Hard coat films of the type found in wide variety of applications are traditionally produced by spraying or casting solutions or emulsions onto a surface followed by evaporation of a solvent. Described is a technique to produce hard coatings on a number of film substrates which does not require the use of water or solvents. This 100% solids process can duplicate the performance of conventional wet chemistry processes at higher line speeds and therefore lower cost. The Hybrid Multi-Layer (HML) process involves vacuum deposition and curing of organic precursors on the surface of a substrate rendering the surface with anti-abrasion characteristics. This talk will outline the method and results for coating an optically clear PET film with an anti-abrasion hard coat layer.
