Features:
1.Two-component,neutral curing,odorless, non-corrosive cure system , high adhesion, high strength capacity,high displacement capacity.
2.Good compatibility with other neutral silicone sealants.
3.High displacement capacity.
4.Excellent weatherability and high resistance to ultraviolet 5.Remains flexible over a temperature range of -58°F(-50℃) to 302°F(150℃).
6. Uncured, both the A and B components are thixotropic pastes, when mixed, cure quickly to an extremely tough elastomeric silicone rubber ensuring a durable, flexible, watertight bond upon exposure to atmospheric moisture.

Main applications:   
1.Silicone structural glazing in curtain wall,structural attachment of many panel systems.
2.Protective glazing applications, panel stiffener applications.
3.Secondary seal and joint structural insulating glass.
4.Seal in the situation of high sealed security.

Limitations: 
1.Can not be used with marble, granite and other alkaline substances in contact situations.
2.Is not appropriate for all will be leaking oil, plasticizer or solvent surface.
3.Not for frost or wet surface.
4.Is not suitable for the place of continuous immersion or year-round moisture.
5.Surface temperature is not below 0℃ or above 50 ℃.
6.Can not ontact with strong acids or bases.
7.Joints where abrasion and physical abuse are likely to be encountered.
8.Hasn't reviewed shop drawings for applicability and hasn't performed adhesion and compatibility tests on project substrates, spacer materials and all accompanying accessories.

Installation:
1.Characteristic test:A structural glazing sealant should have at least its curing and adhesion characteristics periodically checked during fabrication and installation.
2.Surface preparation: Sealants may not adhere or maintain long-term adhesion to substrates if the surface is not prepared and cleaned properly before sealant application.Using proper materials and  and cleaning procedures is vital for sealant adhesion.
3.Cleaning materials:clean, fresh solvent; clean, white cloths free of lint or other lint-free wiping materials; primer (when required).
4.Cleaning procedures:Remove all loose material (such as dirt and dust), plus any oil, frost or other contaminants from the substrates to which the structural silicone will be adhered. Do not usedetergent to clean the substrate as residue may be left on the surface. Wet one rag with solvent and wipe the surface with it, then use the second rag to wipe the wet solvent from the surface before it evaporates. Change the cleaning rags frequently, as they become soiled. If cleaned areas are again exposed to rain or contaminants, the surface must be cleaned again.
5.Primers: SS631 silicone structural sealant will bond to many clean surfaces without the aid of a primer. For difficult-to-bond substrates, the use of a primer or special surface preparation should be evaluated.

Emergent Treatment:
Keep out of reach of children. Once it contacts skin or eye by accident, rinse the affected part with water for 15 minutes or turn to doctor for help immediately.

Shelf Life:
12 months from the manufacture date stored in cool & dry place below 27 ℃.

Color:

Part A (base) of SS631 silicone structural sealant is available in white, part B (curing agent) in black;Black color after mixing.

Packing/ Mix Ratio:

Packing  A component:185L,B component:18.5L;A component:18.5L,B component:300ml*7. Mix Ratio by Volume  A:B = 10:1.
