<p>novel, non-combustible thin coating, applied as an air-setting paint, is used to form a coherent fire-barrier on or between susceptible wood or plastic substrates, or other substances. Consisting of a paint-like slurry of three separate but compatible and mutually synergistic co-bonding systems, viz. magnesium "oxycloride" cement, plus high alumina mono-calcium aluminate cement, plus colloidal silica dispersed in dimethyl formamide (DMF), and utilizing an aqueous solution of magnesium chloride as the common hydration fluid for the two cements, the coating retains its structural integrity through prolonged exposure to flame temperatures of 2000oF. The coating acts as a thermal radiation reflector for the high radiation component of most flames, used alone, or in combination with structural reinforcing geotextiles, such as non-woven spunbonded polyester fabric or woven and non-woven fiberglass or other natural or synthetic fabrics to form a laminate.</p> |
