Two Component Silicone Potting Adhesive for Electronics (SI2225)
Features
1. SI 2225A/B is used in potting protection of varied components. It can vulcanize to deep layer. The two components have a good fluidity after mixing. You can adjust the proportion of curing agent while operating. It's primerless and bonding well with most materials. It can be used to fix the accessories and resist water, dust and leakage current.
2. Double component high clarity liquid silicone adhesive, condensation dealcoholization.
3. Low viscosity, easy to process and operate.
4. Low hardening condensation, no corrosion and unstressing.
5. Excellent insulativity and stability in high temperature.
6. Excellent bonding, good water-proof and moisture-proof.
Usage
1. Electronic and modules of automobile.
2. Power control module.
3. LED display screen.
4. LED spotlight, LED wall washer, Broad Area Linear Lights and fluorescent lamp.
Operation
1. Mixing uniformity in the packing before using.
2. Maxed A, B component as the weighing ratio of 10: 1, mixing, and injected to the protection components (or modules) which need potting directly. In order to reduce the bubbles, injected slowly along the walls of the implement...
3. Let the components sit, out of bubble by themselves, heat curing or curing in the room temperature after the bubble disappeared, need about 1-6hours.
4. About potting equipment please contact our Marketing Department

Founded in DEC. 2003, SEPUNA has been engaged in researching, manufacturing and marketing automobile sealant and adhesive for 9 years.
Since the foundation, SEPUNA Chemical has been focusing on adhesive's researching and application. Then in 2005, We acquired PUNADE technology which is from Switzerland.
Within 9 years, SEPUNA mainly develops Silicone, Polyurethane and Epoxy resin adhesives. And in the future, we will enlarge our line to Unsaturated, Natural and Acrylic Resin adhesive.
After 9 years' improvement, by the keep researching and innovation, SEPUNA is already a mature adhesive supplier with the core competitiveness.
