Vulkem Puma Base Coat Lm Low Modulus 6 Gal Pail

6 Gallon Pail, 52.7 Deg F Flash Point, 1 Hr Touch Dry Time, Liquid, Horizontal, Cold Applied, Gray Vulkem® Commercial Sealant and Waterproofing

Vulkem® EWS is a cold-applied, waterproofing system that utilizes polyurethane-methacrylate (PUMA) technology. PUMA waterproofing systems offer superior elongation over traditional MMA/PMMA technology systems. Vulkem EWS is composed of a primer (Vulkem Primer #70) and a base coat (Vulkem BC 370 or Vulkem BC 371). All system components are cured using Vulkem EWS Initiator. Vulkem Primer #70 is a methyl-methacrylate (MMA), two-component primer for porous and non-porous substrates. Vulkem BC 370, a modified polyurethane-methacrylate (PUMA) base coat, bonds firmly to Vulkem Primer #70. It retains its integrity even if substrate movement causes hair-line cracks of up to 1/16" (1.5 mm). If cut or damaged, Vulkem BC 370 will prevent water migration between itself and the substrate. Vulkem BC 371, a modified polyurethane-methacrylate (PUMA) base coat, bonds firmly to Vulkem Primer #70. Vulkem BC 371 is a low-modulus waterproofing membrane that is used when dynamic movement and extreme service temperature ranges are anticipated. Vulkem EWS with PUMA Technology is designed to have tenacious adhesion and extreme abrasion resistance. It can provide the ability to proceed with overburden one hour after application, which expedites construction schedules.
