4oz fiberglass clothis a kind of polymer anti-emulsion impregnated coating based on glass fiber woven fabric. It is widely used in wall reinforcing materials, reinforced cement products, reinforced plastics, rubber products, etc., many of my friends are using 4oz fiberglass cloth, but how can you tell the difference between good and bad? Today we share how 4oz fiberglass cloth separates the good from the bad.

Method 1: Look at the 4oz fiberglass cloth to see if it is good or bad. The better quality 4oz fiberglass cloth has a clean surface, even and straight warp and weft lines, good toughness, and even mesh. 4oz fiberglass cloth, on the other hand, is of poor quality, with uneven grids and poor toughness.

Method 2: The 4oz fiberglass cloth chemical property is relatively stable, resistant to alkali, acid, water, cement, and other chemical corrosion, and it is safe to use.

Method 3: To judge the quality of 4oz fiberglass cloth by its color. The better quality 4oz fiberglass cloth has shiny and uniform color, while the worse quality 4oz fiberglass cloth is not only prickly to touch, the color is dark and cloudy.

Method 4: Judge the quality of 4oz fiberglass cloth by stretching it. A good 4oz fiberglass cloth is not easy to deform and can be recovered by stretching, whereas a poor quality 4oz fiberglass cloth is difficult to recover from the deformation and affects normal use.
