Deuteron SF 505

• Deuteron SF 505 and SF 707 are thermosetting additives primarily composed of polymethylurea resin powder. These additives enhance the smoothness and provide a pleasant grip to surfaces. They are particularly effective in reducing the coefficient of friction and increasing scratch and abrasion resistance. Notably, they contain no waxes or silicones.

  Here are some key properties and characteristics of Deuteron SF 505 and SF 707:

  • Bulk density: Approximately 450 g/l for SF 505 and 430 g/l for SF 707.
  • Specific weight: Approximately 1.4 μm for both additives.
  • Particle size:
    • d50 (median particle size): Approximately 7.0 μm for SF 505 and 4.0 μm for SF 707.
    • d90 (90th percentile particle size): Approximately 13.0 μm for SF 505 and 8.0 μm for SF 707.
    • d99 (99th percentile particle size): Approximately 18.0 μm for SF 505 and 12.0 μm for SF 707.
  • Appearance: Both additives appear as fine white powders.

  These additives are designed to provide surface modification, offering smoothness and a pleasant tactile sensation. They can significantly reduce friction and enhance scratch and abrasion resistance. Importantly, they are compatible with various systems and can be mixed with other powders, such as PMU powders, SiO2 powders, waxes, and other fillers.

  Dosage recommendations for Deuteron SF 505 and SF 707 vary depending on the desired surface effect, typically ranging from 0.5% to 4.0%. The optimal dosage for specific formulations should be determined through trials.

  In terms of processing, these additives can be easily incorporated into lacquers using a stirrer or dissolver. They do not require the use of surfactants, even in aqueous systems, and exhibit relatively high resistance against shear forces.

  Deuteron SF products can be stored for at least 24 months under room temperature and dry conditions. While they are not classified as dangerous products according to Regulation (EC) No. 1272/2008, precautions should be taken to avoid dust exposure and electrostatic charge buildup.

  Overall, Deuteron SF 505 and SF 707 are versatile surface additives suitable for various applications where smoothness, tactile sensation, and improved mechanical resistance are desired.
