Hartco uses a specially formulated high tack polymer that by its nature retains a tacky surface over a long period of time under heavy use and multiple cleanings. The surface of the mats and flooring are smooth and flexible allowing the mats to entrap the contamination until cleaned. These characteristics not only allow the mat to pick up 100% of the footborne and wheelborne contamination but do not allow it to be tracked off the mats and flooring.
