Permanently Seals Major Cooling System Leaks Fast

Rislone Liquid Copper Block Seal Intake and Radiator Stop Leak is a one-step copper block seal. Simply pour it into the radiator, idle the engine for 5 minutes, cool, top off with coolant, and go. Draining the cooling system is not required. It works with all types and brands of antifreeze.

Liquid copper stops leaks by forming a physical seal using organic and synthetic fibres, copper and an ionic-modified mineral. The seal forms as the coolant and product flow through the leak. A wetting agent cleans the sides of the hole/crack to prepare the surface for bonding. The first fibres catch on the side of the leak, building on each other to bridge the entire hole. The fibres then act as a sieve to trap more fibres, copper particles, and minerals to create a composite seal. The seal is cemented with liquid glass. As the temperature increases, the liquid glass hardens to make the seal permanent. (FC)
