The sealant does not cure for a long time because the product has expired, the storage environment is inappropriate, and the sealant is affected by the surrounding environment during the curing process. The first two factors can be achieved as long as we pay a little attention, so how should we avoid the third factor?
Characteristics of bonding sealants:
Adhesive sealants are insulating, moisture-proof, dust-proof, mildew-proof, shock-proof, leakage-proof, corona-proof, corrosion-proof, salt-spray-proof, acid-alkali-proof, vulcanization-proof, aging-proof, high and low temperature impact resistance, and high humidity resistance It has superior environmental performance such as high temperature and flame retardancy.
Uses of bonding sealants:
Widely used in new energy, military, medical, aviation, shipbuilding, electronics, automobiles, instruments, power supplies, high-speed rail and other industries.
If you want the sealant to cure well, you should pay attention to the following points:
1. If the amount used is small, it is best to buy a small amount of adhesive and do not open a large bottle at one time. The remaining part is not easy to store and the storage conditions are strict.
2. When applying sealant, choose the appropriate ambient humidity and temperature. You can ask the purchaser for details.
3. When the temperature of the gluing environment is too low, it is recommended to cure the adhesive at high temperature when curing, such as high-temperature baking in an oven.
4. Before applying glue, clean the surface of the material and keep it dry. Do not use it immediately after curing. You can wait for a period of time to completely cure before proceeding to the next step.
5. There are various types of sealants. You can buy them according to your needs. Do not buy unsuitable sealants. Ask questions before buying.
The curing conditions are also very important. If you don’t know, you should ask the technical service staff of the purchasing manufacturer. Do not guess the curing time or change the curing method yourself, otherwise the sealant will directly fail to cure.
