For this application assuming the MDF is clean, dry, sound and prepared as detailed in the technical data sheet we can recommend HMG Pre Cat Primefast 2014-04 followed by HMG Acid Cat MB Colours.

This is available in many RAL and BS colours in a matt, satin or gloss finish.

Prior to application do not scuff or roughen the MDF as this will release waxes in the MDF which could affect adhesion.
