What are the precautions for using silicone encapsulant? What are the common problems?

Unlike other adhesives, there are some differences in the performance and use of silicone encapsulants. Users need to understand more, and some details and common problems should not be ignored during the use process, so that it can play a greater use value.

What should I pay attention to when using?

After mixing the AB agent, it starts to solidify slowly, the viscosity continues to increase, and some heat is released. The more the amount of glue mixed, the faster the curing speed and the more heat released. In order to avoid the increase in viscosity, it is recommended to use up within the operating time.

After the operable time is exceeded, it does not mean that the adhesive cannot be used completely. Analyze it according to the specific situation, so as not to cause waste.

For operators who are prone to skin allergies, they need to wear protective gloves and goggles. Once it gets on the skin, it can be wiped with alcohol and rinsed with water.

Before you want to use it in large quantities, you need to try it out in a small amount. After mastering the ratio and operating skills, it can be used in large quantities.

What are the common problems?

Adhesive is not easy to cure

It may be that the amount of curing agent is small, or the storage time of agent A is too long and it is not evenly stirred.

The adhesive layer is too soft after curing

It may be that the ratio is incorrect, especially if the curing agent is too much or less, it will affect the quality of the adhesive layer. Or if you have not bought a good quality product, you can cooperate with a strong supplier and feel more assured. Not only can you focus on the research of silicone potting, but also provide customized silicone potting application solutions, which are widely used and can be applied. Used in new energy, military, medical, aviation, shipbuilding, electronics, automobiles, instruments, power supplies, high-speed rail and other industries.

There are bubbles on the surface after curing

It may be that the curing speed is too fast or the temperature is too high, causing the bubbles to have no time to automatically eliminate.

Some users have also found that the silicone potting glue is oily after curing. This is because the pouring environment is too humid or the storage time of A is too long, it is necessary to stir the A agent evenly, and continue pouring in a suitable environment. After the pouring is successful, it can be moisture-proof and high-temperature resistant.
