Acetone dissolving Aeroglaze Z306 on astronomical gear

2004

We are building an infra red astronomical instrument and using Aeroglaze Z306 with 9924 wash primer to paint black aluminium parts (6061-T6). We have had a strange problems with this paint - after painting and curing the paint dissolves when we try to clean the surfaces with ethanol. This should not be the case since the manufacturer claims that the paint is acetone proof after curing. All procedures recommended by the manufacturer were followed closely.

Does anyone have a suggestion or advice.

Thanks

Clean it with acetone Acetone [affil link] instead of ethanol. If it dissolve in acetone when the mfg. says it doesn't THEN raise a ruckus with the mfg.
