Individual Plastic Component Water Sealing

Our main objective will be to develop and evaluate material and process to prevent moisture absorption by plastic parts at the component level during storage prior to use in building next-level assembly, during storage as spares, storage of higher levelassemblies, and while in operational use. The new coatings/sealants will have excellent moisture barrier properties, improved fire retardance and controlled coefficient of thermal expansion (CTE). Nanofillers will be used to improve permeation barrierand reduce the thermal expansion coefficient. Additives will be used to improve the adhesion and fire retardance. The developed coating/sealant will be tested by the coating of small parts by UDC. The results will be verified by an independenttest facility/subcontractor. At the end of Phase I, we will provide a report with results and conclusions, and a Phase II plan, schedule and cost estimate. This program will provide a new coating to prevent moisture absorption. The developed coating will improve the performance, lower the cost, and improve reliability of all electronic components used in Air Force systems. These coatings/sealants formicrocircuits are urgently needed throughout the commercial sector as well as in defense.
