Application

Resin

FINOS-202 Vacuum glass silicone sealant

Features & Benefits

Two-component, with fast curing speed, suitable for industrial applications

Low modulus, with excellent mechanical properties

It has excellent adhesion properties for various substrates (including coated glass, low-emissivity glass, tempered glass, laminated glass, aluminum spacers, etc.).

The weather resistance, UV resistance, heat resistance, moisture resistance and ozone resistance are all excellent.

It has excellent resistance to extreme temperatures, and its performance remains unaffected within the temperature range of -50℃ to +150℃.

Applications

Two-layer sealing for building doors and windows, as well as curtain walls: Used in conjunction with the first layer of butyl hot-melt adhesive, it achieves double-layer sealing, enhancing air tightness and durability.

Glass curtain wall, point-supported curtain wall: Structural adhesive and sealing materials used for concealed-frame, semi-concealed-frame and all-glass curtain walls.

Transportation glass components: The second sealing process for hollow glass assembly in vehicles such as trains and cars.

Refrigeration and cold chain equipment: Sealing of insulating glass in household appliances such as refrigerators and freezers to prevent condensation and thermal bridges.

Other non-structural glass sealing: For instances where two layers of sealing are required, such as glass partitions, decorative glass, and photovoltaic glass, etc.
