Introduction:
The SS658 silicone structural sealant is specifically designed for bonding and
sealing applications in areas such as curtain wall assembly, furniture manufacturing, and unitized panels. This 1:1 dual-cartridge, alkoxy, two-component structural sealant
combines the rapid curing speed of two-component adhesives with the ease of
application typical of cartridge-based adhesives. Before using, the A and B
components are mixed thoroughly with a caulking gun and mixer, then extruded into
the areas to be bonded and sealed. After curing, it transforms into an elastomer, creating an effective seal.

Features:

 Two-component, alkoxy, neutral curing, non-corrosive to metal, coated glass, concrete and marble.

 Non-corrosive curing system.

 No unpleasant odor during curing.

 Excellent weather ability and high resistance to ultraviolet radiation, heat and humidity, ozone and temperature extremes.

 Remains flexible over a temperature range of -58 ºF (-50℃) to 302 ºF (150℃)  Good compatibility with other neutral silicone sealants.

Composition:
 Two-part, neutral-curing
 RTV silicone sealant
Applications:

 Structural bonding and sealing of glass, aluminum curtain wall, glass lighting
roof and metal structure works.

 Home decoration moving doors, porcelain plates, decorative plates, etc., need fast
curing bond seal.

 In the field of building photovoltaic, fast bonding and sealing of roofing photovoltaic metal parts.

Product limitation:
This product 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 partiesinvolved 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 SS658 Silicone Structural Sealant to glass or other substrates used
in the system.
