Strong adhesive mainly plays the role of bonding and fixing. The following is the role of strong adhesive: 1. Bonding materials: Strong adhesive can bond different types of materials together, such as wood, metal, plastic, glass, etc. It provides a strong adhesive force, so that the bonded materials can be tightly bonded together. 2. Fixation and reinforcement: Strong adhesive can be used to fix objects or reinforce structures. It can fill gaps and hold objects firmly together, enhancing their stability and load-bearing capacity. 3. Encapsulation and sealing: the strong adhesive has good sealing performance and forms an effective sealing layer at the joints and cracks. This can prevent the infiltration of liquids, gases or dust, and improve the waterproof, dustproof and insulation properties of the material. 4.
