Determine the type of film coating polymer structure of the hole, i.e., different types of coatings have different characteristics. The following suno from Dongguan - specializing in the production of various beverages easy open lid, aluminum easy open lid and tinplate easy open lid safe side business to serve you briefly explain what types EOE paint, I hope for your help .

1, epoxy phenolic coatings applied in the entire board in more than 70%, which is characterized by dense better than other types of paint, but more sensitive to bake, bake less porous coating more serious when the crosslinking reaction is not sufficient, it will generate residual organics migration issues, then bake excessive adhesion significantly lower lung.

2, melamine coatings commonly used in tomato sauce cans, it belongs to the masking coatings, corrosion under the film by coating concealed and difficult to observe. In addition, the soft coating, the next film should avoid scratching when canning produce corrosion.

3, aluminum paste coating, the zinc oxide coating has good resistance to sulfur, but not with a pH of less than 5, the food, the filler otherwise easily dissolved in an acidic medium and reduce its corrosion resistance.

4, the organic solids content of the coating sol is high, a thick coating film can be obtained. And flexibility is good, but not as dense type epoxy phenolic coatings, commonly used in tinplate lid full face paint.

5, the epoxy coating is characterized by an amino group protection of the flavor of the food is good, good alkali resistance, corrosion resistance, but in general. So the flavor of the light-sensitive beverages such as canned milk, amino epoxy paint should be applied to the entire board, and then use a vinyl coating to make full tank gunning.
