ULT-TAC is a high performance tackifier and the key ingredient in creating a bonded fiber matrix slurry. Ult-Tac works great with any hydro mulch and it mixes quickly into the slurry. Ult-Tac combines the characteristics of an organic guar based tackifier and the mechanical bonding of the long strand Mechanical Fibers to thicken and hold fiber mulch in place on the steepest of slopes. It creates a stabilized fiber matrix material when added to fiber mulch at a fraction of the cost compared to other spray-on erosion control products.
