what are the most commonly used potting glue?

2022-05-10
Nowadays, most of the electronic products are chosen from silicone potting glue, polyurethane potting glue and epoxy potting glue. Because these three types of glue can be made for different products and choices. The adhesive properties are very good, and the sealing and waterproofing aspects are also very good. Here is a detailed explanation of the differences between these three types of potting adhesives

  • Silicone potting adhesives
The long-term protection of sensitive circuits and electronic elements is undoubtedly an increasingly important role in today's sophisticated and demanding electronic applications, and two-component silicone potting compounds are undoubtedly one of the best options. With their stable dielectric insulation, silicone potting compounds are an effective safeguard against environmental contamination and provide stress relief from shocks and vibrations over a wide range of temperatures and humidity.

  • Polyurethane potting compounds
Polyurethane elastomeric potting compounds overcome the disadvantages of brittle epoxy resins and low strength and poor adhesion of silicone resins, and have excellent water resistance, heat resistance, cold resistance, UV resistance, acid and alkali resistance, high and low temperature impact resistance, moisture resistance, environmental protection and high cost performance.

  • Epoxy resin potting adhesive
Epoxy potting adhesive has good fluidity, easy to penetrate into the product gap; can be cured at room temperature or medium temperature, curing speed is moderate; no bubbles after curing, the surface is flat, glossy, high hardness; cured products have good acid and alkali resistance, moisture, water, oil and dust resistance, moisture and heat and atmospheric aging; has good insulation, pressure resistance, adhesive strength and other electrical and physical characteristics.
