Ready to use and specifically developed for the emergency sealing of leaks from holes, tears and ruptures. A water-based gel containing a food-grade clay, a recycled polymeric reinforcing agent and a low toxicity freezing point depressant. Applied directly over the leak to form an immediate seal. Good resistance to water, oil and a wide range of chemicals over short-term exposure (1-5hrs), and in many cases for at least 24 hrs. Full details available on request.
