Is there a difference in curing speed for different types of sealant? How to achieve the best adhesive effect?

2023-01-30

There are many differences between one-component and two-component sealants from glue mixing to curing. Which kind of adhesive you want to use, you need to know about it in advance. See how to operate to achieve the ideal bonding effect, can play a better performance.

 

Is there any difference in the curing speed of different types?

When the one-component product is cured, it needs to contact the moisture in the air, and slowly cure from the surface to the inside. The deeper the glue joint, the longer the curing time. Unable to freely control the curing speed, which is slower than that of two-component products. When the two-component adhesive is cured, the curing speed can be adjusted by increasing or decreasing the content of the curing agent. The curing speed can also be accelerated by heating, which is easier to operate.

 

How to achieve the ideal bonding effect?

For various adhesives, adhesion is the most basic performance. Loss of adhesion, will not be able to play other performance. In order to achieve the best bonding effect, the temperature and humidity should be well controlled. Normally, the temperature should be between 20 and 30 degrees, and the relative humidity should be between 40% and 70%. If the adhesive layer is only 3 mm, it can be cured within 24 hours.

 

High-quality sealant will not release by-products during curing, and the pollution to the environment is almost zero, so it can be used with confidence. Cooperating with powerful suppliers will give you more peace of mind. You can not only focus on sealant research, but also provide customized sealant application solutions, which 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.

 

In order to achieve a better bonding effect, it is recommended that the thickness of the adhesive layer should not be too thick or too thin. Some users believe that the thinner the bond line, the easier it is to cure. In fact, if the glue layer is too thin, it will reduce the quality after curing. It is recommended that the minimum thickness should not be less than 1 mm, otherwise the quality of the adhesive layer will be affected.

 

Use some tricks to improve the adhesiveness of the adhesive, and it will be tightly bonded with the bonding object. In this way, after normal curing, it can exert full performance without any worries.
