Do any of you know the shelf life of ROD BOND?
My ROD BOND that I've only had for a couple of years now isn't as smooth out of the bottle as I originally got it. It doesn't have the "Petroleum Jelly" smooth consistency any more. It's more chunky now. It still blends well and I checked my handles and still holding strong. Should I be concerned? Thanks, TONY Re: Shelf Life of Epoxy?????

Tony,
I am not the expert here. I can tell you I have some the same way and have been using it on several rods. It seems as if it is well mixed the chunks break up. i have not had any problems either. Bill Ohio Rod Builders Canton, Ohio Re: Shelf Life of Epoxy?????

There is no appreciable shelf life - it will last forever.
Warm the resin in the micro wave for a couple of 10 second bursts to return it to the original smoothness. Keeping it in a warmer area will help prevent crystallization of the resin. ............... Re: Shelf Life of Epoxy?????

Tony with Rod Bond there is no reason to nuke it, just use a spatula or popsicle stick and stir like crazy, comes right back to jelly consistency. Re: Shelf Life of Epoxy?????

In general terms epoxy components do have a shelf life
The long chain epoxy components ( the thick jelly & paste ones ) have quite a long shelf life The short chain epoxy components ( the runny ones ) have a short shelf life. with warming & or agitating they all smooth out and create a good bond in use. The bond you get in that situation is only slightly reduced in strength compared to fresh components. The big difference is in the free surface of older epoxies as they react & set. In contained molded situations eg reelseats, corks etc this is not an issue. In aged runny epoxies with large free surfaces they tend to 'orange peel' the free surface as they react and set. Warming increases the rate of aging..............its a short term fix with a longer term price. And yes, I warm my epoxies when they age & start to either precipitate or stiffen...................up to a point. Sorry, only registered users may post in this forum.
