a. Liquid Thermoplastic Traffic Marking Paint must meet and exceed the chemical <br />composition and performance requirements of Federal Specification TT-P-1952F. <br />b. Liquid Thermoplastic Traffic Marking Paint must be environmentally friendly 100% <br />acrylic emulsion traffic paint containing less than 100 grams per liter volatile <br />organic content (VOC). <br />c. Liquid Thermoplastic Traffic Marking Paint must meet or exceed TT-P-1952F Type <br />III when tested in accordance with the following ASTM test methods: D2369, D562, <br />D2697, D3723, D2805, D711, D1210, D969, D1849, D522, D2243, D1729, D968, <br />D2486, D1394, D1640, D2244, D3335, D3718, E1347, G154. <br />d. Coverage is to be 155-180 ft. of 4-inch line per gallon at 30-35 mils wet film <br />thickness. Precautions: Both surface and ambient application temperatures shall <br />be a minimum of 507, Temperature shall not drop below 50°F within a 24 hour <br />period following application. The shelf life of the paint shall be a minimum of 18 <br />months. <br />e. The paint shall dry to a no tracking condition in no more than 6 minutes.
