Abstract

The weathering resistance of an exterior coating is one of the main properties required by the end-user. The backbone structure of several monomers and oligomers has been investigated and subjected to accelerated outdoor weathering testing (Q-Trac)and correlated with actual Florida exposure. The performance of these products has also been compared to a standard 2 component urethane intended automotive topcoat applications. The physical properties including yellowing resistance and gloss retention will be presented. This ongoing study has shown that these acrylates, which are free from light stabilizers, can withstand three years of Florida exposure without degradation. Since the testing was conducted in accordance with automotive test standards, these products are suitable for any application requiring superior outdoor durability.
