1 Dispersing Agent AJINOMOTO FINE-TECHNO CO., INC.

2 AFT Dispersing Agent: AJISPER & PLENACT Improves Dispersibility of Fillers or Pigments in Plastics or Solvents Applications:Paints, coatings,inks, High quality Inkjet ink, Plastic masterbatchs, and LCD colorfilter etc. Polymer dispersing agent: Mainly improves dispersibility of organic pigments Alminate Coupling agent: Mainly improves dispersibility of inorganic fillers and carbonblack.

POLIMER TYPE DISPERSING AGENT AJISPER are novel pigment dispersing agents offering the following advantages to products now available on the market. 1.

4. Excellent stability in mixed pigment systems PB-821 : Basic type, pale yellow flakes, suitable for (PB-822) organic pigments and carbon black.

3 POLIMER TYPE DISPERSING AGENT AJISPER are novel pigment dispersing agents offering the following advantages to products now available on the market. 1. Usable in a broad range of resins 2. Facilitates dispersion even in highly viscous formulation. 3. Permits considerable reduction in dispersion times. 4. Excellent stability in mixed pigment systems PB-821 : Basic type, pale yellow flakes, suitable for (PB-822) organic pigments and carbon black. PN-411 : Neutral type, pale brown liquid, suitable for organic and inorganic pigments PA-111 : Acid type, pale yellow liquid, suitable for inorganic pigments

Tokyo, Japan. PLEN-ACT AL-M reacts with the surface of inorganic fillers and forms an organic film on the surface. Inorganic fillers treated with AL-M exhibit good compatibility with various resins and plastics. Paints containing AL-M treated carbon black have more jetness since more light is absorbed due to particle deagglomeration and the resultant reduced reflection gives the effect of greater blackness to the human observer.
