LIMITATIONS
BAIYUN SS922 Two Parts Super Performance Silicone Structural
Sealant should not be applied:
In structural glazing applications unless Guangzhou Baiyun Technology CO.,LTD. has reviewed shop drawings for applicability and has performed
adhesion and compatibility tests on project substrates, spacer
materials and all accompanying accessories. Review and testing is
done on a project-by-project basis. No blanket approval is given by Guangzhou Baiyun Technology CO.,LTD. for structural glazing applications. Structural glazing industry
guidelines (ASTM C1401) suggest that drawings and details are to be
reviewed by all parties involved in the manufacture of an SSG
system and for each building project.
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
When surface temperatures below 10ºC (50ºF) or exceed 40ºC (104ºF)
Where painting of the sealant is required, as the paint film may
crack and peel
In below-grade applications
For use as an interior penetration fire stop sealing system
In horizontal floor joints where abrasion and physical abuse are
likely to be encountered
To frost-laden or damp surfaces
For structural adhesion on bare metals or surfaces subject to
corrosion (i.e., mill aluminum, bare steel, etc.)
For contact with strong acids or bases
To surfaces in contact with food
For continuous immersion in water
For water immersion applications.
Do not apply acid-curing (Acetoxy) silicone sealants to this
product as this may cause loss of adhesion of SS922 Two Parts
Silicone Structural Sealant to glass, and/or other substrates used
in the system.
