RiteFloat (UI 7500) is a closed cell polyurethane foam used in pontoons – both external and internal – of floating roof storage tanks. The purpose of installing the RiteFloat in pontoons is to prevent them from leaking and causing the roof to sink. RiteFloat acts as a fire retardant and provides corrosion resistance to water and hydrocarbons including crude oil, diesel, gasoline, and jet fuel. This foam may also be used in double wall tanks and vessels such as barges. Meets or exceeds Mil Spec P-21929B
