Tremco Vulkem EWS with PUMA Technology

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 system that utilizes polyurethane- methacrylate (PUMA) technology. Vulkem EWS is composed of a primer (Tremco PUMA Primer), a base coat (Tremco PUMA BC), an intermediate wear coat (Tremco PUMA WC) and a top coat (Tremco PUMA TC). All system components are cured using Tremco PUMA Initiator.

Tremco PUMA Primer is a methyl-methacrylate (MMA), two-component primer for porous and non-porous substrates. Tremco PUMA BC is a modified polyurethane-methacrylate (PUMA) base coat. Tremco PUMA BC bonds firmly to Tremco PUMA Primer. It retains its integrity even if substrate movement causes hair-line cracks of up to 1/16″” (1.5 mm). If cut or damaged, Tremco PUMA BC will prevent water migration between itself and the substrate.

Tremco PUMA WC is a modified polyurethane-methacrylate (PUMA) wear coat. Tremco PUMA WC is applied after Tremco PUMA BC has cured. The wear coat is loaded with aggregate to give the system excellent impact, abrasion and chemical resistance. Tremco PUMA TC is a methyl- methacrylate (MMA) top coat. Interlaminary adhesion to Tremco PUMA TC is exceedingly strong. The top coat affords excellent abrasion resistance, UV stability and chemical resistance to complete the Vulkem EWS.

Basic Uses

Vulkem EWS is a cold-applied traffic deck coating system designed for waterproofing concrete slabs and protecting occupied areas underneath from water damage. Additionally, the system will protect the concrete from the damaging effects of chloride, deicing salts, chemicals, gasoline, oils and anti- freeze. The Vehicular System is ideal for ramps, helical turns and ticket splitters.

Features and Benefits
Polyurethane-methacrylate (PUMA) technology delivers extreme durability while maintaining its crack-bridging characteristics.
Rapid set-up times allow for quick overall installation, as well as the ability to open up to foot traffic one hour later.
Can be applied at temperatures below 20 °F, which allows for continuation of projects in the colder months.
Initiator adjustments allow for 30 to 45 min cure time between applications, even at temperatures below freezing.
Compatible with Tremco sealants and coatings, which is essential for tie-ins, detailing and penetrations.
Extremely forgiving application allows users to apply additional coats long after the previous coat has cured.
Unique chemistry allows for easy repair.
