[NSRCA-discussion] Epoxy Removal

[Gray E Fowler]

On cured epoxy solvent will not work....before it damages your covering. 
Most likely you are using an epoxy that you bought at a hobby store or 
similar. At about 130F it will be above its glass transistion temperature, 
which means it will become rubbery and lose much of its adhesive 
characteristics. Take a covering iron, heat the epoxy directly with the 
iron and while it is hot you should be able to remove the epoxy much 
easier with your razor blade. Epoxy is a  "thermoset"  reaction so 
contrary to most peoples opinion, it will never melt nor dissolve with 
heat or solvent.

[NSRCA-discussion] Epoxy Removal






Hello all,

Is there any way posible to remove old dried epoxy from covering without 
damaging it besides trying to pick it of with a single edge blade or #11 
blade. It doesn't stick to covering like it does in wood but the blade 
leaves scratch marks on the covering. Any ideas, anybody???

Thanks,

Ken
