Polyurethane Finishes are high-performance protective topcoats formulated as two component aliphatic acrylic polyurethane systems. These finishes are available in high solids and high build versions, providing excellent durability, UV resistance, gloss retention, and weathering resistance. Two component high solids polymeric urethane finishes deliver a smooth, long-lasting aesthetic finish and are widely used in industrial, infrastructure, marine, and offshore environments.
