Product Details

PPG PRC Rapid Seal 652 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 seal fixed and floating roof systems in and around chemical storage tanks. Other uses are in the chine areas of the tanks 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 652 is a two-part manganese dioxide cured polysulfide compound. The uncured material is a low-sag, thixotropic paste suitable for application by extrusion gun or spatula. The material can be applied to most typical vertical or overhead joints without sagging. It cures at room temperature to form a resilient sealant having excellent adhesion to steel and concrete.
