How do you measure wet film thickness on shop-applied organic zinc-rich primers to accurately predict dry film thickness?

Our shop applies a great deal of OZ primer, and we have found that WFT readings with a standard gauge are not accurate predictors of DFT.

What are the significant differences in performance between an inorganic zinc primer (ethyl silicate) and an organic zinc primer (epoxy), given the same application and exposure conditions?

If I apply a zinc-rich epoxy primer at 3 mils’ dry film thickness in the shop with air temperature of 90 F, what checks can I make to determine when it is safe to handle and stack the primed steel components?

Daily Quiz (12)

True or false: If a zinc-rich primer has a silicate binder, it is classified as an inorganic rather than an organic zinc-rich.

True or false: Organic zinc-rich coatings are sometimes recommended for the repair of damaged areas on galvanizing and inorganic zinc-rich-coated steel.

True or false: Organic zinc-rich coatings are generally more tolerant of deficient surface preparation than inorganic zinc-rich coatings.

When spraying zinc rich coatings, why is it useful to have the spray pot or container positioned at or above the level of the work?

What special mixing equipment may be required for zinc-rich paints?

What special mixing equipment is required for zinc-rich paints?
