    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

    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
