PRC Rapid Seal 901 is a rapid-cure, low-odor, high performance, fuel-resistant sealant. It has a service temperature range from -65°F (-54°C) to 302°F (150°C), with intermittent excursions up to 360°F (182°C). This material is designed for fillet sealing or other general sealing applications in chemical storage tanks where there will be exposure to a variety of organic fuels. Other uses include in the chine areas of chemical storage tanks to prevent water migration between the steel and concrete base.
The cured sealant maintains excellent elastomeric properties after prolonged exposure to various types of fuels.
PRC Rapid Seal 901 is a two-part, epoxy-cured PPG Permapol P-3.1 polythioether compound. The uncured material is a low sag, thixotropic paste, suitable for application by extrusion gun or spatula. Unlike standard polysulfide sealants, it can cure at low temperatures and is unaffected by changes in relative humidity. It cures to form a resilient sealant having excellent adhesion to properly prepared common metallic substrates.
