Woven Fiberglass Mesh Cloth Roll This non-adhesive fiberglass roll is made of high-density fiberglass cloth through special processing, mainly used for wrapping and bonding, repairs or reinforcing corners, seams, and edges of molds or pipe winding. This fiberglass cloth tape does not contain an adhesive backing, so it usually requires epoxy, polyester or vinyl ester resin with easy saturation, which will make uniform strength in both horizontal and vertical directions. The fiberglass mesh roll has a selvage edge, this prevents fraying and unraveling of fabric the edges.
