Paint Peeling Inside drum

Postby all_grown_up » Tue Mar 24, 2009 6:28 pm

The paint on the bottom of the drum I use to centrifuge my oil is peeling up.

Can someone tell me why this is happening? Heat?

Is there a paint I should use on the inside of a drum that won't do this?

"your oil" is eating the paint.

I gather from the quotations around "your oil" that not everyone's oil eats the paint on the bottom of the drum?

Not all used vegetable oil is the same, nor is all paint the same. You asked what is causing it, and that's what I answered. I don't know anyone who uses interior painted containers for VO. We use bare steel or HDPE.

I have a about 20 45 gallon drums full of WVO.
All of them are painted inside.
That’s how I got them from a research lab for vegetable oil.
Some arrived with the paint scratched.
These I use for short term storage and I have not seen any negative effect over 4 years.

Did you paint the drum, or was it factory painted? I use a factory painted drum for my CF and it hasn't peeled at all.
