*The thickness of the cured sample is approximately 2mm. It is cured for 7 days under the conditions of (23±2)°C and (50±5)% relative humidity (RH), with a testing temperature of 23°C.



Instructions:

 

1. For optimal performance, the bonding surface should be cleaned of any grease and dust. A specialized cleaning agent, such as a titanium-based cleaner, can be used to clean the bonding interface.

2. Before opening the container, it is recommended to allow the product to reach room temperature to prevent condensation, which may affect product performance.

3. When manually applying the adhesive, cut the nozzle to the appropriate size as required, and load it into a handheld manual or pneumatic caulking gun. Apply a sufficient amount of silicone evenly on one mating surface to ensure a continuous and closed bead of adhesive. If using automated equipment for application, set the equipment parameters appropriately for uniform and continuous coating.

4. After applying the adhesive, immediately assemble the two bonded parts together. Any excess adhesive squeezed out can be easily wiped away with a cloth.

5. Once the original packaging is opened, it is recommended to use the entire contents at once. If not used completely, remove the cured portion before continuing to use.



 


Storage/ Shelf Life/Packaging

 

The shelf life is 12 months when properly stored in a cool, dry area in unopened containers, temperature 5~28℃.
