Polysiloxane Products News

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 Jan. 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 Industries’ (NYSE: PPG) protective and marine coatings (PMC) business has published a white paper comparing the performance of polysiloxane coatings to that of traditional epoxy/urethane and epoxy/silicone-alkyd coatings. The four-page white paper summarizes polysiloxane coatings chemistry and explains how it enables PPG products such as PSX(R) 700 and PSX 700SG (semi-gloss) coatings to provide long-term color and gloss retention as well as chemical and corrosion resistance that outperform traditional epoxy-based coatings. It also explains that the molecular structure of polysiloxane coatings makes them safer for people and the environment because they emit low volatile organic compounds (VOCs) and are made without isocyanates, which are suspected carcinogens.
