EPDM Rubber

Both liquid EPDM products come as a two-part system, mixed just before application and has a pot life (remains liquid) for 4 – 6 hours.
NOTE: Liquid EPDM will not cure below 55ºF – however…
If the temperature drops below 55ºF after the product has been applied, the curing will stop. This will not harm the product. When the temperature rises above 55ºF the curing will continue.
Curing to tack-free will occur in 18 – 24 hours if the temperature is 70ºF. Lower temperatures take longer and higher temperature will shorten the cure time. Full cure in 3-7 days. Liquid EPDM can also be used over concrete and wood.
When liquid EPDM rubber cures to EPDM membrane its characteristics include outstanding resistance to weathering, ozone and UV exposure, excellent color stability and heat resistance. It offers many of the advantages of rubber at a lower cost. It’s temperature range, -60ºF (used in freezer gaskets) to 300ºF (used in automotive radiator hoses) make it an ideal roofing material. EPDM is a non-oil resistant film.
What is EPDM rubber?
EPDM (Ethylene Propylene Diene Monomer) is a synthetic rubber–a highly flexible stable material. It has excellent resistance to ozone and many other advanced chemicals found in today’s environment. EPDM’s balance of physical properties and chemical resistance makes it ideal for a wide variety of rubber applications, especially roofs.
