  • Heat Resistant Paint - How is Stove Paint different?

    How does heat resistant paint marketed for BBQ and Stove
    applications differ from that sold as general purpose high-temp
    applications when both have the same operating peak
    temperature (say 1,200؛F or 649؛C) ?

    I am aware that there are other HT finishes that are said to
    withstand up to 2,000؛F.

    Food safe requirements would be my first guess. Not outgasing after initial curing.

      Perhaps, but I'm not so sure.

      I have a can of Krylon BBQ & Stove Paint. Instructions on the
      can give applications as BBQ's, grills and wood burning stoves.
      Further down, there is the admonishment "Not for Use on Kitchen
      Stoves". Maybe reflecting an intention for outdoor use, not indoor?

      Also, there may be a difference in the application severity. While
      the Krylon BBQ & SP is advertised as rated for 1,200؛F, fine print
      on the lable qualifies this by advising it withstands temp spikes to
      1,200؛F, but is rated at 600؛F for sustained periods.

      There is no such qualification on cans of Würth's High-Temp Spray
      Paint rated for 1,200؛F.

      The attraction for stove paint is the smooth, black, semi-gloss
      finish it lays down. The Würth, VHT and other high-temp products
      I have tried deposit a rough textured finish that is somewhat gray
      in appearance.

        Flame contact? With a BBQ or wood burner, you have it. An oven or kitchen stove, you do not. Heat resistant is not the same as flame resistant.

          Hi Eddy,
          Here in the UK I've used Sperex VHT quite often, it's a stoved (not stove) enamel and oncce touch-dry requires an hour or more in the oven to cure and harden properly, while BBQ paint is just spray and wait...

          The VHT finish once cooked is satin and defnitely black, not grey, but like any paint the underlying finish makes a big difference to the final result - it needs to look good in the bare metal then have the surface lightly keyed for adhesion (for motorcycle aluminium parts I give 'em a quick swish in NaOH solution, steel gets a fine grit blast).

          The smell from the oven disperses after the first 10 minutes or so - I suppose the remaining solvents outgas pretty quickly? It won't make cakes taste too good if they go in with it though...

            How about header hi-temp paint, that always seemed to do the trick & near the engine block the headers get quite hot.
