FORMULATION OF POWDER COATING
|
Main raw material components used in powder coating |
Resin |
Resins are the key component,the range is increasing steadily to attempt to meet the new needs in market. |
Accelerators |
They are used to accelerate the curing reaction rate |
Curing agent |
Used according to the type of resin system and final properties required of coating |
Pigments |
General solid particulate materials such as titanium dioxide or carbon black |
Extenders |
Used to provide opacity and act as a filler,such as aluminum silicate |
Fillers |
Used to reduce the cost of coating formulation and improve certain properties such as flow,surface,etc. |
Degassing Agent |
Used to eliminate gas bubbles that may cause film porosity or poor finish |
Dry flow Agents |
Improve the free flow of powders in the production delivery system |
Flow agents |
Improve the flow of the molten coating to enhance film properties and minimize surface defects. |
Matting agents |
Used to reduce the gloss of the cured film. |
Texturing Agent |
Used to control or enhance the gloss level and surface effect of cured film |
Waxes |
Provide slip ,hardness,scratch resistance,and act as free flow powder and anti-bridging agent in processing |
