I have a small project that needs epoxy to bond one section.
Unfortunately, the area where the epoxy needs applies is narrow.Â* The
last time I tried it, I attempted using a cut off syringe, like
diabetics use, except the needle was cut off and the cylinder cut away
until is was maybe 1/8 to 1/4" thick.Â* Unfortunately, I was not able to
draw any of the mixed "5 minute" two part epoxy into the syringe as it
was too thick.

The epoxy I'm using is just the small, twin cylinder type that premixes
in either a small tray as part of the package or in something else.Â* I'm
just wondering what I can do to lessen the viscosity without
compromising strength or other properties when dried.Â* I was just
thinking of putting the package under a heat lamp set at like 110 F for
a couple of hours.Â* Thoughts and experiences welcome and thanks in advance.


There are thinner epoxies intended for "coating" that would probably
work, but AFAIN they are not available in tiny quantities. It it a
material than superglue might work for?


Ace sells some in 2 bottles that makes about 6-7 oz total. It is about
as thick as maple syrup and does a pretty good job of penetrating
cracks if you work it in with a plastic putty knife. Sometimes I will
use a mix of thick and thin epoxy, using the thin to coat everything
and adding the thicker stuff, even the paste to build up the area.
I have fixed those carbon fiber radiator end caps in two cars doing
that and using a couple layers of aluminum window screen to give it
tensile strength. It lasted years until I got rid of the cars.
