non-toxic high-temperature non-stick paint

Dec 07, 2013 9 Replies

Hi all,



Where can I procure some small amount of the above substance for a bread maker whose 'stirer paddle' (made from cast iron by the look of it) is losing its coating?



cheers,



cd.


Areldite? Not sure what temperature it can stand.

He did say non toxic, and i was always told that epoxy was toxic.

I assume the manufacturer has no spare bits?

One hopes the old paint was non toxic as you have obviously been eating it.

You can't. Best bet is polish it as best you can. A bit of cast iron or more likely cast aluminium won't do you any harm and most times will still come out of the bread. Blunts the knife a bit if it doesn't.

2 options...
  1. Buy a spare part (easily available for Panasonic bread makers).
  2. Take the paddle out after the knock-down stage, which is what I do when I remember at the appropriate time. On my Panasonic bread maker, that's about 1 hour before the end of the program, and well before the bake starts.

At 16 years old, mine is not as non-stick as it was at new, but it still comes out OK even if I leave it in the bread until the end of the bake.

If its non stick, one used to be able to buy a 2 part curable ptfe coating. However, it did need to be baked on and also a degreased item able to stand high temperatures was required. I seem to remember this baking was much higher than the cooking for obvious reasons, and the undercoat or first part had some kind of etching action to bind to the material. PTFe is by nature extrememly slippery, so to get it to bond is quite a clever process I understand. Brian

If you don't want to buy a new one, the *key* question is what material the paddle is made from. That determines whether "polish" is an option. Different PTFE sprays may be suited to different substrates.

If it's not magnetic then it is probably an aluminium alloy. If it is, it is steel (but it could be tin or perhaps zinc plated).

I can't think of any ovenware which has zinc components/sufaces - at least not in direct contact with food.

Nor can I (although you used to get zinc bar-tops and I think kitchen work surfaces in France). If you were designing a steel paddle to be coated with some sort of PTFE you might *possibly* want to make it corrosion resistant in case of pinholes / chips / cracks. But I agree, zinc is not an ideal candidate because of its slight toxicity and solubility in acidic solutions.

These two are "food rated"
