F9921 EPDM Rubber Sealant is a two component 100% EPDM product which is liquid applied and cures at ambient temperatures. It is designed for use as a heavy duty sealant to protect against water intrusion on protective enclosures; as a formed in place tank liner for chemical resistance or to create custom gaskets to seal out water and a wide range of chemicals and acids in specialized equipment.
F9921 EPDM Rubber Sealant has a convenient 1 to 1 volume mix ratio and a 3-4 hour pot life.
The EPDM Chemistry is “designed” to tolerate harsh environments – temperatures from (-60°F) -51ºC to (400°F) 204ºC. Climates from dry desert to tropical rainforests and marine; immersion in many solvents, salt, caustic and acidic solutions. The main weakness of the EPDM Chemistry is that the polymer will absorb oils, fats waxes and solvents such as Mineral Spirits. This absorption results in swelling of the polymer.
Suitable for use in extreme environments and will tolerate:
– Temperature ranges from (-60°) -51ºC to (400°F) 204ºC
– High humidity, live steam and total immersion
– High salt concentrations
– Alcohols and Polar solvents
– Many acids up to 50% concentrations
– Liquids with a pH up to 12
