Thickened Epoxy and Syringes

[Captain Smollett]

Found out today that WEST epoxy resin thickened with their 403 Microfibers does NOT work with syringes to squirt into small places.  The microfibers plugged up the orifice allowing purer resin to squirt through until the orifice became completely plugged.

So, I ended up mixing thinner than I normally would like so it would pour.

Been using 406 Colloidal Silica for a year with no problem.  This has allowed me to inject a thicker mix.

The syringes I am using are 12 ML Monoject syringes I got in bulk from a horse vet.

I have never had much luck with injecting epoxy, but have come up with some work arounds...

where were you injecting it?

LOL- nope- you ain't gonna inject microfibers-makes way to thick a mix. But you can use a baggie with the corner clipped off, or a cake decorating syringe. Big opening of course.

Microfibers are more for gluing two parts together- holds the epoxy in the joint. I wouldn't even attempt to inject that mix.

Craig:  I use the syringes to fill old screw holes and other small places like that.  This way, I can mix (with 406) it thick enough to not sag.  This time, I was filling around the core-cell on the recoring project, and between pieces of coring, I left a gap 'just big enough' for the tip of the syringe...hoping to make very short work of squeezing some into the gap.

I ended up mixing the 403 a bit thinner and just 'spooning' it in with a flat stick.

CJ: Yep, now I know.  I'll try the zip-lock bag with a corner cut off; that's sounds like a good idea.
