INFILL COATED WITH A POLYURETHANE PREPOLYMER AND ARTIFICIAL TURF SURFACES INCLUDING THE SAME
In various embodiments, coated infill includes a plurality of infill granules and a preformed coating on the infill granules including a cured polyurethane product of at least one polyurethane prepolymer component and a curative component. The polyurethane prepolymer component includes a reaction product of an isocyanate component including diphenylmethane diisocyanate (MDI) and a polyol component, and has a free isocyanate content (% NCO) from 2 wt % to 12 wt %. The curative component includes water. Methods for making an artificial turf surface using the coated infill are also provided.
