Performance Chemistry Of Thermoset Surface Coatings

Grant number: LP0212072

Abstract

Surface coatings employed in the COLORBOND® range of pre-painted steel products are remarkable materials that are warranted against fading, peeling and cracking for 25 years. Unfortunately, the desired durability can never be uniform across all applications and performance failures do occur and are costly. Classic durability testing often provides misleading information. This project aims to develop a sound mechanistic model for polyester-isocyanate performance chemistry and to develop strategies for 'superdurable polyester' formulations based on these findings. This research will provide recommendations to BHP Coated Steel Australia on adoption of isocyanate based technology in the COLORBON..
