Abstract

Hardcoats are frequently used on polycarbonates and other optical plastics to increase durability by improving scratch and abrasion resistance. The current study compares several commercially available hardcoats, both dip-coated and vacuum-deposited materials. Compatibility of the hardcoat with vacuum deposited optical coats is considered. The successive layers of optical coat and hardcoat on the polycarbonate result in non-uniform spectral content and visible fringing effects due to thickness variation and thin-film interference. Experimental results and model correlation are presented.
