Description / Abstract:
Dow No 17 coatings range from thin clear to light gray-green, to thick dark green coatings, depending on the intended use. The clear coatings are used as a base for subsequent clear lacquers or paints to produce a final appearance similar to clear anodizing on aluminum. The light gray-green coatings are used in most applications which are to be painted. The thick, dark green coating offers the best combination of abrasion resistance, protective value and paint base characteristics.
The HAE anodic finish is probably the hardest coating currently available for magnesium. These coatings exhibit stability at high temperatures and good dielectric strength. This coating provides an excellent paint base. The coating requires a resin seal or paint for maximum corrosion protection.
