Product limitation

This product should not be used, applied or recommended:

  • In structural glazing applications or where the sealant is intended as an adhesive.
  • In areas where abrasion and physical abuse are encountered.
  • In totally confined spaces as the sealant requires atmospheric moisture for cure.
  • On frost-laden or damp surfaces
  • To building materials that bleed oils, plasticizers or solvents – materials such as impregnated wood, oil-based caulks, green or partially vulcanized rubber gaskets or tapes.
  • In below-grade applications
  • On substrates made of polypropylene, polyethylene, polycarbonate and poly tetrafluoroethylene.
  • Where movement capability greater than ±50% is required.
  • Where painting of the sealant is required, as the paint film may crack and peel
  • For structural adhesion on bare metals or surfaces subject to corrosion (i.e., mill aluminum, bare steel, etc.)
  • To surfaces in contact with food.
  • For use underwater or in other applications where the product will be in continuous contact with water.
