Advanced Surface Engineering Technologies for a Sustainable Defense – ASETSDefense - is a Department of Defense (DoD) initiative sponsored by the Strategic Environmental Research and Development Program (SERDP) and the Environmental Security Technology Certification Program (ESTCP). Its objective is to facilitate the implementation of new, environmentally friendly technologies for surface engineering (coatings and surface treatments) by providing ready access to background information and technical data from research, development, test, and evaluation efforts as well as the status of approvals and implementations. ASETSDefense provides defense organizations with information and assistance to improve weapons system performance and life-cycle cost while reducing or eliminating environmental safety and occupational health (ESOH) impacts from coatings and treatment processes that utilize hexavalent chromium (hex chrome, Cr6+, Cr(VI), chromate, chromic acid); coatings that contain cadmium; and coatings that contain volatile organic compounds (VOC).
