ZQ890 Type C silica gel

ZQ890 C-type silica gel is a high-strength one-component silicone sealant that cures into an elastomer at room temperature. It is dealcoholized and has no corrosion to most materials. Has good resistance to cold and heat alternating performance, aging resistance and electrical insulation properties. Outstanding moisture-proof, shock-proof and corona-proof, and anti-leakage performance. It has good resistance to high and low temperature, and has little change in performance in the range of -50°C to 200°C. It has good adhesion to most metals and plastics.

Note: All mechanical and electrical properties are measured after curing for 7 days under the conditions of 25℃ and 55% relative humidity. The performance of each type of silica gel is subject to the actual test report.

Use process and precautions

1. Clean the surface: clean the surface of the insulator, and remove dust and oil.

2. Gluing: Use a spray gun to evenly spray the paint on the surface of the insulator.

3. Solidification: Let it solidify naturally in the air.

The curing process is a curing process from the surface to the inside. Within 24 hours (room temperature and 55% relative humidity), the glue will be cured to a depth of 2 to 4 mm. If the position is deep, especially in parts that are not easily exposed to air, The time to fully cure will be extended, and if the temperature is lower, the curing time will also be extended. Before proceeding with further processing or packaging the bonded parts, it is recommended that the user wait long enough so that the firmness and integrity of the bond will not be affected.
