MDF dust as filler?

Post by Dan_Smullen » Wed Sep 18, 2019 9:10 am

Would the fine dust produced from MDF on a cnc be a suitable replacement for wood flour?

No, I would not use MDF Dust. Stay with the wood flour. Jeff

I wouldn't use it either. I wouldn't trust the glue and wax they use in the manufacturing process mixed with epoxy to create a structural joint.

My preferred filler is aerosil or cabosil.

I have used ground corecell, which is out of the box from convention. I tested it and found it to be a sort of flexible filler that bent before it broke. One of the attribites of corecell M is it is highly heat resistant, so I used it where I needed a high volume of filler. Fortunately, we had no fire!

If you go away from convention; testing is needed.
