Chromate Properties

2005

In cold rolling mills we use chromate solution I wish to know the viscosity of chromate at room temperature & pH value of chromate.

Hi, Davinder. I might be misreading the question, but if you're treating your rolls with a solution, why can't you tell us the pH and viscosity instead of asking us to guess at it? 'Chromate' is CrO3--, which is to say it would be any arbitrary concentration, but it's also slang for a range of proprietary post treatment solutions which also contain dichromates, and possibly fluorides and sulfates, accelerators, dyes, and miscellaneous ingredients, with the darker yellow chromates being thicker than the clear and blue-brights.
