Aikon® PMMA AR 4023

Coated acrylic –

Aikon® PMMA AR 4023

Aikon® PMMA AR 4023 is a clear hard coated cast acrylic sheet. By nature, PMMA sheet is resistant to abrasion as well as UV-radiation, which translates to an extended lifetime in outdoor applications. The material also shows very high light transmission value and optical quality without any distortions. Combined with Momentive SilFORT PHC XH100P hard coating gives PMMA sheet improved UV radiation and very good chemical resistance.
