Abstract
Conventional cationic electrodeposition coatings use a combination of bisphenol type-A epoxy resin containing an amino group partially neutralized with an acid for hydration and a blocked isocyanate curing agent.
Despite its excellent performance, it has inherent limitations during electrodeposition.
In overcoming these limitations, electric energy normally used for deposition was also used to control two other chemical reactions; the crosslinking reaction, by utilizing the isomerization reaction of the propargyl group into the allenyl group, and the electrolytic reduction of sulfonium salt, which controls the electrical resistance of the deposited film.
As a result, the environmental property, the throwing power and many other properties were dramatically improved, suggesting the possibility that these limitations could be overcome.
The improvement of reactive efficiency and the improvement of the environment were able to be achieved because of the application of “Main resin fastened up the catalyst” in addition to these technologies.
This article reports on the novel environment friendly Electrolyzed Activate Deposition material (Brand name : INSULEED®) with high electric insulation coatings, its curing behavior, and film properties.
