对于有用原材料操作中不可忽视的细节，我们必须首先引起每一位员工的注意，以便越来越有效地提高此类原材料的可用性。今天我们来看一看。

As for the details that can not be ignored in the operation of useful raw materials, we must first attract the attention of every staff, so as to more and more effectively improve the availability of such raw materials. Let's take a look here today.

Different topcoats differ in hardness, flexibility, adhesion and durability. Polyester is the most widely used coating at present, with general durability, good hardness tolerance and moderate quotation. Silicon modified polyester has high durability, gloss and color durability, but its resistance is slightly reduced. High weather resistant polyester has high cost performance. PVDF has excellent durability and good tolerance, but it has low hardness, few available colors and high price. The finish of color coated plate is mainly affected by the use, application environment, corrosivity, service life, durability, processing method and deformation degree.
Different primers have certain differences in adhesion, wear resistance and corrosion resistance. Epoxy resin has excellent adhesion to the substrate and high corrosion resistance, but its resistance is not as good as other primers. Polyester has good adhesion to the substrate and excellent corrosion resistance, but the corrosion resistance is not as good as epoxy resin. Polyurethane is a kind of primer with good comprehensive properties. The primer is generally selected by the supplier according to the production process, application, corrosivity of application environment and matching with the finish paint.
Corrosion resistance usually increases with the increase of coating thickness. When ordering, the coating thickness shall be determined according to the corrosion of the service environment, service life, durability and other factors.
