Polyester Reinforcing Fabric stitch-bonded polyester is a high quality and durable reinforcement used in roof restoration systems, repair of roof splits, and base flashing details. Typically used with asphalt emulsion and/or solvent-based cold process systems. It can also be used as a reinforcement for cements, neoprene sealants, asphalt coatings, white roof mastic and white elastomeric coatings. Stitch-bonding offers an unusual combination of high strength properties with good elongation.
