What are the requirements for the curing environment of silicone sealants?


Silicone sealant is in a paste state and is installed in a sealed tube, so it will not be unable to be squeezed out. The main function of silicone sealant is bonding and fixing. After curing, it can provide weather resistance, earthquake resistance and good moisture-proof performance. Good quality can also achieve temperature resistance and can perform normally in a zero-degree environment.

How does silicone sealant cure?

Silicone sealant is a one-component sealant, and its curing method is completely different from that of two-component sealant. This adhesive will undergo a curing reaction as long as it comes into contact with air. During construction, as long as the glue is squeezed to the interface to be applied, the curing reaction will occur on its own.

Does silicone sealant have any requirements on the curing environment?

1. Silicone sealant can be cured at room temperature. During the curing process, the vulcanization reaction depends on the air humidity. Therefore, there are certain requirements for the humidity of the curing environment. It cannot be too dry, otherwise the curing time will be prolonged.

2. Silicone sealant can be constructed in an environment of 5 to 35 degrees. If the temperature of the construction environment is too high or too low, it is not conducive to construction. If the temperature is too low, frost will appear on the surface of the substrate, and the glue will not be able to bond with it. Conducive to curing. If the temperature is too high, the curing speed will be too fast, which is not conducive to the release of ethanol in the glue.

3. Silicone sealants should be constructed and cured in a room temperature environment as much as possible, so that the properties of the glue can become stable after curing. If the silicone sealant is constructed and cured at low or high temperatures, the properties of the colloid will change slightly.

During the construction stage, as long as you properly grasp the operating methods and construction environment, and choose good quality glue, you can achieve the expected curing effect. For example, TENSAN focuses on the research of sealants and provides customized sealant application solutions. It has a wide range of uses and can be used in New energy, military industry, medical, aviation, shipbuilding, electronics, automobiles, instruments, power supply, high-speed rail and other industries.

Silicone sealant not only has requirements for the curing environment, but also has certain requirements for the field of use after construction. Although the glue has good moisture-proof and waterproof properties after curing, it cannot invade water for a long time and cannot be used as a waterproof material.
