PPG Industries' (NYSE:PPG) industrial coatings business announced that its MLP80000 primer coating meets the new U.S. MIL-DTL-32348 Type I military specification for chemical-agent-resistant powder primers.
Chemical-agent-resistant coatings (CARCs) are applied to military vehicles, such as tanks, personnel carriers and equipment transporters, and to military vehicle components, such as antennae or gun turrets. In addition to their camouflage coloring and ability to resist chemical and biological agents, CARCs feature properties that prevent infrared (IR) detection by enemy forces.
The new MIL-DTL-32348 specification for a CARC powder primer and topcoat was issued by the U.S. Army Research Laboratory in November 2010 with the intent of increasing the military's use of powder coatings on military vehicles and components.
In addition to being resistant to chemical and biological agents, CARC primers approved under MIL-DTL-32348 Type I must meet specific corrosion-resistance and intercoat-adhesion requirements. They must be able to withstand degradation by ultraviolet (UV) light, resist decontamination solutions, impart low gloss and sheen specularly, and be validated to work with military-specified exterior topcoats by meeting specific physical testing requirements.
