Silicone sealants are 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 bonding role, but also be waterproof, moisture-proof, anti-evacuation, and adapt to hot and cold changes.
How can the expected bonding effect be achieved?
1. The bonding performance of silicone sealants after curing is the basic performance. The bonding strength varies slightly according to the brand and specifications, and branded products have more quality assurance, such as TENSAN, which focuses on the research of sealants and provides customized sealant application solutions. It has a wide range of uses and can be applied to new energy, military, 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 debonding may even occur during the use stage.
To achieve the expected 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%. The temperature should be kept at a constant temperature of 25 degrees. The glue can fully absorb the moisture in the air and effectively guarantee the bonding effect after curing.
2. Check whether the surface of the construction substrate is clean. If there are impurities such as oil, dust, etc. on the surface of the substrate, they need to be cleaned up, otherwise the bonding effect will be directly affected.
3. Control the thickness of the glue. Adjust the thickness of the glue according to the construction substrate. You can refer to the instructions or consult professionals. Too thin or too thick will affect the bonding effect. If the glue is applied too thickly, it will not only waste but also affect the curing speed. If the glue is applied too thinly, it will affect the bonding strength and quality.
The above is the relevant content about how silicone sealant can achieve the expected bonding effect. If the substrate is reworked, the residual colloid must be cleaned up before re-construction. Otherwise, the bonding is not strong and the waterproof performance is poor. It is a common problem.
