  • Publication number: 20090104425
    Abstract: A fire retardant coating composition for a fibrous mat comprises one or more fillers and one or more binders with each organic binder having a peak heat release rate of ?1000 kW/m2 as measured by ASTM E1354, flux 30 kW/m2. A coated fiberglass mat comprising the coating composition has a FIGRA value of ?120 W/s according to EN 13823, 0.4 MJ and a flame index of ?25 and a smoke index of ?50 according to ASTM E84.

  • Publication number: 20090075541
    Abstract: Provided is a coated nonwoven mat prepared by the process of passing a nonwoven mat over the surface of a binder or coating slurry to touch the bottom side of the mat sufficiently to fully wet the glass mat. The wetted nonwoven mat is then immersed in a slurry of the binder or coating material to fully saturate the mat with the slurry material. The process of the present invention allows one to control the porosity of the saturated fibrous nonwoven mat at high consistency with reduced scrap rate. The saturated mat will have improved tensile strength.
