Beware of long-term storage stability issues if you combine TBAc with some amine and polyamide curing agents.

On the subject of coating storage is there any hard data on the effects of temperature extreme on coating performance including CD results?.The 40 -90 F ranges preferred can be easily exceeded during transportation say to - 20 - +120F depending on which month and which end of N America we are working.

I donot know of any data of storage stability temp vs coating performance. I do agree with Tom regarding stability problems of TABc with amine bearing compounds.
