  • Pipe lagging cloth and composition
    Patent number: 3991247
    Abstract: Improved non-flammable, rewettable pipe lagging material is formed from woven glass fabric which has been impregnated and coated with an adhesive formulation composed of Western Bentonite clay, kaolin, sodium hexametaphosphate, and water. The woven glass fabric is initially heat treated so as to thermally desize the fabric and remove initial oil and starch sizing present on the glass yarn from which fabric is made. The fabric is then contacted with the adhesive formulation and dried to form a rewettable cloth material which is white in color having a smooth surface.
