PTFE micronized wax has been a quiet standard in coatings and inks for a long time. A small loading gives a finished film lower friction, better scratch and mar resistance, and a smooth, soft surface. It does its job without much attention, which is part of why it ended up in so many formulations.
That is changing. PTFE is a fluoropolymer, and it sits inside the broad regulatory definition of PFAS that authorities in the United States and Europe are now restricting. Formulators who have relied on PTFE wax for surface performance are being asked to find an additive that holds the same properties without the fluorine. This article covers what that replacement looks like and how the organic chemistry behind it works.
What the PTFE additive was actually doing
It helps to separate the term from the function. In a coating or ink, a PTFE micronized wax is a surface additive. It migrates to the air interface of the wet film and sets up a slip layer at the surface. That slip layer is what you feel as a low coefficient of friction, and it is what protects the film against scratching, marring, and rub damage during handling and use. In a soft-touch coating, the same surface effect gives the warm, matte feel that premium packaging and automotive interiors are built around.
So the job to replace is specific: surface slip, scratch and mar resistance, and tactile feel. An additive that delivers those three properties replaces the PTFE wax, whatever its underlying chemistry.
Organic polymethylurea as the replacement
The chemistry that has emerged as the practical answer is organic polymethylurea, usually written as PMU. PMU is a micronized organic thermoset. It is the same family of chemistry that has been used for years as an organic matting agent in industrial coatings, where its particle structure takes gloss down without the downsides of silica.
As a surface additive, micronized PMU does what the PTFE wax did. It lowers the coefficient of friction, adds scratch and mar resistance, and produces a soft, matte feel. The difference that matters for a 2026 formulation is that PMU contains no fluorine, so it falls outside the PFAS question entirely.
There is a second benefit worth noting. Because PMU is also a matting chemistry, many PMU surface additives do two jobs at once. A single additive can reduce gloss and add slip and scratch resistance, which can simplify a formulation that previously used a separate matting agent and a separate slip wax.
Where it works
PMU surface and matting additives are formulated for a wide range of systems. They run in waterborne, solventborne, and solvent-free coatings, air-drying or stoving, and they hold up in UV-curable and radiation-cure systems where many additives struggle. Common homes are:
- Industrial wood and furniture coatings, where a soft, low-gloss, scratch-resistant finish is the target
- Soft-touch and haptic coatings for electronics housings, automotive interior parts, and premium packaging
- Printing inks and overprint varnishes that need rub resistance on the finished print
- Two-component polyurethane topcoats and coil coatings
- UV and energy-cure inks and coatings
How to approach the switch
Two points keep a PTFE-to-PMU change on track. First, match the additive by the property you need, not by the old product code. Decide whether the priority is slip, scratch resistance, soft feel, gloss reduction, or some combination, and pick the grade that targets it. Second, trial it in the real formulation. Surface additives interact with the binder, the cure, and the other additives in the can, so a quick lab panel tells you more than any spec-sheet comparison.
A note on documentation
PMU is an organic urea-based thermoset, and some buyers will ask about that chemistry during review. The right move is to put the additive's Technical Data Sheet and Safety Data Sheet in front of the people running the regulatory check, so the composition data is in hand. That is a normal part of qualifying any new additive.
Where to start
If your formulation runs a PTFE micronized wax today and you need a path off it, the organic PMU additives are the place to begin. P.A.T. Products distributes Deuteron's PMU surface additives and matting agents across North America. Tell us the system you are formulating, the surface properties you need, and the PTFE additive you are replacing, and we will recommend a grade, provide a cross-reference, and send a sample.
