Abstract
There are obtained laminates of improved fire resistance comprising a substrate of reinforced phenolic resin, directly coated on at least one side thereof with a surface layer of a furan resin, and bonded to the outer surface of the furan resin a "gel-coat" of an unsaturated polyester resin, wherein the furan resin contains boron in sufficient amounts to impart an improved fire resistance to the laminates as compared to the fire resistance of the outer surface gel-coat. The boron is introduced as boric anhydride by use of a substantially anhydrous boric anhydride hardener solution to harden the furan resin.
