View Full Version : Epoxy for leveling of linear rails

Hi I was looking for Epoxy to level my linear rails. I came across Reckli Epoxy pb. It has a viscosity of 230 mPa/s. It's cheap 13€/11GBP per kg.
Do you think it's worth a try?
Thanks a lot

Most of us use the West Epoxy system, which is quite common. The 105 resin with the 209 extra slow hardener is the way I'm going with mine - but it costs about 5-6x times the version you've posted.
Theres a rather good discussion of the topic here:

Hey yes I know the thread. But the 105/209 has a way higher viscosity with 600.
It just has a bit longer cure time which may give it a bit more time to settle

On my routercnc YouTube channel I had a few goes at mixing and laying the West epoxy. You can see what is involved and how it turned out. Here is Episode 15

Also in Ep 17 and a few episodes later for the Y rails. This may help decide whether to go with the West system or not.

Yes I followed your episodes interested. But I wouldn't have heated the epoxy beforehand. West system recommends heating the surface rather then the epoxy. But I wouldn't do it at all as heating and cooling brings shrinking I would say.
I was thinking to test my built channel with ethanol for leaks.
I think I will give it a try with the epoxy I found it's nearly a third of viscosity. And price seems to be fair too

Easy Composites IN2 is also very thin and very slow. The quoted demould time of 24hrs is more like 36+ in my experience. Disclaimer: I have no experience using it for levelling things.

Yes but still 600 compared to mine having 230

IN2 is 200-450MPa.s mixed @20'C.

In my opinion the shrinkage is also important

Yes shrinking is definitely important. To my understanding it mostly results from elevated temperature while curing. I think the factors to minimize it is:
Slow curing Epoxy
Low temperature
Adding a filler like silica/chalk
But point 2 will result in a higher viscosity.
And 3 in uneven surface
