Mailing POR-15, what is flash point?
 

Hi,

I want to mail a 4 ounce can of POR-15. I know I meet the size requirement but the post office mention it had to below a certain flash point. Anyone know what it would be?

Thanks,

David

POR delivers by mail all the time. Why the concern?

Because I asked the person at the PO and she mentioned the requirements.

Thanks.

From their MSDS:

Thanks for your help. This is perfect.

It has to be above a certain minimum flash point, It it was below it would be deemed hazardous and unshippable.
