Phosphate Free Pretreatment Chemicals

A. Hi Eric. All of the major suppliers to the pretreatment industry have phosphate-free technologies and nano technologies, and there are many others besides the ones you list. Unfortunately "nano" has become a buzzword which often no longer means what it once implied (the emergence of unforeseen special properties which don't present themselves in mass processing). There are also companies which do competitive market analysis and can answer questions about the market penetration in different sectors by various companies.

Comparing the offerings of one company to another unfortunately doesn't suit this forum well because many posters are unknown to any of us, and when there is commercial gain available, we sometimes see postings from "satisfied users", with the IP address revealing that they were actually posted by the company which was recommended. Also, this site can only exist courtesy of supporting advertisers and it is impossible to find any who will support discussions which steer potential customers towards their competitors.

Please demand studies proving 10-15 year usefulness in a salt-air environment! The world is unsustainably drowning under corroding metal garbage which was improperly finished, and the last thing the earth needs is to continue on this path of manufacturing a ton of metal which will quickly corrode, in the name of saving an ounce of phosphate. Good luck.
