  • Flame-resistant microporous coatings
    Patent number: 4869953
    Abstract: Water-vapor-permeable yet waterproof coated fabrics are prepared by applying a polyurethane resin solvent solution plus flame retardent to a base fabric then immersing the coating to coagulate the resin leaving a thin, microporous coating on the fabric. An acrylic acid thickener system may be included in the resin solvent solution. The resultant microporous coated fabric has a moisture vapor transmission rate of at least 600 g/m.sup.2 /24 hours, a hydrostatic pressure resistance of at least 69 kPa and is resistant to flame.
