Question 1

How quickly does FRI-10 prevent flash rust on untreated steel?

Accepted Answer

FRI-10 prevents flash rust formation on Sa 2.5 blasted or mechanically cleaned steel for a minimum of 30 minutes after waterborne primer application at ambient conditions (20°C, 60% RH). Performance may vary under high humidity or salt-contaminated surfaces, where dosage should be increased toward 2.0%.

Question 2

Is FRI-10 compatible with acrylic, alkyd-acrylic, and epoxy waterborne binder systems?

Accepted Answer

Yes. FRI-10 is compatible with acrylic dispersion, alkyd-acrylic hybrid, and waterborne epoxy binders. It is best added to the aqueous phase during pigment dispersion or early let-down to ensure uniform distribution before the film-forming stage.

Question 3

Does FRI-10 affect intercoat adhesion or final film properties?

Accepted Answer

At recommended dosage (0.5–2.0%), FRI-10 does not measurably affect intercoat adhesion, gloss development, or water resistance. Overdosing above 3.0% may increase water sensitivity of the dried film and is not recommended.
