Powder Coating

· Corrosion resistance depends on type of material used and pre-treatment process

· Surface must be pre-treated before powder coat or part will be at risk of corrosion and adhesion issues

· Chips or incomplete coverage adds to risk of corrosion

· Can range from 70 to 150μm

· Thicker than traditional liquid paint

· Improves appearance

· Various colors and textures available

· Heat cured finish

· Material composition and pre-treatment may have enhanced abrasion resistance

· Creates a hard finish that resists abrasion well

E-Coating

· Good corrosion resistance

· Provides physical and chemical barrier to corrosion

· Typically 12 to 30μm but can be more

· Often used to increase surface thickness

· Thickness of application is uniform

· Good durability

· Heat cured finish

· Good longevity

Zinc Plating

· Provides physical barrier to corrosion

· Acts as a sacrificial anode to prevent corrosion

· Parts can sustain minor damage and remain corrosion resistant

· Can range from 5 to 25μm

· If use as an undercoat for other finishes, poor adhesion

· Best for detailed surfaces and not heavy-duty applications

· Very strong finish

· Highly durable to abrasion

Geomet

· Provides barrier resistance to corrosion

· Creates passivation effect on surface

· Between 5 to 7.6μm

· Can be used under a painted finish

· Mid abrasion resistance

· Electrically conductive finish

· Good resistance to chemicals, organics, heat, salt

Anodizing

· Good corrosion resistance

· Commonly used for saltwater or marine environments

· Ranges from 0.5 to 150μm

· Hard, wear resistant finish

· Often used for parts that come in frequent contact with other material

Passivation

· Good corrosion resistance through an inert, oxide layer

· The process removes free iron from the surface leaving a thin and transparent oxide film

· Does not change durability or abrasion resistance

Galvanized Dipped

· Provides barrier resistance to corrosion

· Acts as a sacrificial anode to prevent corrosion

· At more than 254μm the finish is prone to flaking

· Poor appearance

· Can adjust thickness of finish to accommodate needs

· Often used in harsh environments because of durability

· Good abrasion resistance

· Good durability and longevity

· Surface damage can result in corrosion
