4.1 The role of DMEA as an additive

DMEA dimethylamine is mainly used as an additive in solar panel coatings, and its functions include:

  • Improve the adhesion of the coating: DMEA can react with other components in the coating to form stable chemical bonds and enhance the adhesion of the coating.
  • Improve the leveling of the coating: DMEA has surface activity, which can reduce the surface tension of the coating and make it easier to be evenly distributed on the surface of solar panels.

  • Color Change: UV rays can cause changes in chromophores in the material, causing the color to turn yellow or darken.

5.2 UV resistance mechanism of DMEA

DMEA dimethylamine improves the UV resistance of the coating through the following mechanisms:

  • Ultraviolet absorption: DMEA molecules contain groups that can absorb ultraviolet rays, which can effectively reduce the direct irradiation of ultraviolet rays on the coating.
  • Free Radical Capture: DMEA can react with free radicals generated by ultraviolet excitation, preventing further reactions of free radicals and reducing the occurrence of photooxidation reactions.
  • Stable effect: DMEA can form stable chemical bonds with other components in the coating, improve the overall stability of the coating, and reduce degradation caused by ultraviolet rays.
