Vapor Phase Testing using Gas Chromatography - Mass Spectrometry
We asked Envantage Testing Labs to put GRIP-FLEX Surfacing through a rigorous testing process to determine just what, if any PAH components might be released during the curing process.
GRIP-FLEX Surfacing is applied at ambient temperature, with 50 Degrees Fahrenheit the minimum and 120 Degrees Fahrenheit being the maximum likely temperature encountered in the actual project environment. So we had the lab test GRIP-FLEX at 50, 80 and 120 Degrees F.
Of course, since we use a very highly refined coal tar we knew that our material was free from harmful vapors, but since there is such a smear campaign being mounted on the coal tar industry we thought we'd take the initiative and have the test results published for all to see.
