twbass Posted December 26, 2011 Report Share Posted December 26, 2011 (edited) Has anyone tried thinning the 30 minute 2 ton devcon? If so what did you do. Thanks twbass Edited December 26, 2011 by twbass Quote Link to comment Share on other sites More sharing options...
Lincoya Posted December 26, 2011 Report Share Posted December 26, 2011 Most people here that thin D2T use denatured alchol. I have used lacquer thinner in the past to thin it to shoot thru an airbrush as a clearcoat but you can't touch the bait until the D2T has cured or you'll ruin the paint job.

BobP Posted December 27, 2011 Report Share Posted December 27, 2011 I use denatured alcohol. Just a few drops is enough to extend the brush time by a couple of minutes and the epoxy will still harden "on schedule". Quote Link to comment Share on other sites More sharing options...
mark poulson Posted December 27, 2011 Report Share Posted December 27, 2011 I was told by an epoxy tech. tost be sure to mix the two parts completely before you add the alcohol. Otherwise, the alcohol will bond to one part of the epoxy, instead of the two parts bonding to each other, and the mix won't set up properly. 4 Quote Link to comment Share on other sites More sharing options...
RayburnGuy Posted December 27, 2011 Report Share Posted December 27, 2011 I mix my epoxy with a few drops of denatured alcohol like Mark described and have had no problems. Quote Link to comment Share on other sites More sharing options...
sambennett Posted December 27, 2011 Report Share Posted December 27, 2011 I have added the denatured alcohol prior to mixing thoroughly and had some problems with the epoxy fully curing in small spots. Not 100% sure that was the culprit, but it's all I could put my finger on. Quote Link to comment Share on other sites More sharing options...
Travis Posted December 27, 2011 Report Share Posted December 27, 2011 Never had any issue with adding solvent prior to mixing devcon. This has always been to coat molds however. Never added to coat crank. Quote Link to comment Share on other sites More sharing options...
littleriver Posted December 28, 2011 Report Share Posted December 28, 2011 I have tried before and after mixing . Worked for me both ways. I have to say though, why take a chance in messing up the chemistry if you do not have to? The only reason I sometimes have thinned before mixing the epoxy was to aid in mixing because the epoxy was cold. Once thinned a little it mixed easily even cold.

Arkie Posted December 31, 2011 Report Share Posted December 31, 2011 I also use denatured alcohol, and have been for years. 1 small to medium size bait = dime to nickel size epoxy parts and 4 - 6 drops of d.a. One thing I like about d.a. besides extending working time is that I can thin a mixed batch to achieve a thinner finish coat, which I prefer on many of the newer jerk baits that have molded scales, fins, etc. Not quite as durable but lighter in weight for such finely tuned (neutral buoyancy) out of the package baits. 1 Quote Link to comment Share on other sites More sharing options...
sallystrothers Posted December 31, 2011 Report Share Posted December 31, 2011 I will say what not to use... Acetone. I tried that and it inhibits the complete polymerization and results in a jelly. 2 Quote Link to comment Share on other sites More sharing options...
