ABSTRACT:
A glass fiber mat contains between 68% and 90% glass fibers and between 10% and 32% binder by weight of the mat. The binder contains between 2% and 90% polymer modified asphalt and between 10% and 98% thermosetting resin by weight of the binder. The polymer which modifies the asphalt is selected from thermoplastic and/or thermoset polymers. A preferred thermoplastic polymer is selected from reactive thermoplastic polymers and/or thermoplastic elastomers. The binder is preferably applied to the glass fibers in the form of a blend of thermosetting resin and an aqueous emulsion of polymer modified asphalt. The aqueous emulsion is prepared by combining between 5% and 75% asphalt, between 2% and 20% polymer selected from thermoplastic and/or thermoset polymers, between 25% and 95% water, and between 0.5% and 5% surfactant by weight of the aqueous emulsion.
