How does silicone sealant achieve the desired bonding effect? What measures can be taken?


Silicone sealant is mainly composed of polydimethylsiloxane and cross-linking agents, fillers, plasticizers and coupling agents. Such adhesives are very popular in the industrial manufacturing industry and have many uses. After use, they can not only play a good role The bonding effect can also be waterproof, moisture-proof, anti-outgassing, adaptable to changes in cold and heat, etc.

How can we achieve the expected bonding effect?

1. The bonding performance of silicone sealant after curing is the basic performance. The bonding strength varies slightly depending on the brand and specifications. Brand products have better quality assurance, such as TENSAN, which focuses on the research of sealants and provides customized sealants. Application solutions have a wide range of uses and can be used in new energy, military industry, medical, aviation, shipbuilding, electronics, automobiles, instruments, power supplies, high-speed rail and other industries.

2. Master the correct operation process. The operation process is related to the overall performance of the glue after curing. If the construction is wrong, poor bonding strength is normal, and degumming may even occur during use.

To achieve the desired bonding effect, the following measures can be taken:

1. Understand the temperature and humidity of the construction environment. The humidity should be controlled between 40% and 70%, and the construction should be kept at a constant temperature of 25 degrees. The glue can fully absorb the moisture in the air and effectively ensure the bonding effect after curing.

2. Check whether the surface of the construction base material is clean. If there are oil, dust and other impurities on the surface of the base material, they need to be removed, otherwise the bonding effect will be directly affected.

3. Control the glue thickness and adjust the glue thickness according to the construction base material. You can consult the instructions or consult a professional. Too thin or too thick will affect the bonding effect. If the glue is applied too thickly, it will not only waste money but also affect the curing speed. If the glue is applied too thin, it will affect the bonding strength and quality.

The above is the relevant content on how to achieve the expected bonding effect of silicone sealant. If the base material is reworked, the residual colloid must be removed before re-construction. Otherwise, weak bonding and poor waterproof performance are common problems.
