Potting Adhesive

In the design of switching power supplies, the application of potting adhesive plays a crucial role. Below are some requirements and considerations to keep in mind when selecting and applying potting adhesive for switching power supplies:

1. Hardness Requirements: Considering the components involved in switching power supplies, such as oscillators, transformers, and inductors, the hardness of the potting adhesive should be moderate. If the potting adhesive is too hard, it may affect the oscillation frequency of the components, thus impacting the output voltage and stability of the power supply. Generally, potting adhesive with a hardness in the range of 40-60 Shore A is more suitable.

2. Temperature Performance Requirements: Switching power supplies generate a considerable amount of heat, so it is crucial to select potting adhesive with high temperature resistance. The potting adhesive should be able to withstand alternating changes from very low to high temperatures to ensure the power supply operates normally under various environmental conditions.

3. Compression Elasticity and Bond Strength: The potting adhesive should possess proper compression elasticity and bond strength to prevent components from loosening or detaching under external forces such as vibration and impact. This helps maintain the stability and reliability of the power supply.

4. Waterproof and Flame Retardant Properties: Switching power supplies often need to operate in harsh environments, so the potting adhesive should have certain waterproof and flame retardant properties to protect components from hazards like water, dust, and fire.

5. Environmental Friendliness: Selecting potting adhesive that complies with environmental standards is crucial. Ensure that the potting adhesive does not pollute the environment and aligns with relevant environmental regulations and standards.
