Baking parts in kitchen oven

Hey I'm single and I can get away with it! Also, my above-oven exhaust fan vents outside of the house.
I baked a knuckle at 225*F for 80 minutes and I could only smell paint if I was standing next to the oven.
Two feet away and I couldn't smell a thing.

Anyhow, my question is for the SPI expoxy.... is there a recommended temp and baking time?
I read that some people will bake parts, let them cool, then repeat bake/cool a couple more times afterwards.

My fingernail with medium-heavy pressure was able to put a scratch into the expoxy after baking/cooling.
So, I thought I'd ask whether I'm doing it right or not.

No automotive refinish products are supposed to be baked that hot. Most are 140-160 metal temperatures for 20-30 minutes. Epoxy dries very slowly. Heat will get it out of the "going dormant phase" quicker, but full cure is still going to take a long time (months).
 
Why are you baking?

Edit, on my 1995 Lightning I epoxied just about everything under the truck, never baked any of it.

If you were married, I suggest an excellent divorce Lawyer, but since your single, to be honest just not sure how safe this is, and the sun is safe for sure.

I was thinking about this as you said 2 feet away, you could not smell.
My most significant risk in the manufacturing part, and I have twice to 3 times the airflow required, is not smoking over a 300-gallon batch, but dropping something on the floor to cause a spark.
(No smoking in our building, just an example.)

Year's ago, a paint company lost a half square mile of their plant when
A guy on an electric forklift penetrated a stainless tote with the forks, no big deal, but he panics and let the forks slam the floor, all gone bye-bye.
 
key word is metal temperatures and household oven so you need to consider your thanksgiving turkey baking at 350 for 6 hours to get to 160 meat temperature. I am guessing your parts got up to about 120-130 in 80 minutes.

For the most part, the only reason automotive refinish products are not supposed to be baked over 140 degrees is the toners start to discolor over 140.

Not that I recommend it, or ever baking food in that oven again.
 
The real problem with using an oven is the exposed flame or heating element, confined space, and the solvent gassing out of the work piece. You are very fortunate your oven didn't go BOOM!:)
 
anyone know if them exhaust fans over an oven are explosion proof type fans?
that sure would be a way to get a fire spreading quicklike- get it into the attic. got some nice intake and exhaust up there.
