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.

Moisture Cure Liquid Rubber 9101

Product Description

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:

  • Coating cures in 1–3 hours by absorbing moisture from the air
  • Film is elastomeric with high elongation
  • Good adhesion to most substrates except TPO and PVC membrane
  • Can be applied to a damp surface
  • Withstands ponding water and total immersion
  • Easily recoatable without a primer
  • Cures at low temperatures
  • Ultra Violet stable
  • Tolerates low temperatures to minus 50˚F
  • Can be sprayed without diluting
  • Has very good in-can stability until catalyst is added
  • Will adhere to a fully cured film of Pro Flex Primer
  • Coating is oil resistant so it can be used on restaurant roofs
  • This product contains NO Isocyanates

Application

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.
