Application and Dosage Information

Deuteron® MM 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® MM 682 especially improves the following properties:

  • Good matting effect due to the synergy effects
  • Very low influence on viscosity even at high application rates
  • 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 felling
  • Improved blocking resistance
  • Insoluble in solvents commonly used in paints
  • Polymer content biodegradable

Dosage

  • Typical addition range: 5%–9%
  • The required dosage level highly depends on the system (e.g. binder type, additives, solvent content) and ap- plication parameters such as layer thickness and film shrinkage. Thus, it is highly recommended to determine the needed addition level by a practical ladder study.

Processing

  • The PMU chemistry in general is highly compatible in a wide range of systems. Due to that Deuteron® MM matting 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.
