Differences Between Powder Coatings Vs Solvent Coatings
Powder Coatings PK Solvent Coatings
Powder coating does not contain organic solvents, this avoids environmental pollution caused by organic solvent coatings, fire hazards and organic solvents waste and harm to human health; powder coatings do not contain water,water pollution problem can be avoided.
The biggest feature is that the over sprayed powders can be recycled with high effective utilization.With a high recovery efficiency of the recovery equipment, the utilization of powder coating is up to 99%.
Powder coatings give high application efficiency, large thickness can be achieved more appropriate and easily than solvent-based coating or waterborne coatings do.
Powder coating application can not be effected from the climate temperature and the season, no need very skilled coating technology, easy to master and implement automated assembly coating line.
Production and application of powder coatings require special equipment,the equipment for solvent-based and water-based paint can not be directly used.
Color switching in production or application is much more fussy and complex than solvent-based and water-based paint.
Not available in thin coating for powder coating, only suitable for thick coating.
Baking temperature for powder coating is higher, usually more than 180 C, in addition to UV-curable powder coatings, most powders can not apply to heat sensitive substrate,such as plastic, wood and paper.
Powder coatings are considered as high production efficiency (efficiency), excellent film properties (excellency), eco-environmental protection (ecology) and economical (economy) of 4E-based paint products,it is growing fastest in a variety of paint species.
