STORAGE
When stored at 8-28℃ in the original unopened containers, Except for the 9661W5 (its shelf time is 6 months), 9661 series have a usable life of 9 months from the date of production.
Special precautions must be taken to prevent moisture from contacting this material.
Containers should be kept tightly close.
APPLICATIONS
- Sealing and bonding applications where non-corrosive cure is required.
- Designed for outdoor conditions.
- Applicable to adhesive/seal of PV module, automobile lampshade, lighting lamp.
HOW TO USE
- Surface preparation. For best adhesion, the substrate surface should be clean and dry prior to application. Some solvents can be used to clean the surface.
- How to apply. Squeezing gel to the clean surface.
- Curing. 9661 is cured at room temperature by reaction with moisture in the air. Curing process takes place from the outside to the inside .A 2~4mm thick coating will be take place until 24 hours after coating (25℃,55%RH). PACKING STANDARD
