ABSTRACT:
A method of preparing a composite configured to release refrigerant therefrom comprises providing a substrate material comprising polarized fibers of glass, polyamide, phenylene sulfide, carbon or graphite bonding thereon a metal compound comprising a complex compound of a polar gaseous refrigerant and a metal salt and/or a hydrated metal hydroxide and/or a metal hydroxide of a metal comprising alkali metal, alkaline earth metal, transition metal, zinc, cadmium, tin, aluminum, or two or more thereof, at a concentration of at least about 0.3 grams/cc of open substrate material volume, forming layers of the metal compound bonded substrate material, and sealing at least one layer or the exterior surface of the substrate material with a coating composition configured to prevent release of internal gaseous refrigerant therethrough at ambient temperatures and pressure and capable of penetration of gaseous refrigerant therethrough from the composite interior at temperatures causing internal gas pressures of 15% or more above exterior pressure for such refrigerant release.
