Problems solved by technology

At this time, the heat generated by electronic equipment accumulates and increases rapidly. Under the ambient temperature, in order to ensure the normal operation of electronic components with high reliability for a long time, the ability to dissipate heat in time becomes an important limiting factor affecting their service life.
The existing method to effectively improve the heat dissipation effect of powder coatings is mainly to fill the powder coating with metal or graphite powder, which leads to the inability of the product to meet its insulation performance requirements during use. Therefore, a kind of heat dissipation performance is prepared. Better paint is necessary
