What is the titanium non-stick coating on Kuhn Rikon pressure cookers? You can't see it.

  • 8

So I just bought a Kuhn Rikon pressure cooker. I open the manual and it states it has a "hard, highly resistant titanium non-stick coating". I look in the pot and it looks like it's all stainless to me. However, when I feel the bottom, it feels more slippery than my other pots.

Further on, it states:

"We recommend the use of plastic or wooden turners in spite of the
hard and very resistant titanium base coating."

I don't like using non-stick pots because: 1) I don't know what's in the proprietary blend of their coating and 2) If it can scratch and come off, it greatly shortens the prospective life of the cookware.

Does anyone know what this coating is? Everyone else that is selling titanium non-stick coatings have surfaces that are black or gray in color. I would like to know what this is on Kuhn Rikon's line of cookware.

  1. Titanium is a metal. If it is on the inside of your pot it would be almost indistinguishable from the appearance and feel of stainless steel. It would be very durable.

      Thanks kagemusha49. I am familiar with titanium as a metal. However, I was researching titanium non-stick coatings and was finding that in most cases, these coatings that companies called titanium were really a polymer compound and not the actual metal.

      I guess in this case, it actually is titanium since it is anodized and doesn't look like plastic. Thanks for your help.

        In a few cases I know, the titanium may be used, but it is not the nostick surface. Basically, a layer of nonstick Teflon with some ceramic titanium substrate for physical protection. Scanpan is known for it:

        "PTFE (short for polytetrafluoroethylene) is the base compound for any and all nonstick coatings. PTFE provides the food release. The SCANPAN formula works with the patented ceramic titanium surface construction to provide long lasting nonstick performance. This PTFE is safe to use for food preparation and is FDA approved. ....etc."

        1. re: Chemicalkinetics

          Yes, that is the kind of titanium non-stick surface I found the most information about. It is black and looks like the teflon (at least in pictures). I don't think it's all that different from teflon, just different chemicals.

          Check out the photo I attached. It just looks like a stainless steel pot inside. This must be the real deal. However I found it strange that they would suggest not using metal utensils. That is initially what sparked my concern.

           
    2. The online manual reads:
      "
      1.1 The additional advantages of your
      pressure cooker with non-stick coating
      In addition to the well-known features of KUHN RIKON pressure cookers,
      this coating offers you further decisive advantages:
      • Hard, highly-resistant titanium base coating
      • Non-stick coating (no difficult-to-remove food residues)
      • Quick browning possible
      • Simple cleaning
      • Multifunctional pan: crisp fry in the traditional manner, then cook until
      done under pressure (cooking time under pressure approx. a 1/3 of normal
      cooking time)
      "

      That could be interpreted as: some models, not necessarily yours, have a titanium ceramic based nonstick coating.

        Thanks for looking this up. I contacted the company and they said it is a PTFE (Teflon) based coating. They said they stopped manufacturing their products with this coating, but products still exist online and in retail stores with the coating. What's strange is that they sent me the latest manual and it still says it has a non-stick coating.

        1. re: mattspaeth

          The manual I found reads like it applies to a range of models. There are several other sections where there is a subsection about the nonstick models (e.g. frying with the nonstick PC).
