Vulkem® EWS with PUMA technology is designed to have tenacious adhesion and extreme abrasion resistance. It can be walked on in one hour, which will minimize operation disruption. Vulkem Extreme Wearing System (EWS) is a waterproof traffic deck coating that utilizes polyurethane-methacrylate (PUMA) technology. Vulkem EWS is composed of a primer (Tremco PUMA Primer), a base coat (Tremco PUMA BC), and a top coat (Tremco PUMA TC). All system components are cured using Tremco PUMA Initiator.
Vulkem EWS can be applied down to 20 oF/ -7 oC. Below this temperature, the Tremco PUMA Cold Weather Catalyst must be used.
Concrete shall be water cured and attain a 4000 PSI minimum compressive strength. All soncrete shall be shotblast to a ICRI CSP #3-#4 finish. Moisture content in the concrete must be lower than 6% as measured using a Tramex CME 4 Moisture Meter. Depending on concrete construction and job site location, additional concrete testing may be required. Please contact your local Tremco Sales or Technical Representative.
No. Traditional constructions solvents such as xylene, mineral spirits, acetone, isopropyl alcohol, etc cannot be used with Vulkem EWS. All cleaning of tools and coating must be done with Tremco PUMA Cleaner.
No. Vulkem EWS components contain both polyurethane methacrylate and methyl methacrylate. While these ingredients carry a distinct odor, neither are harmful. In fact, the chemical makeup is almost identical to acrylics used in nail salons.
Each layer of the Vulkem EWS system cures in 30-45 minutes and the next coat can be applied at that time. In fact, Vulkem EWS can be opened up to traffic one hour after installation is complete. Please contact your local Tremco Sales or Technical Representative when choosing the appropriate system (Heavy Duty, Vehicular, or Pedestrian) for your application.
