A hardener composition can be used for a reactive resin system containing a reactive resin based on radically curable, ethylenically unsaturated compounds. The hardener composition contains a hardener for the reactive resin and a filler mixture. The filler mixture is composed of a first filler having a first average particle size d.sub.50,1 and a second filler having a second average particle size d.sub.50,2. The first average particle size d.sub.50,1 of the first filler is greater than the second average particle size d.sub.50,2 of the second filler (d.sub.50,1>d.sub.50,2). The ratio d.sub.50,1 to d.sub.50,2 (d.sub.50,1:d.sub.50,2) is in the range of 8:1 to 100:1. The filler mixture is useful, and a reaction resin system can contain the hardener composition.

Disclosed is an infill for an artificial turf field, the infill comprising: from about 40 wt. % to about 60 wt. % of a polyvinyl chloride resin; from about 5 wt. % to about 30 wt. % of a plasticizer derived from a naturally occurring source; from about 2 wt. % to about 10 wt. % of a reflective pigment; from about 0.01 wt. % to about 0.1 wt. % of a blowing agent; and from about 5 wt. % to about 30 wt. % of a filler. The infill is pelletized and maintains the temperature of an artificial turf field, when disposed throughout the artificial turf field, at a temperature about 15° F. to about 25° F. less than a temperature of a comparative artificial turf under substantially similar ambient and environmental conditions, wherein a comparative infill of the comparative artificial turf consists essentially of crumbed rubber infill.
