Structural adhesive. Structural adhesive has the advantages of high strength, simple use and aging resistance. When using this structural adhesive, it is best to coat it with a thin film, and the thin layer has the best effect. The drying speed is fast, and the layer thickness will affect its drying speed. As long as it is evenly coated, clean the coated surface first, and then clean the plastic sheets and windows. After applying, keep your hands still for a few seconds, and then release them. After the structural adhesive is used up, it must be sealed and placed in a cool place to avoid sunlight, otherwise the adhesive will slowly dry and solidify.
