DAHSPERSE N-2618 is a high molecular weight organic acid surfactant, especially for pigment dispersion . DAHSPERSE N-2618 can be quickly and effectively disperse the pigment in water while reducing the pigment slurry sludge (SLURRY) of viscosity. Further , it can be made of other high concentration pigment dispersing agent can not be achieved glue suspension .

[ Long ] special
1, DAHSPERSE N-2618 can improve various inorganic pigments such as : SATIN-WHITE, ZnO, CaCO3, AI (OH) 3 ( aluminum hydroxide ) TiO2 ( titanium dioxide ) , clay , talc, etc. The dispersion effect in addition, it can significantly reduce the viscosity of the slurry of mud .
2, with DAHSPERSE N-2618 as a pigment dispersant , because good thermal stability , so the storage process , even if the temperature increased by dispersion , it does not produce increased viscosity problems.
3 , a coated paper, particularly as the use of starch -based BINDER ( binder) of the coating , the storage time by increasing the viscosity of the coating is not a dispersant .
[ Usage and Performance ]
1 paper coating pigment dispersing agent:
Usually a pigment dispersing agent used as : Sodium hexametaphosphate, Sodium tripolyphosphate and other inorganic phosphate has the following disadvantages:
(A) the pigment is not sufficiently reduced mud slurry (slurry) of viscosity
(B) has the disadvantage of changes over time , i.e., after a long time , increases the viscosity of the dispersion ; DAHSPERSE N-2618 is excellent in removing the drawbacks of the product , it may be mixed with water in any ratio . In the paper coating pigment as a dispersing agent, particularly suitable for the starch / emulsion based coating , can play a very excellent effect .
Currently , in the coating industry , in order to save costs and is committed to large-scale coating machine , high speed. In response to these needs, the low viscosity of the coating and a high concentration of color is very necessary. DAHSPERSE N-2618 I can meet the above requirements .
Use DAHSPERSE N-2618 has the following advantages :
⊙ DAHSPERSE N-2618 to make an inorganic pigment such as : Sarin white, ZnO, CaCO3, Al (OH) 3, TiQ2, clay, talc and the like dispersed in a very stable , especially when the inorganic phosphate can not be effectively dispersed Satin-White, DAHSPERSE N-2618 in particular, can play a good effect.
⊙ DAHSPERSE N-2618 without mixer (mixer) can also be modulated high concentrations of paint. However, to obtain the desired coating , preferably a high concentration of paint mixer modulation more appropriate .
⊙ DAHSPERSE N-2618 due to the viscosity of paint can be stable , and therefore the use of high-speed blade coating , no problems.
⊙ starch / ( latex ) paint during storage LATEX, when the temperature is higher than 25 ℃, adding dispersant DAHSPERSE N-2618 prevents viscosity increase .
⊙ used when dispersing paper coatings, the viscosity does not increase due to the length of storage time DAHSPERSE N-2618.
(2) water-soluble paint , EMULSION paint :
A) DAHSPERSE N-2618 can be used in a variety of inorganic pigments and organic pigments.
B) DAHSPERSE N-2618 was strongly adsorbed on the surface of the pigment , the pigment surface with a negative charge , it becomes easy to disperse .
C) When the pigment is difficult to disperse in case of other dispersants , DAHSPERSE N-2618 can also be stably dispersed .
When D) Emulsion paints and coatings using water amounts used DAHSPERSE N-2618 is 0.3% (OWP).
(3) Other:
A) Ceramic dispersant
B) wettable powder pesticide dispersant
4 Packing: NW 250KG plastic drum
※ Under normal conditions of use , DAHSPERSE N-2618 will not hurt the skin ; However, users at the end of the work , it is best to wash your face and hands thoroughly with soap . |
