But, itâs a very different material based on a different class of acrylic chemistry.he key property required of any roof coating material is durability. Acrylic technology is widely used in exterior applications for sealants, Plexiglas R, industrial coatings, house paints, because of its durability. Durability implies resistance to the effects of UV degradation from the sun.
