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 |
MAJOR RESIN SYSTEM |
|
| Thermosetting Powder Coating | Thermoplastic Powder Coating |
| Epoxy | Polyvinyl Chloride |
| Epoxy Polyester / Hybrid | Polyolefins |
| Polyurethane | Nylon |
| Polyester TGIC | Polyester |
| Acrylic | Polyvinylidene Fluoride |
