Advantages, disadvantages, and differences of various potting adhesives

The advantages, disadvantages, and differences of various potting adhesives include the following types:

1. Silicone potting adhesive: Silicone potting adhesive has excellent high-temperature resistance and can be used in high-temperature environments. It also has excellent weather aging resistance and electrical insulation performance, suitable for outdoor environments. However, the chemical corrosion resistance of silicone sealant is relatively poor and is not suitable for some environments with strong chemical corrosion.

2. Polyurethane potting adhesive: Polyurethane potting adhesive has excellent adhesion and chemical corrosion resistance, and is suitable for various environments. It can also be used over a wide temperature range and has high heat resistance. However, the aging performance of polyurethane potting adhesive is relatively poor and is easily affected by ultraviolet radiation and oxidation.

3. Acrylic sealing adhesive: Acrylic sealing adhesive has good weather resistance and aging resistance, and is suitable for outdoor environments. It also has high adhesion and chemical corrosion resistance. However, acrylic potting adhesive has poor high-temperature resistance and is not suitable for high-temperature environments.

4. Polyurethane silicone composite potting adhesive: Polyurethane silicone composite potting adhesive combines the advantages of polyurethane potting adhesive and silicone potting adhesive. It has good high-temperature resistance, weather resistance, and chemical corrosion resistance. However, its cost is relatively high.

Overall, there are differences in performance between different types of potting adhesives, and the selection of a suitable potting adhesive should be determined based on the specific usage environment and requirements.
