I'm not quite sure what you mean by a 'dry' phosphate coating, Julie. Do you mean a "dry in place" phosphate coating that doesn't require rinsing? David McCormick discusses this technology in letter 10893.

Dear Gentleman,

You can apply organic phosphate coating, which is completely free from water rinse. this is single stage process.

Q. I have come across a requirement of DRY PHOSPHATE coating on steel surface.

I an told that the steel component is to be dipped in sodium phosphate solution for a period, depending on the phosphate thickness desired, generally 10 to 15 microns.

If it is to be dipped in solution, why is it termed Dry Phosphating?

Kindly respond, what is Dry Phosphate coating?

How to you do it?

A. It is probable that the term dry refers to the post plating condition not the phosphate process. Phosphate coatings are often oiled to improve corrosion resistance and to reduce friction.
