What is the shelf life of Lab-metal and Hi-Temp Lab-metal?
Lab-metal — two years in the factory-sealed containers. Hi-Temp Lab-metal — one year in the factory-sealed containers. Please note: you may extend the shelf life by adding a small amount of Lab-solvent to the remaining contents of the container after each use. This will prevent the product from hardening in the can. (Remember, these are air-dry products).
