The Class 1A coating provides corrosion protection for aluminum and aluminum alloys when left unpainted. The coating also improves adhesion of paint finish systems.
The Class 3 coating provides corrosion protection for electrical and electronic applications where lower electrical resistance contacts are required. The Class 3 coating is thinner than the 1A coating, therefore more susceptible to corrosion.
