Tuffak® CM-2 is designation for Tuffak® polycarbonate sheet with a durable, clear coating that significantly increases the abrasion resistance of Tuffak® sheet in typical exposures such as washing operations, airborne dust and dirt, and non-abusive public contact. In addition, the abrasion-resistant coating significantly increases the weatherability and chemical resistance of Tuffak® sheet and has essentially the same physical properties of the Tuffak® polycarbonate substrate. The effectiveness of Tuffak® CM-2 polycarbonate sheet has been established by laboratory tests and outdoor weathering. Tuffak® CM-2 sheets are coated on one or both sides and shipped with a protective masking on both sides. The sheets are supplied in a wide range of standard sizes and thicknesses in both clear and transparent tints.
