Abstract:
An example composition includes a cloth, which has on each side thereof, a first waterproofing agent, a barrier which inhibits or prevents environmental degradation, and an elastomeric barrier including a second waterproofing agent. Another example composition includes a cloth with a phenolic resin coating having, on each side thereof, a first waterproofing agent, a barrier which inhibits or prevents environmental degradation, and an elastomeric barrier including a second waterproofing agent.
Abstract:
A process for the impregnation of non-living-materials comprises the step of impregnating the non-living material with an aqueous formulation free of organic solvents which comprises one or more pesticides and a polymeric binder comprising one or more fluorinated polyacrylates having a fluorine content (based on the solid content of the polymeric binder) of at least 10% by weight.
Abstract:

Abstract:
The present disclosure provides an acoustical substrate including nonwoven material which includes a two component adhesive system which may be treated with a fluid repelling compound. The two component adhesive system may comprise two adhesive components having different melting points to allow for flexible industrial post processing and laminating. The adhesives may be applied by a variety of methods and may exist in the substrate in, e.g., either discrete or continuous web forms.
Abstract:
The invention relates to a water repellent, electrically conductive composite comprising an electrically conductive fabric comprising a first upper surface and a second lower surface, wherein the first upper surface opposes the second lower surface, a hydrophobic coating overlaying at least the first upper surface and second lower surface of the conductive fabric thereby forming a hydrophobic coated fabric, and barrier layers on the hydrophobic coated fabric such that the barrier layers form the outer surfaces of the water repellent, electrically conductive composite, and wherein the barrier layers are electrically insulating and water and water-vapor impermeable.
Abstract:
A method of making fabrics having first and second surfaces that exhibit different performance characteristics by virtue of having treated with different chemical treatments is described. In addition , fabrics having first and second surfaces that exhibit different performance characteristics, such as one surface exhibiting oil and water repellency and optionally, soil release characteristics, and the opposite surface exhibits moisture transport characteristics.
Abstract:
The invention relates to a method for preparing a moisture barrier fabric comprising needling the fabric in a direction substantially opposite to the advance direction of the fabric with barbed needles to increase the density of the fabric by entangling the fibers thereof, open-width washing of the needled facecloth fabric with a detergent and sodium carbonate to further increase fabric density by allowing the fabric to neck down or bulk at a substantially random rate, coating one side of the fabric with at least one coating of a latex formulation for use in forming the backcoating of the moisture barrier fabric, comprising a (meth)acrylic acid urethane copolymer having a curing temperature of approximately 250 to 275 °F, and immersing the dry moisture barrier fabric, including the latex backing, into a bath of fluorochemical and a solution containing about 10 to about 15 wt% polyurethane, and removing excess fluorochemical from the treated fabric.
Abstract:
The present invention provides coating materials (14), insulation-containing building material products bearing the materials and methods for applying the coatings to the building material products. The coating materials (14) possess one-way "breathability" c haracteristics with respect to water and aqueous solutions. That is, the coatings are essentially impermeable to liquid water and permeable to water vapor. Vapor from water insulation coated by the material may thus pass through the coating, whereas liquid water is effectively prevented from passing through the coating and entering the insulation.
Abstract:
A process for coating a perforated substrate with a gel (e.g. a polymerised acrylate hydrogel or a xerogel) without substantial occlusion of the perforations comprises (i) forming a layer of a liquid pregel mixture, comprising one or more monomers, on a web coated with a silicone, polyethylene, Teflon (R) or other coating having a surface energy less than the surface energy of the liquid pregel mixture; (ii) contacting the perforated substrate with the liquid pregel mixture; and (iii) curing the liquid pregel mixture. Preferably at least part of the curing takes place while the liquid pregel mixture is in contact with both the perforated substrate and the web. The process is especially applicable to the manufacture of attachment tabs for wigs and toupees, wound dressings, patches for transdermal drug delivery, therapeutic patches or biomedical skin electrodes.
