New energy electrical insulation powder coatings need to do these points

At this stage, in the new energy automotive industry, the required powder coatings have high requirements, especially in terms of insulation and voltage resistance
.

In order to meet the increasing requirements, every link of production and use should be strictly controlled:

The purchase of raw materials should be strictly screened and verified to ensure that the quality of raw materials meets the production needs;

The formulation process should be through multiple experiments to meet customer needs and related standards;

The production process is precisely controlled to prevent impurities from being mixed into it;

In addition, pay attention to the matching preparation
of insulation refinish paint.

In order to ensure that the performance of the coating is excellent in all aspects, the following aspects need to be done:

(1) Use the epoxy resin produced by the two-step method, and according to the actual situation, match the resin of different epoxy equivalents, and ensure that the cross-linking density of the coating is high enough with the help of imidazole catalyst, which is conducive to the production of excellent coating online coatingol.

with tight texture and complete uniformity.

(2) Strictly control the selection of materials, such as when selecting fillers, to ensure that its dielectric constant is low and resistivity is high, so as to ensure that the coating has excellent electrical insulation and heat resistance
.

(3) In the production process, special production facilities are used to prevent other impurities from being mixed in and reduce the influence of
impurities and metal particles on electrical insulation properties.
