Abstract

Disclosed are PP/PE copolymer backbone based pre-manufactured thermoplastic airport signage compositions primarily applied in relatively large sections onto airport runways, taxiways, and additional paved surfaces. The composition provides alkali resistant formulations comprising at least 6 weight percent PE/PP, 20 weight percent binder resin with between 5 and 15 weight percent of a tackifier resin, between 2 and 12 weight percent titanium dioxide with an optional organic dye, wherein the intermix is at least 30 weight percent of the composition and wherein the intermix is an inorganic filler that greatly reduce or eliminate debris resistance when compared to other polymer backbone compositions.
