Abstract: In accordance with the present invention, there is provided herein improved glass fiber dispersions for making uniform glass fiber mats by the wet-laid process. The well dispersed glass fiber compositions of this invention usually are prepared by mixing chopped glass fiber bundles in water with a small amount of an amine oxide surfactant to disperse the bundles into individual fibers. As a feature of the invention, the dispersions may be formed at relatively high glass fiber consistencies. The resultant dispersions then are used to make very high quality glass fiber mats at high rates of production.

Abstract: In accordance with the present invention, there is provided herein a method of increasing the strength of wet glass fiber mats prepared by the wet-laid process. The wet-strength of such freshly prepared glass fiber mats are improved in this invention by treating the wet mat with a dilute solution of an anionic surfactant. As a feature of the invention, the wet-strength of such mats are increased substantially so that they may be conveniently handled and transferred, even manually, for further processing, e.g. for applying binders and drying, into the finished glass fiber mat product.

Abstract: This invention relates to photographic elements having a coatable, non-photoactive protective surface of improved antistatic properties. The improvement is accomplished by incorporation into this layer of an anionic fluorocarbon surfactant which is characterized by being low molecular weight oligomers of tetrafluoroethylene. In a preferred embodiment of the invention, a gelatin surface protective layer of an X-ray film includes about 1.0-3.5% by weight, based on the gelatin solids of the layer, of oligomers of tetrafluoroethylene having a large amount of hydrophilic fluoroalkyl branching in the fluorocarbon chain.

Abstract: Decorative sheet-type covering material having both PVC and polyurethane wear layers is made by first forming a sheet of gelled foamable PVC plastisol or organosol on a substrate. A layer of nonfoamable PVC plastisol or organosol is then applied to the gelled foamable layer and gelled, but not cured. A layer of polyurethane is then applied to the gelled nonfoamable layer and the entire sheet is heated to a temperature sufficient to decompose the blowing agent in the foamable layer and cure both of the PVC layers and the polyurethane layer.

Abstract: Decorative sheet-type covering material and method for making same. The material has a substrate comprising a porous mat saturated and completely coated on both sides with foamed, flexible urethane. The substrate is made by coating one side of a porous mat with reactive urethane mixture which is then allowed to foam.
