  • UL Listed & FM Approved
  • Made in the USA
  • Provides the required conductivity per ASTM D8231-19 for valid ELD testing on conventional roof assemblies, including black EPDM
  • Compatible with high voltage and low voltage ELD methods
  • Chemically and mechanically compatible with fully-adhered, mechanically attached and torch-down membrane systems
  • Less than 30-minute dry time under normal conditions
  • Retesting can be performed for the life of the membrane, should a breach occur at a later date
  • Non-reflective, flat black to ensure complete coverage
  • Water-based (non-flammable & solvent-free)
  • Low VOC, meets Southern California’s strict emissions control requirements for primers
  • Roll, spray, or pre-apply to cover boards, insulation or wood
  • Easily applied to transitions and details where other conductive mediums cannot be used
  • Each 5 gallon pail covers approximately 1250 square feet on most common roofing coverboards.  Porous substrates such as wood reduces the coverage rate
