Devcon Flow-Mix 5 Minute Epoxy is a two part, rapid curing, clear, general purpose epoxy. Better on rigid materials, this epoxy is useful for repairing cars, bikes, boats and more. May also be used as a metal filler and to restore rotten wood. The flow-mix nozzles automatically mixes the resin and hardener together. Apply the thoroughly mixed epoxy directly to your repair. For best results, pull plunger back slightly (1/8”) to allow air bubbles to rise to the top so that you do not push air bubbles into the Flow-Mix nozzle. To get an even flow of resin and hardener, push down evenly on the plunger. Bonds metal, wood, glass, ceramic, concrete, stone, china, and fiberglass with a tensile strength of 1,500 PSI. Water resistant, with a temperature range of -40 degrees Fahrenheit to 200 degrees Fahrenheit.
