Deuteron® MM 684

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.

Deuteron®® MM 684 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: 1%–8%
• 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.

• Paper bag (10 kg net)

• 24 months at room temperature and dry conditions.
• Storage temperature should not exceed 35°C.
