Tuffak CM-2 is a polycarbonate sheet with a durable, clear coating that significantly increases the abrasion resistance of polycarbonate sheets in typical exposures such as washing operations, airborne dust and dirt, and non-abusive public contact. In addition the abrasion resistant coating significantly increases weatherability and chemical resistance of polycarbonate sheets and has essentially no affect on the physical properties of the sheet. Tuffak CM-2 sheet finds wide use in glazing applications requiring abrasion resistance and weatherability.
