3mm PolyGuard Hard Polycarbonate Clear Hard Coat

Our hard-coated polycarbonate undergoes rigorous testing for O2 and water vapor transfer, meeting ASTM D6701 standards. In triplicate testing, the average water vapor transfer of a coated piece of polycarbonate was reduced by 0.5g/m^2 or 28% compared to an uncoated piece of the same substrate. During testing, the coating alone exhibited an impressive water vapor transmission rate (WVTR) of only 1.6g/m^2 per day. Choose our hard-coated polycarbonate for superior protection and durability, backed by reliable performance data.
