epoxy question

[Clive S]

- Simple seperation from scaled steel surface.
- Simple seperation from grinded steel surface.
So ... I need to be carefull when removing unwanted material.
Did any of you prime the steel with a coating to prevent easy seperation?

Did you make sure that the surfaces were clean and free of any oil deposits. I have used the West system with no issues and the epoxy bonds well to the steel.

I also used West System, ground back the surface a little and it was fine. Make sure you have the ratio correct and mix mix mix!

well made sure... degreased with brake cleaner.. wipedown and brake cleaner 2 times before grinding...

maybe use paint thinner or amonia or something else...



the test was done with 20gr resin + 8 gr hardner.... bigger volume will give me better resolution (1gr precision scale )

To be honest I never tried it with such small quants just went straight for the big pour! But it worked fine.
