If this product is exposed to the air, it will be catalyzed and rapidly polymerized to form a solid adhesive, which is why it is known as a instant adhesive. This product is widely used for adhesion between metals, non-ferrous metals, ceramics, glass, wood, and flexible materials such as rubber products, leather shoes, soft and hard plastics, etc., or between themselves. However, for materials such as polyethylene, polypropylene, and polytetrafluoroethylene that are difficult to adhere, their surfaces need to be specially treated before they can be bonded.
