PPG HI-GARD® Scratch-Resistant Coatings
Scratch resistance
for real life
PPG HI-GARD® lens coating solutions offer multiple options to provide added protection to
today’s optical materials. PPG Hi-Gard lens coating solutions provide a durable,
scratch-resistant coating on ophthalmic lenses made from plastic materials. The optical quality of plastic
lenses is maintained, and lenses coated with Hi-Gard lens coating are four to six times more
scratch- resistant than uncoated lenses. Hi-Gard lens coatings are easy
to process and can be used with standard dip and spin coating.
Hi-Gard lens coatings are available in multiple index options, as well as
corresponding primer coatings, to match and enhance the overall durability and protection of the lens
substrate. Key features include,
- Chemical resistance – resistant to acetone, isopropyl alcohol and other commonly used
eyeglass cleaners.
- Scratch resistance – exhibit lower haze gain after abrasion testing.
