The Comparison Between Metal Powder Coating And Traditional Paint

Because metal powder coating has excellent performance, its market share is steadily improving. As the requirement of increasingly stringent environmental laws on the atmosphere volatile organic compounds content, the coating industry finds ways to improve the coating technology and reduces environmental pollution. After long-term experiments and tests, they finally find the silicon powder coating technology which is able to achieve the best coating.

Metal powder coating does not use organic solvents, water and other volatile solvents. Powder coatings are an inorganic solvent-based paint which greatly reduces the security risks arising due to the solvent, such as operating personnel due to the presence of organic solvents and organic solvent poisoning or the organic solvent fire. Metal powder coating available from the fifties and sixties of the last century, so far, there is no occurrence of major accidents caused by powder coating. Metal powder coating is a one hundred percent of the solid powder coatings, can be completely automatic spray. Excess or super-spray powder coating, through the recovery system device to achieve the purpose of recycling, the metal powder paint almost up to 100% utilization rate, making the coating industry to reduce waste disposal, while the extent of environmental pollution reduce to a minimum.

Looking at the energy costs of the metal powder coating and liquid paint, the liquid coating containing volatile organic compounds results in evaporation of volatiles to the atmosphere. Metal nickel powder coating will not have such a waste which greatly reduces the energy use. Electrostatic coating machine spit out a large quantity and a spray can thick film, do not have to repeat the spraying, do not have to hit the primer in the same thickness, the use of metal powder coatings for painting quickly can save the cost of time. It does not need static painting equipment which can save device space. In addition, the powder coating baking time is less than the liquid coating, so you can greatly reduce fuel energy, shorten the line of painting operations, increase productivity, and promote the overall production efficiency.

If directly paint the powder coating on iron wood or aluminum with the appropriate pre-treatment, the coating surface can be obtained by baking performance, such as the persistence of the coating including: abrasion resistance, impact resistance, adhesion resistance, toughness, corrosion resistance and resistance to chemical performance. The powder coating for outdoor use, in addition to the above advantages, including high weather resistance and stain resistance. Especially in the thicker coating, powder coating a coating of 50-300μm and the leveling is good, not like the thick coating of solvent-free coating will have to drop vertical or stagnation phenomenon.

In order to enhance the multi-functions of metal powder coating, people can adjust the color, luster and surface flat performance according to the preference. Even for some special metal powder coatings and some special wrinkles manganese powder coatings. Powder coating electrostatic principle sprays painting equipment to achieve a fully automated, without waste of human resources. Even artificial coating having to go through the long-term training, you can spray a good film.

It is unnecessary for metal powder coating with 100% solid ingredients adding any solvent. Thus it saves packaging and reduces storage space. In the spraying process, if there are bad spraying parts, it can use air gun to blow without baking. And then spray up. Therefore, it is unlikely to have the phenomenon of surface flow and drip paint thereby reducing the probability of re-coating rework. In ingredients of film formation, solvent-based paints are about 60 to 65 percent, while the metal powder coating can be achieved almost 100%. It is not attached to the object being sprayed powder and can be recycled use. Generally speaking, using metal powder coating technology can improve production efficiency and economic efficiency.
