: I am Sumitha Sumanaweera of Sri Lanka. Interested to try rubber coating steel
: pipe. Do you have any information or access to such on toxicity of rubber
: coatings in potable water

You would probably want to contact the manufacturers directly. They should have information on toxicity.

One elastomeric roofing compound used is Sno white, an acrylic latex elastomeric compound sold by Dewitt Products. this link takes you to a short description of the product.

Clicking on the number 306 at the left of the description will get you more information on the product, but it dies not discuss anything about toxicity in the cured product. Nor does it mention use of it on iron or steel.

Contacting the company would seem to be in order. There are link which will take you to their home page at http://www.dewittproducts.com

Another company with similar products is Texcote.

Here is something else you might consider:

Also, epoxy coatings are suited for potable water once they have cured. They would probably stick better to pipe, too.

Finally, look at Ames products.

They have 4 products on this page which they list as being potable water compliant. One of them, Iron Coat, is designed to cover metal. This may be something you would be interested in. They invite e-mails, and you can find their MSDS (Material Safety Data Sheets) in .pdf form linked to the product descriptions on their web site.

Hope this helps.

I'm just curious: How did you manage to come to a kayak site for information on coating pipes?
