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 to remove rust, dust, oil and other contaminants.
2. Glue: Unscrew (or 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: Place 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 glue position is deep, especially the parts that are not easily exposed to air, The curing time will be extended. If the temperature is lower, the curing time will also be extended. It takes more than 7 days for the 6mm thick sealant to fully cure.
4. After the operation is completed, the unused glue should be tightened immediately and sealed and stored. When using it again, if there is a little skin on the seal, just remove it, and normal use will not be affected. During the storage of the glue, a small amount of solidification may also occur at the mouth of the tube. After it is removed, it can be used normally without affecting product performance. If you accidentally get into your eyes before curing, seek medical attention.
