Yes, Frost has been going many years, starting originally in the US I believe. Their prices cause a young Yorkshireman like myself to take a sharp intake of breath! The quantities of chemical included in their kits often look like there would appreciably more than you'd need for a 'one-off' item

The passivating solutions to go with zinc plate don't mention chromate, and I'd guess that they probably don't utilise chromate, especially for a DIY kit.

From what I could see, there are no formal Safety Data Sheets (i.e. MSDS as were) directly on offer on the website. I'd guess that they must have to supply them, but may do so quietly, as those sheets often contain info that might be of interest to competitors.
