Product Description

Insulating Glass, Structural Glazing, Facade, Curtain Wall System

 

 

DESCRIPTION
MF883 is one component neutral cured RTV silicone structural sealant for secondary seal of insulating glass units.
♦ APPLICATIONS
MF883 is mainly applied to secondary seal of traditional insulating glass units, with butyl as its primary seal, also recommended to glazing micro insulating glass with free edge incorporated by specialty glass types like ultra-thin glass (solar glass or screen glass).

• FEATURES
• Form durable and elastic sealing layer on glass and spacer surface.
• Excellent adhesion to a wide range of substrates without primer.
• Neutral cured, no corrosion to substrates surface.
• Excellent temperature stability: -60°C to 180°C.
• Non-slump, solvent free, and no pollution to environment.

♦ APPLICATION METHODS
Surface-preparation:
The sealing joint and assembly parts must be clean, dry and free from all contamination and impurities, such as grease, dust, water logging, frost, dirties, remaining glues, assembly accessories and protective coatings.
Primer:
Adhesion test must be proceeded to confirm if primer is necessary or not. If necessary, the primer shall be applied to be a thin layer with a white cloth on the surface before applied sealant. Otherwise, apply sealant directly to clean surface of substrate.
Injection of Sealant:
Continuously extrude MF883 with a positive pressure sealant gun and fully fill it in the joints.
Tooling:
Before a skin forms, tool the sealant with light pressure to spread the sealant and make sure complete surface contact with glass and spacer.
. APPLICABLE STANDARDS

• GB 16776
• GB/T 29755

. LIMITATIONS
The product is not applicable in the following conditions:
-Single seal or primary seal of insulating glass units.
-Immersion in the water.
-Any building materials exuding grease, plasticizer or solvents, vulcanized or semi-vulcanized rubber.
-Frosted or humid surface.
-The region where atmosphere vapor is closed and cut off (as sealant is moisture curing).
-Surfaces where paints are used (generally paints cannot be adhered on surface of silicone).
-contact with food or other affiliated category.

• ATTENTIONS
• In case of contact with eyes, rinse immediately with plenty of water.
• Avoid contacting with skins for a long time, and avoid contacting with children.
• Avoid contaminating foods, medicines or cosmetics.
• Do test on adhesive property of project materials before using and refer to MSDS.
• For more information on safety use and hazards, and for safety notice which is not mentioned, please refer to relevant specification of JGJ 102.
