Limatations

Finos FNS901 Flame resistant silicone sealant 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 concrete and cement substrates.
On substrates made of polypropylene, polyethylene, polycarbonate and polytetrafluoroethylene.
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
