Versatile Liquid Crystal Tunable Interference Filter for Chromosome Analysis

Not Available Solvent-based primers and topcoats have been used as the primary aircraft coating systems. For corrosion protection, highly toxic heavy-metal based corrosion inhibitors were used and are still present in many of the most popular primers. With the environmental compliance regulations getting more and more strict, the cost of aircraft painting/stripping/repainting processes and waste disposal have become very expensive for the Air Force. In the new Air Force Coating System Strategy, both environmental compliance and long-term coating system performance are to be fulfilled with development of new advanced coating systems. This proposal involves with the research of two areas: 1) Low/no VOC matte coating systems that will lead to highly durable, rain and dust erosion resistant and weatherable coatings, and 2) Polymeric sprayable/rollable environmentally robust 30+ years primer materials. The contractor proposes to develop low VOC or water-based corrosion resistant epoxy primers and low VOC or water-based erosion resistant urethane topcoats. Corrosion inhibitors and special matting agents will be evaluated. Rain erosion tests will be conducted. Among materials to be tried are new erosion resistant urethane coatings developed by this contractor for helicopter rotor blade applications and other new coating chemistries.
