Deuteron® PMH C

• Deuteron® PMH C is a micronized duromeric plastic powder based on PMU (Polymethyl urea). The unique synthesis of Deuteron® PMH C leads to a well-balanced mix between compact and amorphous particle structures – this property makes it a good matting agent with very low influence on viscosity and porosity. Because of their highly compatible chemistry Deuteron® PMH C can be used as matting agent in a wide variety of different applications and systems.
• Compared to the Deuteron® MK family our Deuteron® PMH C shows less matting efficiency but significantly less influence on viscosity and improved flexibility.

Deuteron® PMH C can be used in almost all coating appli- cations ranging from water borne and solvent borne to 100 % systems. It can be used as stand-alone additive or in combination with other materials to further improve their properties.

The use of Deuteron® PMH C especially improves the following properties:

• Good matting effect
• 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

Dosage

• 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.

Processing

• The PMU chemistry in general is highly compatible in a wide range of systems. Due to that Deuteron® PMH C 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 processes but should not be ground in a bead mill.

• Paper bag (15 kg net)

• 24 months at room temperature and dry conditions.
