Good point, Bruce. In that vein, the 'expiration date' is close to a simple arbitrary number. In the large volume product we use, the manufacturer gives a 6 month shelf life statement....whether it comes fresh off the production line or has set for 6 month in their warehouse. A test coupon to check formulation and the viability of the polymer components should be done anytime components have set for a lengthy period of time (more than a few weeks, especial as you approach, or pass, the expiration date).

Well, good luck and hope your plane stays together. Wonderful news to learn of now. Would have been nice to know this yesteryear. ------Original Message------ From: marv@lancair.net Sender: Lancair Mailing List To: lml@lancaironline.net ReplyTo: Lancair Mailing List Subject: [LML] Jefco Sent: Apr 8, 2009 5:06 PM Posted for "Justin Hawkins" <JustinH@lancair.com>: All Lancair customers the build shop did a test on the Jefco resin, if it gets close to freezing even for only a matter of minutes the resin can crystallize and its properties ruined. So if that happens clean the pump replace the resin. The jefco resin in the 5 gallon drums if left on a concrete floor or steel floor the resin can pull the cold up into the container and ruin the resin. Make sure the resin is stored properly for long use. Justin Hawkins Lancair Airframe & Technical Support Lancair Int.
