I. Product Featuresand applications
F-N840 silicone gel is a low-viscosity, adhesive gel-like transparent two-component addition curing silicone gel that can cure at room temperature or be heated to cure, with the characteristic of curing faster at higher temperatures. It does not produce any by-products during the curing reaction and can be applied to the surfaces of materials such as PC (Polycarbonate), PP, ABS, PVC, and metals. It is suitable for electrical component insulation, waterproofing, and fixation. It fully complies with the EU ROHS directive.
Typical Applications
- High-xiao Filter Aluminum槽Filling and Sealing
Precision electronic component packaging
High-transparency and high-recovery requirement for potting protection of module power supplies and printed circuit boards
- Elastic silicone products manufacturing
- Manufacturing low-hardness silicone products such as chest straps, insoles, and shoulder pads.
III. Process of Use:
Before mixing, first thoroughly mix Component A and Component B in their respective containers.
Mix according to a weight ratio of A component to B component = 1:1.
3. The F-N840 can be degassed as needed. Simply mix the A and B solutions thoroughly, then place them in a vacuum container and degas for 5 minutes at 0.08 MPa before灌注 for use.
4. Maintain the corresponding curing time above the temperature specified in the pre-curing and post-curing technical parameters table. If the applied thickness is thicker, the curing time may exceed. Both room temperature and heated curing are acceptable. The curing speed of the adhesive is affected by the curing temperature, and it may take a long time to cure in winter. It is recommended to cure by heating, curing for 20 minutes at 80-100°C, and it usually takes about 8 hours to cure at room temperature.
