An Application of Self-Healing Clear Coat

Abstract

The self-healing concept for an acrylic polymer was investigated. In the study, the self-healing performance of the developed varnish was examined. Varnish used; It is a two-component, solvent-based, hydroxylated acrylic resin-based varnish. An isocyanate-based hardener was used as the second component.To demonstrate self-healing performance; Varnish mixed with hardener and thinner in appropriate mixing ratio was applied to the surface with a spray gun. Deformation was created on the varnish, which was cured at 80°C for 30 minutes, and the self-healing performance of this deformation was monitored by gloss measurements.At the end of the study, it was determined that the varnish developed could self-heal at a rate of 90%.
