In the application process of silicone potting compounds, degassing is a crucial step in ensuring product quality. Its core purpose is to ensure that the cured compound is free of air bubbles and pores, both internally and on the surface, thus avoiding impacts on the subsequent performance of the product. Many users believe that degassing simply requires opening a vacuum chamber for extraction; however, improper operation of this step can lead to a series of problems. This article will detail the consequences of degassing abnormalities, the key factors affecting degassing effectiveness, and preventative measures.
The performance of electronic encapsulation AB glue hinges on correct pouring operations and scientific curing techniques. Improper operation not only wastes materials but also severely impacts its core protective properties such as insulation, waterproofing, and shockproofing. Therefore, operators must master relevant practical skills to ensure the adhesive functions effectively.
Silicone potting compounds are important protective materials for electronic devices, effectively providing waterproofing, moisture resistance, dustproofing, insulation, thermal conductivity, and corrosion protection, ensuring the stability and lifespan of electronic devices. Their curing methods are mainly divided into room temperature curing and heated curing. In practical applications, if abnormal curing occurs (such as incomplete curing, slow curing speed, or no curing at all), it is mainly caused by the following three core factors:
Many customers have heard of silicone potting and sealants, but often confuse the two, even mistakenly believing they are the same product. In fact, they are different products. While the core differences may not be immediately obvious, they differ significantly in applications and performance. Below is a detailed analysis.
When using electronic sealants, deterioration may occur, manifesting as loss of basic adhesion, becoming too soft or too hard, making filling impossible, and ultimately losing its original sealing and protective properties. To avoid waste due to adhesive deterioration, preventative measures and proper storage are crucial.
Silicone potting compound boasts excellent overall performance, providing outstanding electrical insulation, waterproofing, moisture resistance, and strong sealing after curing. It exhibits no significant shrinkage during curing, and the compound is soft and removable, facilitating disassembly and repair in case of electronic device malfunctions. It is a commonly used material for the encapsulation and protection of electronic devices. Many people are curious: What is the state of silicone potting compound after complete curing? Is it transparent?
