Global Syn-Turf's TCool infill is the number one choice for keeping your artificial grass cool in dry and hot climates. TCool is a patented technology, first introduced by Global Syn-Turf in 2018. It's specifically designed to prevent turf surfaces from overheating; it's a precoat applied to artificial grass sand infill activated by adding moisture. Tested, proved, and reliable, Global Syn-Turfs, TCool keeps the temperature of turf fibers down up to 50 degrees Farenheight. TCool works on the evaporative cooling principle. The means that when sun rays hit the surface of synthetic turf, solar heat energy breaks hydrogen bonds preventing the surface temperature to rise until all moisture inside TCool particles have evaporated.
