Q: I had just had a smoker powder coated for barbequing. They coated the inside of the smoker (which they were not supposed to do).
At what temperatures is regular powder coating safe? Are there any fumes that would be released at any certain temps? I am just wondering about general safety. Temps don’t reach more than 300°F in the smoker.
A: Without knowing the exact formulation and its composition, I can’t unequivocally say that nothing will volatilize from the cured powder. That said, I can assure you that the powder coated interior is safe and will not contaminate your smoking process or the products you smoke within it, especially if the surface temperature never exceeds 300°F (150°C).
Powder coatings do not generally degrade until around 425-450°F (218-232°C). Silicone-modified powder coatings can typically endure 800-1,000°F (427-538°C).
