A few tips on silicone sealants, in-depth knowledge for effective use


Silicone sealant is a one-component adhesive, both the operation method and the curing method are relatively simple, the performance after curing is outstanding, and it is favored by all walks of life, but little is known about the performance, storage conditions and use methods of silicone sealants. The following Spread some knowledge about this for everyone.

What is a silicone sealant:

Silicone sealant is similar to an ointment. After curing, the colloid is elastic and has a large elongation rate. Once the glue liquid comes into contact with the air, a curing reaction will occur, thereby forming a layer of high gloss film. This colloid can resist odor, has strong weather resistance, good shock resistance, and also has good moisture-proof and waterproof effects.

The main raw material of silicone sealant is polydimethylsiloxane, and then some cross-linking agents, plasticizers, fillers, and coupling agents are added to make it. There are no special restrictions on the use of good quality, and there is no corrosion to any substrate. At present, only big brand products can guarantee these properties, such as: TENSAN, which can not only focus on the research of sealant, but also provide customized sealant application solutions, which are widely used in new energy, military, medical, aviation , ships, electronics, automobiles, instruments, power supplies, high-speed rail and other industries.

Silicone sealant storage conditions:

The silicone sealant must be stored in a cool and ventilated place. The warehouse needs to be kept away from infants and young children. Do a good job of protection against insects and rodents to avoid waste caused by biting the rubber tube. In the storage stage, it can be stored in accordance with general chemicals, away from fire sources and explosives.

Precautions for the use of silicone sealant:

Silicone sealants must be tested for compatibility and reliability before use. Because the specifications of silicone sealants are different, the performance after curing is different. Before purchasing, you must understand the elongation rate, adhesion strength, and volume of the sealant after curing. Resistivity, dielectric constant, etc. One-time unused silicone sealant needs to be sealed for the convenience of next use. If stored improperly, the air will not continue to be used.

A few small knowledge about silicone sealant are the above. Users must understand when purchasing. If there is still something they don’t understand about the glue, consult the staff before purchasing.
