Glass fiber self-adhesive tape is a coated acrylic copolymer divided into different widths and lengths. The chemical properties of glass fiber are stable. It is not easy to be oxidized. Widely used in wall renovation decoration. Collapse crack repair. Holes and stone tube sheet joints. Construction materials such as gypsum board and cement can also be bonded to prevent cracks in the construction materials. In addition, the glass fiber self-adhesive tape can be compounded with other materials to enhance the toughness and tensile resistance of the composite material, thereby achieving the purpose of enhancing crack resistance. Glass fiber self-adhesive tape has good reduction resistance, good self-adhesion, uniform grid, high strength tensile strength and deformation resistance; simple and convenient operation and easy construction.
