Coating composition and coated substrate

Abstract

A two-component water-based coating composition that exhibits good adherence to the surface of substrates such as polyurethane foam boards. The two-component water-based coating composition is based on acrylic urethane chemistry. Coated substrates, including polyurethane foam boards coated with the two-component water-based acrylic urethane coating composition, wall cladding systems, and building walls incorporating the coated polyurethane foam boards are also disclosed. The coated polyurethane foam boards are water resistant, mold resistant, mildew resistant, UV radiation resistant, lightweight and thermally insulative.
