● 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 polytetrafluoroethylene.

● Where movement capability greater than ±35% 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
