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.
PSX 700SG coating, the latest addition to PPG’s line of polysiloxane products, has been engineered to meet federal marine color and coating requirements for U.S. Navy and other U.S. marine vessels. According to Steve Feldman, PPG national sales director, protective coatings, North America, fleetwide application of PSX 700SG coating instead of a traditional epoxy-based coating system could save the federal government hundreds of millions of dollars in lifetime operational costs.
Since being introduced in 1994, polysiloxane coatings have become the preferred technology for many industrial, military, recreational and infrastructure applications, such as marine vessels, roller coasters, oil platforms, water tanks, bridges and smokestacks.
