product description
One-component room temperature curing silicone adhesive sealing material: white non-flowing fluid, good leveling performance, no penetration into small gaps, high sealing strength; after curing, the rubber compound is an elastomer, with excellent resistance to cold and heat changes and stress resistance Change and other properties; high and low temperature resistance, long-term elasticity and stability at -60~200C, anti-ultraviolet, anti-oxidation; excellent insulation, moisture resistance, shock resistance, corona resistance, anti-leakage and chemical resistance properties; fully in line with the EU rohs instruction requirements
use
It is suitable for waterproof and moisture-proof sealing of electronic components and various instruments, and can also be used for bonding and reinforcement of electronic components and potting protection of modules.
Instructions
Clean the surface: Clean the surface of the object to be glued to remove rust, dust and oil.
Glue application: Use a blade to cut off the front tip, put on the tip, squeeze the glue onto the cleaned surface with a squeezing gun, make it evenly distributed, and close the glued surface to fix it.
Curing: Place the glued or sealed parts in the air and let them cure naturally. The curing process is a curing process from the surface to the inside. Within 24 hours (room temperature and 60% relative temperature), the glue will be cured to a depth of 3~5mm. The curing time 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, the user is advised to wait long enough so that the firmness and integrity of the bond is not compromised.
Precautions
After the operation is completed, the unused glue should be tightened immediately and the cap should be tightly sealed. When using it again, if there is a little crust on the seal, just remove it, it will not affect the normal use. During the storage process of the glue, there may be a small amount of curing phenomenon at the mouth of the nozzle. After removing it, it can be used normally without affecting the performance of the product.
