Novel Polymer-Based Self-Actuating Seals for Barrier-Fabric Protective Coveralls

GVD Corporation (GVD) proposes to develop a durable self-actuating seals for protective coveralls. There is a strong need for a lightweight, air-breathable garment seal design to replace the incumbent rubber/latex seal technology for protecting pilots from hypothermia in the event of water landing and ejection. GVD's exceptionally hydrophobic PTFE (polytetrafluoroethylene) coatings will be employed to produce breathable and comfortable seals that resist water influx. Notably, GVD's PTFE coatings are chemically-pure, well-adhered, and can be deposited uniformly from the vapor phase. In Phase I, GVD will screen multiple PTFE coating formulations, and test coating hydrophobicity and water barrier performance. Promising seal materials will be downselected for Phase II development. In Phase II, the most promising seal systems will be further developed and scaled-up with an eye toward commercialization.
