High-Performance Potting Compound Chemistries for Electronics Protection

LED drive power potting adhesive is suitable for potting protection of general electronic components, power modules and circuit boards, as well as potting of various electronic appliances, such as switching power supplies, drive power supplies, automotive HID lamp module power supplies china, automotive ignition system module power supplies , Appliance controller, network transformer, etc. Many customers do not understand the use of LED sign parts. Now I will explain the use of LED driving power potting glue.

1. Before mixing

A and B components should be fully stirred manually or mechanically to avoid performance of LED parts changes caused by the sedimentation of filler.

2. Mixing

Weigh the two components according to the ratio of 1: 1 and mix them in a clean container, and the error cannot exceed 3%, otherwise the performance after curing will be affected.

3. Defoaming

Natural defoaming: let the mixed glue stand for 20-30 minutes, vacuum defoaming: vacuum degree is 0.08-0.1MPa, vacuum for 5-10 minutes.

4. Filling

The rubber should be filled within the operating time, otherwise it will affect the leveling. The substrate surface is kept clean and dry before potting in LED control Card.

5. Curing

Room temperature or heat curing can be. The curing speed of the glue LED parts supplier has a great relationship with the curing temperature. It takes a long time to cure in winter. It is recommended to use a heating method to cure at 80 ° C for 15-30 minutes. It usually takes about 6-8 hours to cure at room temperature.
