PPG CR-39® Monomer for High-Quality Plastic Lenses
The One.
The Original.
Because of our long history, we are a leader in the development and production of optical monomers and
coatings. It all starts with our proprietary PPG CR-39® lens monomer. There is only one
CR-39 monomer, and it only comes from PPG.
For more than seven decades, lens wearers have relied on our 1.5 index lens material, PPG
CR-39 monomer, for outstanding optical quality and durability.
Our proprietary PPG CR-39 allyl-diglycol-carbonate (ADC) monomer combines the optics of
glass with the durability of a thermoset material. The benefits are clear. Lenses made from PPG
CR-39 monomer are scratch- resistant, lightweight, have less chromatic aberration than
polycarbonate lenses, and stand up to heat and household chemicals and cleaning products.
