This easy-to-apply plastic coating forms a protective film around the outside of a glass component. It will normally contain both the glass particles and the materials inside the vessel should the glass vessel break during an experiment. This is a hard, adherent film and is resistant to leaching and bleed-out in a bath. The coating will withstand -20 to 121 degrees C for extended periods of time without degredation. Do not use in direct flame. Available in two size containers. Directions for applying and curing supplied.
