I used 5200 fast set (24 Hours) and noticed I was able to peel the old stuff off the hull when I re-glued my foam foot rests. Is this stuff less adhesive then the regular 5200? cya Bob Denton *************************************************************************** PaddleWise Paddling Mailing List - All postings copyright the author and not to be reproduced outside PaddleWise without author's permission Submissions: paddlewise_at_lists.intelenet.net Subscriptions: paddlewise-request_at_lists.intelenet.net Website: http://www.paddlewise.net/ ***************************************************************************
Hi Bob, I'm not qualified to make a knowledgeable comment on the fast-set stuff - I've never used it. I can say that the times that I've used 5200 it has appeared to be _permanent_ . In general, most fast-set adhesives are not as effective as their slower curing relatives. (OK guys, I'm a wide open target for making that statement) As when using just about any adhesive, I think that the surface preparation is the most important factor in the ultimate effectiveness of the joint.

Ditto here, except that I **have** used the fast-set 5200 to attach D-ring holders (PVC) to the inside of the hull of my fiberglass yaks, and that stuff is also permanent. I use 80-grit to roughen both surfaces, and a clean acetone swab to remove any oils (etc.). Bob, if the foam is delaminating from your hull after adhering with 5200, I bet the failure is in the foam, not the 5200. -- Dave Kruger Astoria, OR chemist *************************************************************************** PaddleWise Paddling Mailing List - All postings copyright the author and not to be reproduced outside PaddleWise without author's permission Submissions: paddlewise_at_lists.intelenet.net Subscriptions: paddlewise-request_at_lists.intelenet.net Website: http://www.paddlewise.net/ ***************************************************************************

Do I have that right? If so, I suspect surface preparation is the culprit. Even the fast-set stuff is incredibly adherent, in my experience. -- Dave Kruger Astoria, OR chemist *************************************************************************** PaddleWise Paddling Mailing List - All postings copyright the author and not to be reproduced outside PaddleWise without author's permission Submissions: paddlewise_at_lists.intelenet.net Subscriptions: paddlewise-request_at_lists.intelenet.net Website: http://www.paddlewise.net/ ***************************************************************************
The failure was partly the original hydrogrip which then increased the stress on the remaining foam which split. I reglued the foam to the hull and also repaired the split. It seems pretty secure now. I'm going to give it a workout after work.. If it fails again, I'll opt for the pegs. cya -----Original Message----- From: owner-paddlewise_at_lists.intelenet.net [mailto:owner-paddlewise_at_lists.intelenet.net]On Behalf Of Dave Kruger Sent: Thursday, May 18, 2000 2:41 PM To: PaddleWise Subject: Re: [Paddlewise] 5200 Red "Seng, Dave" wrote: > I'm not qualified to make a knowledgeable comment on the fast-set stuff - > I've never used it.

I was surprised, but yes, I was able to peel the old 5200 off the hull. I had cleaned it with acetone and roughed it up with 80 grit. cya -----Original Message----- From: owner-paddlewise_at_lists.intelenet.net [mailto:owner-paddlewise_at_lists.intelenet.net]On Behalf Of Dave Kruger Sent: Thursday, May 18, 2000 2:44 PM To: PaddleWise Subject: Re: [Paddlewise] 5200 Red Bob Denton wrote: > > I used 5200 fast set (24 Hours) and noticed I was able to peel the old stuff > off the hull when I re-glued my foam foot rests.
