2. Overview:


         This product is a composite monoalkoxy titanate, which has the dispersibility of phosphate ester and the coupling of titanate ester, and has excellent surface activity. And it has a wide range of applications. It can be used in plastics and rubbers to activate various pigments and fillers. It is an excellent surfactant for pigments, with remarkable dispersing effect, especially effective for carbon black dispersing characteristics. It is the best special additive for concentrated color masterbatches.

4. Scope of application:


        Concentrated color masterbatch (polyolefin system); general inorganic and organic pigments; coatings, rubbers and inks, etc.

        Widely used in the surface treatment of organic and inorganic pigments.

        It is used in the manufacture of plastic concentrated color masterbatches to improve the dispersibility of pigments, so that the products have high coloring degree, uniformity, bright color and good gloss. In particular, it can increase the filling amount of carbon black by 10%-15%, and significantly reduce the cost of black masterbatches .

        After application in the coating industry, it can improve the dispersibility of the pigment, so that the coating does not crust or precipitate, and can also improve the heat resistance of the pigment and reduce the baking temperature of the baking paint.

        Mixing with other coupling agents in the ink industry can improve the dispersibility of the pigment, so that the ink does not smear or precipitate, the pigment is dispersed evenly, and the adhesion is high.


5. Features:


       1. High-speed stirring and dispersing without external heating;

       2. Increase the filling amount of the pigment, and the color of the product will be thicker;

       3. The dispersibility is improved, the processing is convenient, and the work efficiency is improved;

       4. The products are bright in color, bright and resistant to aging;

       5. Anti-flickering, anti-sinking and improving adhesion in coatings and inks.


6. Dosage:


       It is 0.5-2.0% of the total amount of pigments or fillers, the recommended dosage is 1.0%, and the maximum usage amount should be determined experimentally.


7. Usage:


       Put the filler or pigment to be treated in the high-speed mixer, slowly add the product diluted with 1:1 diluent under the condition of low-speed rotation of the mixer, and then start the high-speed stirring for about 5-15 minutes, Add resin and other auxiliaries according to the original process. If it is added during grinding, it can also be added (different grinding machines have different effects), but the dispersion effect is worse than the above-mentioned pretreatment method.


Solvent selection


       Plastic industry - liquid paraffin (ie white oil); rubber industry - 200# solvent or motor oil; paint industry - 200# solvent or isopropyl alcohol.


Eight, matters needing attention:


      After high-speed processing, the pigment should pay attention to heat dissipation if it is discharged for use.

      Valid for one year (from the date of manufacture).
