How long before removing clamps after gluing?

[lakeracer69]

I'm using Poxy grip and usually let things set up for 24 to 48 hrs before unclamping. I'm doing a number of laminations for my sheers and have some highly stressed areas within each lamination. I don't want to have a disaster by removing clamps too soon. I also don't want to add unnecessary time between lamination applications. I'm probably going to wait 48 hours, unless I hear something else to the contrary.

Does anyone have any idea as to when Poxy grip or applicable epoxies reach a 90% curing strength?
It would be nice if I could get away with a little less time between laminations without having a disaster.

Thanks

I have used Poxy Grip to great success. If the area is under a lot of strain, I would wait 48 hours.

Nooooo! 48 plus seems to be working out. : )

I've never had a problem after 24 hrs.

Depends on your room temperature. The only time my epoxy separated after I removed a clamp was the time I forgot to turn on the heater in my garage during winter. Colder temperatures slow down the cure time. Room temperature should be fine after 24 hours in most cases.
