Plastic substrates often need hardcoating in order to improve the surface hardness and to enable additional thin-film coatings on top. Materion Balzers Optics offers different types of hardcoating solutions depending on the application and the substrate type (e.g. PMMA, PC, COC). The hardcoating solutions developed by Materion Balzers Optics are optimized for dielectric and metallic top coating and meet the harsh environmental requirements of different industries.
