Tremco Vulkem 191QD Rapid Curing Interlaminary Primer

Tremco Vulkem 191QD Rapid Curing Primer

Vulkem 191QD Primer is a high-performance, one-part moisture-curing primer designed to maximize interlaminary adhesion between Tremco polyurethane waterproofing layers. This low-odour, quick-drying formula is essential when membranes have been exposed for extended periods or affected by weather events that cause the primary membrane to lose its initial tack.

Key Features & Benefits

  • Rapid Curing: Quick-drying formula minimizes project downtime.
  • Low Odour: Safer and more pleasant for applicators in confined or sensitive areas.
  • Superior Adhesion: Promotes a powerful bond between polyurethane sealant and membrane layers.
  • Single Component: Easy-to-use one-part system requires no mixing.

Common Applications

Vulkem 191QD is used as an adhesion promoter for Tremco polyurethane sealants and membranes. It is particularly effective for restorative work or when applying new layers over existing waterproofing systems that have been exposed to the elements.
