• We developed the unique method of creating spherical fine particles, called SB series.
  SB series are made from many kinds of waxes and have been selling this products.
• The SB series are micronized spherical particles (d50: under 1 µm ～ above 10 µm).
  We produce its powder to disperse as hard paste and liquids.
  SB series dispersion are available to use for many kinds of Printing Inks, and Paints as a additives. Also, the product can be added to the ink vehicle to make a paste.
• The SB series are available to use for various purposes.

Characteristic:

• Particles remain chemically stable and non reactive.
• Particle size distribution can be controlled.
• Melting point： ca. 80 to 200 degree C.
• Optional: surface treatment (Hydrophilic/Hydrophobic, Fluidization)

1.Particle size distribution of SB series

SB series are micronized spherical particle (d50: under 1 µm - above 10 µm).

• Comparison of rub resistance performance of SB-25 and PTFE particles (heat set printing ink)

Test Method:
Paper	Pearl coated paper
R.I. Tester	2 divided rolls
Ink volume	0.125 cc
Colorfastness Rubbing Tester (Gakushin Tester)	500 g x 10 times

1 weight percent (wt%) PTFE 1 : Ink 100

1 wt%

※To use SB-25 (1 wt%) properly, the Rub-resistance performance will be improved as compared with PTFE (1 wt%).

• SB-60 Evaluation of off-set prevention performance (normal temperature dry type offset sheet-fed ink)

Test Method:
Paper	Special art paper
R.I. Tester	2 divided rolls
Ink volume	0.15cc
Weight	500 g / cm 2

※Starch: organic material/anti blocking powder for prints.

※Anti blocking effect of SB-60 performs better than starch.

• Spherical fine particles (SB series) is can be used all kind of field.
• Developing in various fields.
