Henry 183 Yellow Resin Coated Glass Fabric is a woven fabric, 20 x 10 mesh, made of yarns of inert, flexible filaments of pure glass. It has a tensile strength of 75 lb/in., stability and durability, and is acid and heat resistant and will not rot or decay. The special yellow resin coating on the fabric minimizes distortion, and is compatible with asphalt and coal tar cements and coatings, emulsions, solvent-based and hot-melt types. Since the yellow color is conspicuous if not completely covered, it also aids quality workmanship.
