performance of powder coating

Powder coating of paint protection is better than the liquid, now the bicycle, phone sheet 

metal parts, engine shell, automobile aluminum alloy aluminum ring, all powder coating, 

above products, almost all day sun and rain, foreign body collision, so makers typically 

prefer powder coating. Powder of another benefit is environmental protection, because 

without the use of solvent, then is the economy, powder coating, powder coating / baking 

powder) without wasting, paint spraying powder material without loss. During the years 

before the said paint is to reconcile after spraying solvent paint, to paint objects after 

baking, sinter hardening. But because the paint is easy to cause the atmospheric pollution, 

high risk, but also affect the health of employees. We ordered solvent resin coating 

modified for powder electrostatic spray gun for coating with static charge attached to the 

surface of the object, after the completion of 200 DEG C baking.

Ordinary paint in about 20 - 50% of the water, and powder coatings, this part of the water to the scene to use when adding, that is, this part of the water does not need transportation, and do not need storage. In addition, the water content of the paint, when transport and storage 

temperature is less than 0 degrees, often freeze bad, and latex paint does not exist this 

problem. No preservative, traditional liquid paint, both water and food, bacteria, easy to 

bacterial contamination. Therefore, in order to prevent deterioration, to add preservatives, and latex paint without the problem of bacterial contamination, without preservatives. Than the average traditional paint odor residue, the paint will soon be able 

to disperse, it can be said that the coating that is.

Thermosetting powder coating is refers to thermosetting resin as film-forming substance, adding curing agent for crosslinking reaction after heating to form an insoluble and infusible hard texture coating. High temperature and then the coating will not like thermoplastic coating that softening, and can only be decomposed. Due to the polymerization degree is low, the prepolymer resin used in thermosetting coatings, low molecular weight, so coating leveling has good good 

decoration and low molecular weight prepolymer cured, the formation of cross-linked macromolecules. Therefore, the coating has good corrosion resistance and mechanical properties.
