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.

Abstract: An anti-static film comprises one or more polymeric film layers having a layer of conductive, low capacitance material secured thereto. The polymeric film layer(s)may have pinholes formed therethrough. The conductive, low capacitance layer comprises one or more strands of conductive, low capacitance fiber arranged in a predetermined pattern. The polymeric film layer(s) are bonded to the conductive, low capacitance material using a polymeric layer formed from the same material as the film layers. Alternatively, the layer of conductive, low capacitance material may be omitted, with the adhesive layer being extruded onto the polymeric layer having pinholes formed therethrough. Similarly, an anti-static fabric comprises one or more layers of woven polymeric material having a layer of conductive, low capacitance material secured thereto. Alternatively, the fabric may have a polymeric layer extruded thereon in which pinholes are formed.
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.

Abstract: A slurry is molded from ceramic fibers and/or microparticles to form a soft felt mat which is impregnated with a sol prior to drying the mat. A catalyst for the sol is caused to diffuse into the mat by exposing the mat to the catalyst and subjecting the mat to a soak time during which the catalyst diffuses into the mat and causes the sol to gel. The sol-gel binder forms bonds so that the mat is dimensionally stabilized. The mat is dried to produce ceramic insulation.Ceramic insulation having a consistent microstructure and a fully gelled sol-gel binder through its entire thickness is also provided.
