Aikon® PC AR 2021

Hard-coated polycarbonate –

Aikon® PC AR 2021

Aikon® PC AR 2021 is an extremely lighweight clear transparent hard coated polycarbonate sheet, which offers superior impact resistance. With premium protective Momentive SilFORT AS-4000 coating, AR 2021 has higher abrasion resistance than in AR 1020 quality. Hard coated PC AR 2021 also offers very high resistance to UV-radiation and protection against yellowing and loss of translucence. The coated surfaces of polycarbonate sheet are also well protected against harmful chemicals and cleaning agents.
