Deuteron® PMH M is a micronized deuteron plastic powder derived from PMU (polymethyl urea). This micronized matting plastic is characterized by a compact particle structure and possesses heat resistance up to 200°C. It exhibits a minimal impact on viscosity and acts as a synergistic component to enhance the polishing and burnishing resistance of SiO₂.

Chemical Family: Polymethyl Urea

Functions: Flattener

End Uses: Solventborne Coating, Waterborne Coating

Labeling Claims: Biodegradable

Features: Abrasion Resistance, Blocking Resistance, Burnish Resistance, Excellent Scratch Resistance, Improved Chemical Resistance, Improved Mechanical Resistance, Matting, Polishing Resistance

Product Highlights
  • Deuteron® PMH F and Deuteron® PMH M are micronized duromeric plastic powders based on PMU (Polymethyl urea).
  • The unique synthesis of Deuteron® PMH matting agents leads to a well-balanced mix between compact and amorphous particle structures – this property makes them good matting agents with very low influ- ence on viscosity and porosity. Because of their highly compatible chemistry Deuteron® PMH matting agents can be used as matting agents in a wide variety of different applications and systems.
  • Compared to the Deuteron® MK family our Deuteron® PMH matting agents shows less matting efficiency but signifi- cantly less influence on viscosity and improved flexibility.

Application and Dosage Information

Deuteron® PMH matting agents can be used in almost all coating applications ranging from water borne and solvent borne to 100 % systems. They can be used as stand-alone additives or in combination with other ma- terials to further improve their properties.

The use of Deuteron® PMH F and M especially improves the following properties:

  • Good matting effect
  • Very low influence on viscosity
  • High mechanical and chemical resistance
  • High scratch resistance and resistance to polishing
  • Temperature resistant up to over 200 °C, short- time up to over 300 °C
  • Pleasant touch
  • Improved blocking resistance
  • Insoluble in solvents commonly used in paints
  • Biodegradable


  • Typical addition range: 1 %–15 %
  • The required dosage level highly depends on the system (e.g. binder type, additives, solvent content) and appli- cation parameters. Thus, it is highly recommended to determine the needed addition level by a practical ladder study.


  • The PMU chemistry in general is highly compatible in a wide range of systems. Due to that Deuteron® PMH mat- ting agents can be incorporated easily by a high-speed stirrer without the need for specific wetting agents or dispersing aids. They are shear stable in high shear pro- cesses but should not be ground in a bead mill.
