MF882 Two Component Silicone Sealant fbr Insulating Glass
Secondary Sealant for the Manufacturing of Insulating Glass
Application areas and parts: Suitable for sealing of insulating glass in construction, transportation, refrigeration and other industries.
MF882 is a two-component room temperature curing silicone insulating glass sealant. It has excellent weathering resistance and the curing time can be adjusted.
1. Neutral curing, no corrosion to the adhered surface
2. Fast curing, with high bond strength after curing
3. No pollution to the environment
4. Excellent high and low temperature resistance and weathering resistance
5. Good adhesion to most building materials such as glass and aluminum
