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
