& nbsp; & nbsp; There are several types of sealant, such as silicone, epoxy resin, and polyurethane. They all have a common function of encapsulating electrical equipment such as electronic components, circuit boards, transformers, etc., providing ideal performance and protecting application areas.

  & nbsp; & nbsp; Sealing adhesive has a wide range of applications, but how to choose sealing adhesive can simply be determined by whether the product has passed the ROHS EU testing standard and UL certification of SGS company. Judging from its operation, general thermal conductive sealant can be cured at room temperature or by heating, with a faster curing speed and a curing time that can be controlled according to temperature.

  & nbsp; & nbsp; In addition, looking at the performance of the potting adhesive, a good thermal conductivity system after curing can promote the timely dissipation of heat inside the power supply, improve the reliability and service life of the driving power supply product. Good flame retardant performance, strong adhesion and resistance to false positives. Long term outdoor exposure to high and low temperatures, as well as changes in the internal temperature of the power supply, will not cause the fully encapsulated material to delaminate, crack, or age. Generally speaking, by first examining the qualifications behind the sealing adhesive and evaluating its performance in various aspects, one can roughly distinguish whether it is good or bad.
