Mipa silicone remover in liquid or spray format removes wax, grease and silicone before sanding, primer or topcoat work. Clean panels make the next layer bond to the surface instead of to contamination.
Guided machine part coating
Galvanized machine parts need careful cleaning, light abrasion and a suitable adhesion primer before the semi gloss topcoat. Zinc coated parts need an adhesion focused preparation method, not a quick coat over a smooth shiny surface. The specified Mipa products combine silicone removal, sanding, Mipa Active Primer with WPZ hardener, and PU 250-50 with A60 hardener and 2K thinner.

MP Sanding Pad helps abrade small covers, brackets, housings and edges before primer. A clean mechanical key gives the adhesion primer a better surface to grip.
Mipa Active Primer with Mipa Hardener WPZ is a chromate free 2K wash primer for non ferrous metal. It creates the adhesion bridge before the polyurethane finish is applied.
Mipa PU 250-50 is a semi gloss 2K polyurethane acrylic topcoat for machines and constructions. It suits small industrial parts where a tough, controlled finish is needed.
Mipa PUR Plus Hardener A60 cures PU 250-50, while Mipa 2K Thinner Normal V 25 adjusts application viscosity. Keep these products with the topcoat stage, not the wash primer stage.
Remove grease, processing residue, dust and handling marks with Mipa silicone remover before any sanding or primer work begins.
Abrade the part evenly with the sanding pad, reaching edges and fixing holes without rounding important details or damaging the part.
Use Mipa Active Primer with WPZ hardener on the prepared bare surface so the coating build starts with the correct adhesion layer.
Coat with Mipa PU 250-50 using Mipa PUR Plus Hardener A60 and Mipa 2K Thinner Normal V 25 according to the chosen application method.
Let the 2K coating cure before bolting, clipping or sliding the part into service because contact marks are easiest to create while the finish is fresh.
Clean, lightly abrade and apply Active Primer with WPZ hardener before the PU 250-50 finish.
Remove white oxidation and loose residue first so the primer bonds to a prepared surface rather than powdery contamination.
Use controlled sanding around holes, bends and cut edges because these areas often expose steel or lose coating first.
Do not sand through the zinc layer aggressively. The goal is a clean adhesion key and compatible primer foundation, not unnecessary removal of the galvanizing.
