Hello from really sunny England, I could do with some help guys, could anybody on here tell me if it is possible to create resin infused MDF board with a metallic substance in the composite.  I am working on a project and am interested to know if it would be possible to add magnetic particulates to the resin before infusing the MDF.  And if so, would this be a costly affair on top of the resin infusion ie would your require different machinery etc???

Thanks in anticipation.

You CAN get MDF to absorb quite a lot of infusion resin, just like wood can be "stabilized" by soaking it in Infusion Resin in a vacuum.  I use that a lot to make "stabilized wood" for knife handles e.t.c.

BUT! .... You would need EXTREMELY fine iron particles to get them to "follow the resin" into the MDF.. I've had even pigments stay on the surface of certain types of wood, effectively being "filtered" from the resin by the size of the pores.
