Service Bulletin | Due to recent improvements in both the Liquid Roof and Liquid Rubber we have improved the cure time greatly. By doing this we have noticed a shorter pot life after the catalyst is incorporated into the base material. Once the catalyst is added the reaction period begins. The working time to apply Liquid Rubber and Liquid Roof is between two hours and four hours depending on the temperature. The higher the temperature the shorter the working time. Once the catalyst is mixed into the EPDM it must be used. Pro Guard does not warrant catalyzed product that is not used within the proper time frame.
Our Moisture Cure Liquid Rubber is a Silylated Hybrid Polymer based on a Urethane/Polyether chemistry. This innovative Polymer combination and treatment results in a unique combination of properties:
Add the pre-measured catalyst and apply by brush, roller or spray. The resting viscosity is slightly thick but this will reduce when agitated. Product should be able to be sprayed without solvent dilution. Substrate to be coated may be damp but should not have water droplets on it.
