Abstract
Abstract Flame retardant resin bonded articles are provided which contain normally flammable or combustible polyester resin included in a bonding composition which is highly filled with aluminum hydrate and at least about 3 per cent of a trialkyl phosphate. The bonding composition is utilized to bond spatially distributed reinforcing structures, particularly glass fibers, and can include finely divided inert siliceous particles. The bonding composition, although containing a normally flammable or combustible polyester resin, liberates non-burning products under combustion conditions. A method of reinforcing and flame retarding a panel is provided which includes applying to the surface of the panel a layer of spatially distributed reinforcing structures and the bonding composition described above.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
132 words
A FLAME RETARDANT FILLED CURABLE POLYESTER RESIN BONDING COMPOSITION WHICH AFTER CURING LIBERATES NON-BURNING PRODUCTS UNDER COMBUSTION CONDITIONS, COMPRISING A. A MIXTURE COMPRISING A NORMALLY COMBUSTIBLE CONDENSATION PRODUCT POLYESTER RESIN AND A POLYMERIZABLE VINYL MONOMER, SAID POLYESTER RESIN BEING A CONDENSATION PRODUCT OF A COMPOSITION SELECTED FROM THE GROUP CONSISTING OF UNSATURATED POLYCARBOXYLIC ACIDS AND ANHYDRIDES, AND A POLYOL, SAID MIXTURE COMPRISING FROM ABOUT 40 TO ABOUT 60 PERCENT BY WEIGHT OF THE BONDING COMPOSITION, B. ALUMINUM HYDRATE IN AN AMOUNT COMPRISING FROM ABOUT 40 TO ABOUT 50 PERCENT BY WEIGHT OF THE BONDING COMPOSITION, AND C. A TRIALKYL PHOSPHATE WHEREIN THE ALKYL GROUPS ARE SELECTED FROM THE GROUP COMPRISING OF UNSUBSTITUTED AND HALOGEN SUBSTITUTED ALKYL GROUPS, SAID TRIALKYL PHOSPHATE COMPRISING AT LEAST ABOUT 3 PERCENT BY WEIGHT OF THE BONDING COMPOSITION.
