Traditional military coating systems formulated with Volatile Organic Compounds VOCs and Hazardous Air Pollutants HAPs burden the Air Force and other DoD agencies with environmental compliance, permitting, tracking, storage, operations, disposal, and reporting requirements. In addition, the handling and disposal of toxic hazardous wastes associated with the removal and reapplication of the hexavalent chromium containing primers in traditional coating systems is costly, time consuming, and represents a risk to health, safety, and the environment. Powder coatings represent a mature technology that eliminates the hazardous waste streams e.g., air emissions, contaminated booth filters, unused admixed paints and cleaning solvents associated with conventional wet painting operations. Additionally, use of powder coatings also reduces employee exposure and liabilities associated with wet painting. Advantages over conventional wet painting include greater coating durability, elimination of VOCs and HAPs, improved transfer efficiency, and the elimination of drips, runs, and blistering defects. Low temperature powder coatings LTPC offer the advantage of reduced energy consumption by being able to process at lower temperatures.
