powder coating has good and bad

Powder coating is a kind of coating which exists in the state of fine powder, which has two 

different forms. It does not use any solvent, so it is called a powder coating. The coating 

has many advantages, high coating efficiency, effectively save resources, will not cause 

harm to the environment, mainly divided into two types of thermosetting coating and 

thermoplastic coating. The combination of low polymer resin and thermosetting coating, has 

a very low molecular weight, and the leveling is very good, good decoration, corrosion 

resistance and good mechanical properties, so the thermoplastic thermosetting coating with 

rapid development.

Electrostatic powder coating has the following advantages. First, the 

decoration is very convenient, and very easy to dry down, unlike some of the paint on the 

wall after it is not easy to dry, but also with a peculiar smell. Electrostatic coating on 

the smear, it is absolutely not and will not be volatile odor, so it will not harm the 

human body, causing the disease. Second, electrostatic powder can be recycled, will not 

waste materials, greatly saving the resources and improve the degree of pollution of the 

environment, completely conform to the tide of green environmental protection.

Powder coating has high mechanical strength, no pollution, save energy and resources, but it also has some disadvantages, such as curing condition to drink high, and easy to be uneven. 

Coupled with the classification of paint standards, the quality of coating is produced on 

the market is uneven, with production equipment and varieties of the coating than abroad 

have difference on a big cut, the need for further technological innovation, the enterprise 

market competition order and material facilities also need to be further improved.
