Question: I see many so-called “five-minute” epoxy adhesives (and sometimes ones with even shorter cure times). Are these adhesives truly strong and durable?
Answer: These adhesives are used quite widely in many industrial and consumer applications. They are usually 1:1 mix systems of adhesive and hardener that have been packaged in user-friendly packages, such as a twin syringe or cartridge. In addition, they often come with a static mixer tube, which eliminates the need to mix the two components after dispensing. (Older readers will remember the days when epoxies came in two cans or tubes, and both measuring and mixing were required.)
