Adhesion of epoxy to guidewrap

I just posted (2) photos in the guide wraps section of photos showing peeling of epoxy from wraps.
This never happened before; the wraps were completed (1) year ago, fished hard all year, and now brought back to refurbish. Why no adhesion of epoxy to thread?

NCP? Nylon? Did you use CP?
Is there epoxy penetration under the wraps? ----------------- AD Re: Adhesion of epoxy to guidewrap

Nylon.
Yes, CP, but I don't remember what I used at the time. NO penetration under wraps; again I don't remember the brand. Completed in shop at approx 70° F "It ain't what you don't know that gets you into trouble.It's what you know for sure that just ain't so."

John, I have rods that are thirty years old that I used Flex Coat CP and they still look good. Maybe the CP was not completely dry before you added the epoxy. Just thinking... Re: Adhesion of epoxy to guidewrap

Possibly CP??
Anybody else have a problem with no adhesion after CP? "It ain't what you don't know that gets you into trouble.It's what you know for sure that just ain't so." Mark Twain John in Wethersfield, CT Re: Adhesion of epoxy to guidewrap

John, did you do all the colors of threads the same way? And is it only the black threads having this problem? Re: Adhesion of epoxy to guidewrap

Hi,Jim,
Only the black thread has this problem. The blue u'wrap is Madeira® with (2) coats of CP, then black nylon guide wraps with (2) coats CP, then (3) thin coats epoxy. I've used this black thread before and after this occurence with no problems. This is a real puzzle! Note: the pink rod was for a guy's wife, known as "the striper queen". I gave the paint shop a bottle of Pepto-Bismol® as a color reference; maybe that was a bad sign!!

John, That looks like moisture got into your wraps. I see that your guide feet are not fully encapsulated . How well did you fill the tunnels? Dennis J. Danku (Sayreville,NJ) Re: Adhesion of epoxy to guidewrap

After further investigation, I might not have filled the tunnels as well as I should have.
Would it look like this if I inadvertantly skipped the CP? The thread is National "D", which has never given me a problem before.

John,
From the pictures I would guess that you used an acrylic cp, and did not enclose the tunnels with epoxy; I say enclose, because even though you might have filled them with cp, not fully enclosing them with epoxy would have left some cp exposed to moisture, which would in turn have caused it to soften possibly causing the epoxy to pull away from the wraps in that area. If it were me, I would re-wrap the black, not use cp, and finish like normal. Chris Herrera Re: Adhesion of epoxy to guidewrap

Chris,
That's exactly what I'm about to do this morning. Thanks "It ain't what you don't know that gets you into trouble.It's what you know for sure that just ain't so." Mark Twain John in Wethersfield, CT Re: Adhesion of epoxy to guidewrap

John I asked if the threads were all finished the same way just to make sure this was a problem with the black alone.
But now, seeing as this is a woman's rod. I am wondering if perhaps she applied some nail polish to the guide wraps to "fancy" them up a little bit and didn't like it and took them off with nail polish remover Re: Adhesion of epoxy to guidewrap

CP isn't the problem. Something is wrong with thread or something got on it prior to finishing.

I would agree with the tunnel suggestion. It looks like the underwrap is clean, like the epoxy didn't make it in there through the tunnel for some reason. David Dosser Coshocton, OH Re: Adhesion of epoxy to guidewrap

Listen to Tom something was either in the thread or contaminated it prior to finish Re: Adhesion of epoxy to guidewrap

The CP could have went past the actual finish??? I did that on a personal rod and moisture got inside the wraps quick. just a thought. But a year later of hard use.... dosent sound right. As tom said, something more than likley got on the wraps before finish was applied. Edited 1 time(s). Last edit at 04/05/2011 03:50PM by Garrett Adams.
