Resin - serves as binder that forms paint film
Pigment - provides color
Solvents - maintain liquid state and influence application
Additives - effect flow, cure and surface appearance

Types
Polyester - typically high solids with good flexibility
Acrylic - conventional solids with good hardness
Silicone - modified polyester-medium solids with better weathering
Fluoropolymer - best weathering

Powder Finishes

Constituents 
Resin & crosslinker serve as binder that forms paint film
Pigments provide color
Additives affect fluidization & application properties

Types
Polyester, Modified polyester, Fluoropolymer

Anodize

An electrochemical process that enhances the aluminum’s natural oxide surface layer by forming an even more durable oxide film that can have a variety of colors.

Mechanical and Chemical Surface Treatments

• Buffed & burnished to a mirror like finish
  
• Abrasive blasted to a rough texture appearance
  
• Caustic Etch - uses a caustic solution to give a silver-white appearance
  
• Floride Etch - uses a fluoride solution to give a matte appearance
  

Bright Dip - polished first then chemical treated to yield a bright mirror like finish usually anodize afterwards to add a protective layer and/or add color
