Food Grade Coatings

Does Teflon strike a bell?

HDPE is one it is what a lot of cutting boards are made of.

Hello Skeptical Guy, yes we sell food grade coatings for steel. Please take a look at the web site www.spc-net.com and look up SP 7888. This is a coating that goes into grain, wheat elevators, water tanks, and other food holding tanks. You can email me at norm@spc-net.com or call 778-231-6027 and I can send you more information and samples for you to try.

good luck.

If you're into designing a new fabrication, rather than doing a retrofit, use 316L and be done with it. Usually, when you design in carbon steel and go thru some scheme to apply a food grade surface treatment, you wind up spending the same or more time and money than simply using stainless in the first place. That being said, you can check with some of the major paint and coating manufacturers on their FDA approved epoxy coatings. I have used several on some very large liquid packaging machines in the past. (DuPont, Sherwin-Williams, Sickens, Buten, PPG, etc.)

"use 316L and be done with it"

Depends on product. Using teflon helps in the release of certain products.

I do not know how true it is, or its just an excepted practice. The teflon wears off, and your left with what I consider an unsanitary condition. Inspectors tend to look the other way, until pointed out, or becomes an issue.

Phoenix, you're right! Whether it's a teflon, silicone or some other polymer compound coming into contact with a foodstuff, it would probably serve as a better release medium than 316L without such a coating or lining. The original question makes no mention of what problem, if any, needs to be addressed other than not using stainless. Hence my answer to simply use 316L and be done with it. Unfortunately, many posters asking questions do not provide enough information for truly helpful, one shot answers/suggestions and I know it can be frustrating trying to guess what the problem really is.

Good day FKIA,

your original comments I took as though you knew, I only posted a reply to keep continuity to your post for the benefit of original question from skeptical guy.

"The original question makes no mention of what problem, if any, needs to be addressed other than not using stainless."

And thats true, but since skeptical came up front about his knowledge, he did not know what was actually needed.

And your comment of doing it all in 316L or 304 for that matter was a good reply, that is something that is talked about often to relief headaches. delays, quality factors..... you seem familiar with the rest.

Skeptical, if you are in the U.S., there are various coatings and adhesives approved for food use. The Food and Drug Administration (FDA) is charged with issuing the regulations, and they are published in the Code of Federal Regulations (CFR). The complete list of regulations for food-approved materials is here. The particular section of interest to you is 21 CFR 175, "INDIRECT FOOD ADDITIVES: ADHESIVES AND COMPONENTS OF COATINGS." There are many coatings such as epoxies that have been approved. If someone claims to have an FDA approved coating or adhesive, it should be listed in 21 CFR 175. Otherwise buyer beware. GLTY.
