Silicone sealants are one-component adhesives. Both the operation method and the curing method are relatively simple. After curing, they have outstanding performance and are favored by all walks of life. However, little is known about the performance, storage conditions and usage methods of silicone sealants. The following Spread some knowledge about this for everyone.
What is silicone sealant:
Silicone sealant is similar to a kind of ointment. After curing, the colloid is elastic and has a high elongation rate. Once the glue comes into contact with air, it will undergo a curing reaction, thus forming a film with high gloss. This kind of colloid can resist odor, has strong weather resistance, good shock resistance, and can also have good moisture-proof and waterproof effects.
The main raw material of silicone sealant is polydimethylsiloxane, and then some crosslinking agents, plasticizers, fillers, and coupling agents are added. There are no special restrictions on the use of good quality, and there is no corrosion to any substrate. At present, only the products of big brands can guarantee these performances. They can not only focus on the research of sealants, but also provide customized sealant application solutions. They are widely used and can be used in new energy, military industry, medical treatment, aviation, shipbuilding, electronics. , automobiles, instruments, power supplies, high-speed rail and other industries.
Storage conditions of silicone sealant:
Silicone sealant must be stored in a cool and ventilated place. The warehouse needs to be kept away from infants and young children, and protected from insects and rats to avoid waste caused by biting the hose. In the storage stage, it can be stored as general chemicals, away from fire sources and explosives.
Precautions for using silicone sealant:
Silicone sealants must be tested for compatibility and reliability before use, because the specifications of silicone sealants are different, and the performance after curing is different. Before purchasing, it is necessary to understand the elongation, adhesion strength, and volume of the sealant after curing. Resistivity, dielectric constant, etc.
Disposable unused silicone sealants need to be sealed to facilitate the next use. If it is not stored properly, it cannot be used further if it enters the air.
