PITTSBURGH – PPG Industries’ protective and marine coatings (PMC) business is celebrating the 20th anniversary of polysiloxane coatings, for which PPG was granted the first patent on January 4, 1994.

Tim Knavish, PPG Vice President, Protective and Marine Coatings, said polysiloxane coatings have revolutionized the protective and marine coatings industry, expanding into applications such as civil infrastructure, original equipment manufacturers (OEMs), government, water and wastewater, petrochemical, offshore, rail, power generation, and wind energy.

PPG polysiloxane products, specifically the PSX® brand of coatings, have been used to coat more than one billion square feet of surface area.

In the 20 years since being introduced, PSX coatings have been refined continually to meet specific customer needs. Recent innovations include a semi-gloss version for the government marine industry, a single-component formulation for easier maintenance and a new ultra-low-VOC PSX coating.
