Coated acrylic –

Aikon® PMMA AR 3013/3023

Aikon® PMMA AR 3013 and AR 3023 are clear hard coated extruded acrylic sheets. AR 3013 PMMA sheet is hard coated from one side and AR 3023 is hard coated from both sides with Momentive SilFORT PHC XH100P coating agent. By its nature, PMMA sheet is very resistant to UV-radiation as well as abrasion, which extends the service life in outdoor applications. The material also shows a very high light transmission value and optical quality without any distortions. Hard coating improves the resistance to UV radiation of PMMA sheets even further and at the same time giving the material a good resistance to chemicals.
