Deuteron® SF 707

• Deuteron® SF 707 is micronized duromeric plastic powders based on PMU (Polymethyl urea). The unique synthesis of Deuteron® SF surface additives leads to compact particle structures with high hardness and low COF (coefficient of friction) – this property makes them excellent alternatives to traditional PTFE based additives.
• Because of their highly compatible chemistry they can be used in a wide variety of different applications and systems.
• Deuteron® SF products can be used as 1:1 offset to replace PTFE based surface protection additives and waxes.

Deuteron® SF 707can be used in almost all coating applications ranging from water borne and solvent borne to 100 % systems. This can be used as stand-alone additives or in combination with other materials to further improve their properties.

Deuteron® SF 707 is suitable for thin and thick film applications. The use of Deuteron® SF additives especially improves the following properties:

• Reduced COF (coefficient of friction)
• Scratch and polishing resistance
• Low impact on the gloss level at low dosages
• Pleasant surface feel
• Excellent recoatability
• Temperature resistant up to over 200 °C, short-time up to over 300 °C
• Mimic wax effects without negative influence of waxes
• Less haze and settling compared to PTFE
• Biodegradable polymer 

Dosage

• Typical addition range: 0.5 % - 4.0 %
• The required dosage level highly depends on the system (e.g. binder type, additives, solvent content, etc.) and application 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® SF addi- tives can be incorporated easily by a high-speed stirrer without the need for specific wetting agents or dispers- ing aids. They are shear stable in high shear processes but should not be ground in a bead mill.

• Paper bag (25 kg net)

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