis for the development of advanced, environmentally friendly organic coatings using black seed oil - a type of vegetable oil with naturally-
epoxidized groups native to Vietnam.
