How to achieve the best curing effect of silicone potting compound? What is the difference between different construction temperatures?


All users who need to use silicone potting adhesives are trying to achieve the best curing effect. In order to achieve the best curing effect, it is necessary to have a detailed understanding of the performance of the adhesive's working parameters and find a better way.

How to achieve the best curing effect of silicone potting adhesive?

1. If it is a one-component product, it needs to be exposed to the moisture in the air for curing. Try to put it in an environment with a temperature of 25 degrees and a relative humidity of 50% for curing, and the curing of a 3mm adhesive layer can be completed within 24 hours. If you want to show excellent physical properties, you need to wait seven days.

2. When the thickness of the adhesive layer is greater than 6 mm, it is recommended to perform two potting. If you want to speed up the curing speed, you can increase the temperature appropriately, but it should not exceed 50 degrees. Compared with raising the temperature, the effect of increasing the humidity is better.

What is the difference between different construction temperatures?

In winter, the temperature and humidity are relatively low, and the curing speed of the adhesive is slower. In summer, the temperature and humidity are relatively high, making it easier to complete curing quickly. When the temperature changes, the viscosity of the adhesive will also change, which will affect the curing speed.

Why is the silicone potting compound easy to turn yellow?

When the adhesive is irradiated by ultraviolet light for a long time, the catalyst will react chemically, resulting in yellowing. If you want to change the yellowing phenomenon, you must use a special formula and choose a high-quality adhesive. Cooperating with powerful suppliers will give you more peace of mind. Not only can you focus on silicone potting research, but you can also provide customized silicone potting application solutions. It has a wide range of uses and can be used in new energy, military, medical, aviation, Shipbuilding, electronics, automobiles, instruments, power supplies, high-speed rail and other industries.

Adhesives used outdoors are prone to yellowing, which affects the aesthetics. Fortunately, yellowing does not have much impact on performance, almost negligible. Operate according to the correct process and cure at the appropriate temperature. Resist yellowing and high and low temperature as much as possible, use it with confidence.
