Letter 11789 Vinyl coating on metal???+ We have a metal tubing that needs to be protected with a colored vinyl coating. Who makes that kind of products and how do you find a supplier? What kind of process is it, dipping, painting? heated on? Thanks, Jean-Francois Cote
+ It sounds like you are referring to plastisol coating. This is usually done by a dipping process onto a properly primed substrate. Although there do exist air-dry plastisols, the better plastisols are oven cured. Any plating rack manufacturer would have plastisol dipping capability.
+ Hi Jean-FranÁois! Re your question, WHY vinyl, why not other 'coatings'? Why the colouring? What's the environment? The most expensive but the toughest coating is called PLASTISOL. This calls for a liquid PVC monomer into which one dips the product, then lets it drip 'dry' for a short while, then one puts this into an oven to cure. Tough, resilient, very acid/alkaline resistant coating. Not a smooth, perfect finish and far thicker than paint. As far as paints are concerned, ask your local paint people. They would have a far better colour choice but not necessarily vinyl! Hope that helps you un petit peu.
+ Here in the U.S. I know its possible to have vinyl dyes custom blended if this is what you're looking for. Specifically what I have had done recently was a combination system. It was a Dupont branded vinyl dye in a Sherwin-Williams packaging aerosol system. Spray on just like spray paint, I'm sure something like this can be formulated in larger quantities and packaged more accordingly to your needs. Consider contacting Sherwin-Williams Automotive division if this sounds like the product that might be of help to you. Its nowhere near as thick as a plastisol coating. Its very thin, dries quickly and can be blended in a very wide range of colors. Just offering you another option in case the plastisol coatings aren't exactly what it is you were talking about.

October 13, 2007 I'm looking for some sort of service like this myself, I want to
have some tools like spanners, screwdrivers etc insulated in some
sort of soft grip PVC or vinyl, anyone got any suggestions? Who Jang
March 10, 2009 My company is buying galvanized and stainless steel metal stamped parts in China. We have the parts vinyl-dipped, but the dip is not "tight" -- it does not adhere to the surface of the metal. Our supplier checked with his vinyl dip subcontractor and was told that in order to achieve the tight dip they would need to first coat the part with an adhesive and oven-dry it before applying the vinyl dip, and that this would add 40-60% to the cost. Does this sound right? Any suggestions on how to achieve the tight dip without such a huge cost increase? Any advice is appreciated. Hank Sheller
March 10, 2009 Hi, Hank. The principle is correct. I can't comment on whether the surcharge is in balance. Regards,
