LIMITATIONS

SS821 Silicone Structural Sealant should not be used, applied or recommended:

ŸIn structural glazing applications unless Guangzhou Baiyun Chemical Industry 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 Chemical Industry 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.

ŸTo building materials that bleed oils, plasticizers or solvents – materials such as impregnated wood, oil-based caulks, green or partially vulcanized rubber gaskets or tapes

ŸIn totally confined spaces as the sealant requires atmospheric moisture for curing

ŸWhen surface temperatures below 10ºC (50ºF) or exceed 40ºC (104ºF)

ŸWhere painting of the sealant is required, as the paint film may crack and peel

ŸIn below-grade applications

ŸFor use as an interior penetration fire stop sealing system

ŸIn horizontal floor joints where abrasion and physical abuse are likely to be encountered

ŸTo frost-laden or damp surfaces

ŸFor structural adhesion on bare metals or surfaces subject to corrosion (i.e., mill aluminum, bare steel, etc.)

ŸFor contact with strong acids or bases

ŸTo surfaces in contact with food

ŸFor continuous immersion in water

ŸThis product is neither tested nor represented as suitable for medical or pharmaceutical uses.
