3. PRODUCT DESCRIPTION
T272, T325 and T326 are 100% polyester stitch-bonded fabrics made without the use of adhesives. They provide outstanding physical strength, unique elongation, quick wet-out and saturation, and ease of application.
T272 is especially suited to reinforcing acrylic elastomeric roof membranes, while T325 and T326 have weave patterns better suited to reinforcing thicker applications of asphalt emulsion that provide waterproofing beneath an acrylic top coating.
