PRC Rapid Seal® 682 is a flexible high-performance sealant intended for use in chemical storage tanks where there will be exposure to a variety of chemicals such as gasoline, crude oil or ethanol.
This material is designed to be used in and around chemical storage tanks for sealing around rivets heads in steel tanks for gasoline, crude oil, ethanol or other chemical liquids. Other uses are in the chine areas of the tank to prevent water migration between the steel and concrete base. The cured sealant maintains excellent elastomeric properties after prolonged exposure to gasoline, crude oil or ethanol and water contact. It has a service temperature range from -65°F (-54°C) to 250°F (121°C).
PRC Rapid Seal® 682 is a two-part manganese dioxide cure polysulfide compound. The uncured material is a low viscosity and suitable for application by brush. It cures at room temperature to form a resilient sealant having excellent adhesion to steel and concrete.
