Polypropylene and polyethylene are among the hardest materials to print: their smooth, low-energy surface makes ink bead up and then flake off at the first rub. Marabu Primer P2 solves the problem before you even start printing.

Ink that sticks to PP, PE, metals and powder coatings.
A clean surface: it degreases and prepares the substrate in a single wipe.
Consistent runs: no more parts rejected for poor adhesion.
Versatile: works with Marabu screen and digital inks, and with other inks too.

● ● ● The problem

Why ink beads up and flakes off polyolefins

Polypropylene and polyethylene have a very low surface energy. Add fingerprints, dust or invisible additives left over from manufacturing, and the ink has nothing to grip: it retracts, beads up or peels off after curing.

The problem isn’t the ink or the printer — it’s the surface. Primer P2 takes care of it before you print.

● ● ● The solution

What Primer P2 does

A liquid adhesion promoter based on chlorinated polyolefins, P2 creates an interface between the substrate and the ink layer. Marabu designed it for manual pre-cleaning and pre-treatment of PP and metals; it also improves adhesion on powder-coated surfaces.

Uniform results

Irregularities caused by surface contamination disappear.

Less waste

Adhesion is there from the very first part, even on notoriously difficult substrates.

A simple routine

Apply, let it flash off briefly, print.

No lock-in

Works with Marabu screen and digital inks, and with other ink brands too.

● ● ● How to use

Four steps, one cloth

01A clean, dry substrate

Free of grease and fingerprints.

02A thin layer

Apply P2 over the whole area to be printed with a clean, lint-free cloth.

03Let it evaporate

Wait for the solvent to evaporate before printing.

04Validate on a sample

Adhesion depends on the substrate / ink combination: test before a production run.
