About us

Dr. William Lewis, a research scientist and inventor of superhard scratch- and abrasion-resistant coatings, founded a small consulting and development company in 1990 that later became California Hardcoating Company.  Dr. Lewis perceived that silicon sol-gels had tremendous potential to increase significantly the scratch- and abrasion-resistance of polycarbonate plastics, such as Lexan®, as well as many other plastics and damage-prone materials. Moreover, he believed it was possible to bring down the costs of these coatings and make them more accessible to smaller companies and for a broader range of applications.

 In his more than thirty years of experience in the fields of organic chemistry and nanoparticle silicon-based coatings, Dr. Lewis has worked and consulted for numerous companies, including 8 years with E. I. duPont and twelve years working with aerospace windows and opthalmic lenses.  He has been a manager, director, vice president and president of various companies.  He earned his Ph.D. in Organic Chemistry from the University of California, Davis, has published numerous scientific papers and holds several patents.  Full biography.
