502 Glue is a high-strength, fast-curing instant adhesive belonging to the cyanoacrylate family. It can bond metals, plastics, wood, ceramics, rubber, and other materials firmly within seconds. 502 Glue is easy to use, cures to a transparent finish, and is widely applied in daily repairs, crafts, model assembly, and electronics component fixation. Surfaces should be clean and dry before application, and direct skin contact should be avoided.
