DL8283A Da-Lite Polacoat rear projection screen consists of a specially formulated optical coating, designed to provide the highest resolution and most accurate color fidelity. This coating is deposited on a transparent glass (Da-Glas) or acrylic (Da-Plex) substrate. Da-Lite utilizes a special coating process which chemically bonds the optical layer to the substrate, creating a very high degree of adhesion guaranteed not to peel or strip off.
