powder coating environmental protection

Energy saving and environmental protection is the main theme of the development of the 

world, due to environmental protection and other outstanding performance, the powder 

coating will gradually replace the solvent paint. In recent years, low temperature curing 

coating began to emerge in the market. It is estimated that the coating 120 degrees C 

curing and 180-200 degrees Celsius, when compared to 40%, can save about of the electric energy, energy saving advantages are obvious. Low temperature curing coating will be the 

future development of the inevitable trend, but also the current research focus on the 

object.

The powder coating can only be heated and melted, and can be heated, cooled or extracted to form a film. Most of the raw materials used are common polymers in the market, most of the conditions can meet the requirements of the use of performance. But there are some disadvantages, such as high melting temperature, low color level, and poor adhesion to metal surface. Nevertheless, the commonly used thermal plastic paint still exhibit some unique properties, including polyolefin coating has excellent resistance to solvent; poly (vinylidene fluoride coating with outstanding weathering resistance; polyamide has excellent wear resistance; polyvinyl chloride with better price / performance ratio; thermoplastic polyester paint has the appearance beautiful, artistic advantages.

Powder coating without the use of volatile organic solvents and water solvent, so paint is a kind of inorganic solvent based paint, greatly reducing the potential safety problems caused by 

the solvent, such as because of containing organic solvent caused by operating personnel 

organic solvent poisoning or as organic solvent caused by fire disaster. From the last 

century five, 60s powder coating available so far, there has not been a major security 

incidents caused by paint. Coating is one hundred percent of solid powder coating, 

completely automatic spraying. Excessive or spray paint, through the recovery system and 

achieve the purpose of recycling, so paint almost up to 100% utilization rate, making the 

coating industry to reduce the waste processing. At the same time, the degree of pollution 

of the environment reduced to a minimum.
