- Many other uses
- Limitations
BAI YUN SS550 Neutral 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 movement capability greater than ±12.5% 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.
