Product Description

MF883
Silicone Sealant for Insulating Glass
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.
