Methods and systems for providing a communication path are disclosed. Unique valves formed in part by flexible material reduces the likelihood of fatigue and increases efficiency by retaining less heat relative to conventional reed valves. The aqueous treatment bath contains a urea resin, polytetrafluorethylene and, preferably, fluoroalkyl acrylate co-polymer. The pins are positioned at an angular disposition with respect to the first and second supports for retaining the first support in a desired position. The mixture can be washed off a bum victim with soap and water.
