Product limitation:
This product should not be applied:

• In 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.

• 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 SS628 Two Parts Silicone Structural Sealant to glass or other substrates used in the system.

  
  Handling and safety
  Product safety information required for safe use is not included in this document. before handling, read product and material safety data sheets and container labels for safe use, physical and health hazard information. The material safety data sheet is available from baiyun sales application engineer, or distributor, or by calling baiyun customer service.
  
  How to use
  BAIYUN SS628 Two Parts Silicone Structural Sealant, when used in structural applications, must be reviewed by BAIYUN technical service specialists.
  Complete design and installation guidelines are contained in the BAIYUN Technical Manual when using this product.
  
  Method of application
  BAIYUN SS628 Two Parts Silicone Structural Sealant should be mixed and dispensed using two-component mixing equipment, which is available from several equipment manufacturers. These mixing pumping systems are specifically designed to meter precise proportions of A base and B catalyst, in an air-free environment, and mix and dispense material at proper pressures and volumes to insure thoroughly mixed air-free material.
  BAIYUN SS628 Two Parts Silicone Structural Sealant should be mixed in a ratio from 12:1 to 14:1 base to Catalyst and Base by weight, or equivalent 9:1 to 11:1 by volume for optimal properties. At this ratio, the sealant typically exhibits a working time of 20-90 minutes.
  
  
  Health and environment information
