Liquid Roof® is a true EPDM rubber and therefore could be described as a liquid version of the single ply EPDM membrane that has established an outstanding performance record for over 30 years. The EPDM chemistry has two unique features not possessed by any other rubber: It is unaffected by ultraviolet and ozone, and can tolerate continuous exposure at temperatures over 300 Degree Fahrenheit. This feature is what gives EPDM rubbers the best aging properties (retain flexibility longer) of all the elastomers.PROP 65 WARNING: This product may contain chemicals known to the State of California to cause cancer and birth defects or other reproductive harm.
