  • Patent number: 6239050
    Abstract: A matrix for use in a method of photocatalytically decomposing organic compounds in a fluid includes a fiber glass mat substrate carrying a photocatalytic material. The fiber glass mat is made of randomly oriented glass fibers that have been substantially filamentized and needled whereby the filaments are interlocked. Adhesion of the photocatalytic material to the substrate is provided without requiring heat cleaning of the fiber glass by controlling the organic content of the fiber glass mat to be less than 1.0 percent by weight as measured by loss on ignition. This is achieved by using sizing compositions that preferably have little or no film forming polymer content.

  • Patent number: 6177365
    Abstract: This invention relates to novel airbag coating compositions comprising at least two separate and distinct layers. The first layer (base coat), being in contact with the airbag surface, comprises a non-silicone composition of at least one coating material, provides excellent adhesion, excellent tensile strength, and lower cost than standard silicone materials. The second layer, being a coating for the first layer, provides excellent reinforcement and aging characteristics to prevent degradation of the first layer. Such a second layer (topcoat) is preferably a silicone material. This two-layer system permits excellent strength and aging properties to prevent seam combing at relatively low cost due to the inexpensive basecoat materials and the relatively low amount required for the topcoat. An airbag fabric coated with this inventive two-layer system is also contemplated within this invention.
