Serra Partners with Tiger Drylac to Solve Powder Coatings Problems
With the help of a powder coating consultant and partnering with a major powder manufacturer, Serra was able to increase production and decrease the dollar amount of rejected parts.
Serra found that when powder coating was applied over galvanneal (zinc-coated) material, an increasing number of blemishes were found, including fisheyes. Fisheyes are caused by outgassing: the release of gasses from the zinc-coated metal as the part is baked in the powder coating process. This outgassing caused a rejection rate well above the norm, also creating a major problem due to the customer’s request for perfect parts.
