ZQ898 T type silica gel

ZQ898 T-type silica gel is a general-purpose one-component silicone sealant, cured into an elastomer at room temperature, 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. Excellent high and low temperature resistance, little change in performance in the range of -50°C to 200°C, and good adhesion to most metals and plastics. It is oxime-free curing and slightly corrodes PC.

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 adhered or coated object, and remove rust, dust, oil and other contaminants.

2. Glue: Cut off the cap of the hose, squeeze the glue onto the cleaned surface to make it evenly distributed, and close the glued surface to fix it.

3. Solidification: Put the glued or sealed parts in the air and let them solidify naturally.

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 further processing or packaging the bonded parts, it is recommended that the user wait for a long enough time so that the firmness and integrity of the bond will not be affected.

Shelf life

This product is stored in a cool and dry place at 28°C, with a shelf life of 6 months.
