PACKAGING
BAIYUN SS850 General Purpose Silicone Sealant is available in 10.1 fl. oz. (300 ml) plastic caulking cartridges and 16.9 fl. oz. (500 ml) foil sausage packs
USABLE LIFE AND STORAGE
When stored at or below 27ºC (80ºF) in the original unopened containers, BAIYUN SS850 General Purpose Silicone Sealant has a usable life of 12 months from the date of manufacture.
LIMITATIONS
BAIYUN SS850 General Purpose 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 substrates made of PP, PE, PC, PMMA and PTFE.
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.
New concrete must be allowed to cure and dry for at least 7 days of good drying weather.
