- Surface promoters: control surface properties of powder coating’s final film. The group includes:
• Coating powders and Powder coating flow and leveling control agents
• Degassing agents
• Gloss increase agents and Matting agents
• Scratch resistance promoters
• Stain resistance Promoters
• Etc.
2-Light , weather , and Chemical resistance Promoters, selected by the needs of final coating film and coated surface:
• UV stabilizers
• corrosion inhibitors, etc.
3-Texturing agents: used to get special surface effects like
• hammertone surfaces
• wrinkle and ripple surfaces
• sandpaper surfaces
• etc.
it should be noticed that final surface texture is impressed significantly by producing process as well as the type and amount of the additives you add to the formulation.
4-Electro charge agents and coating powder flow promoters:
The group Includes two different Subgroups that are used in special situations to:
• control the amount and homogeneity of sprayed powder during application
• increase the efficiency of spraying
• control the density of electric charge and reduce it’s danger
• etc.
