First, Introduction
Dispersant LD-1028 can adsorb on the surface of carbon black effectively to improve carbon black’s wetting dipersity
and shorten grinding time.Meanwhile, it can improve the film’s blackness gloss. There is no phenomenon of viscosity increase
on standing. And it can avoid the effect of floating and flooding. LD-1028 can be used as grinding color-expanded agent of carbon black by adding it into coating.
Second, Components
Polymer containing special group
Third, Performance
Appearance: Light brown viscous liquid
Organic contents: 100%
PH: 4-5
Relative Density: 0.914-1.140g/cm³
Fourth, Application Scope
In alkyd、nitro、acrylic acid、Chlorinated Rubber and PU、PE coatings, it is appropriate for solvent type industrial paint and
oiliness ink.
In mixed solvent, the adsorbing capacity to pigment and filler is better than similar additives.
It is appropriate for heterogeneity of carbon black adsorption.
This product has good wetting and dispersing effect for all kinds of pigments, no floating and flooding phenomenon
in multicolor paint. Also it can improve the adhesive force to coatings and inks, brighten the color and enhance the storage stability.
Fifth, Usage and Consumption
For black paint, the consumption is 6%-12% of carbon black, after diluting with xylene, then add it before grinding.
For black paste, the consumption is 10-15% of the total amount, firstly diluted with low concentration resin liquid, then grinded together with carbon black.
For solvent type coating and ink, the consumption is 0.5-1.0% of total amount of formulation. Adding the dispersant into painting directly, after mixed well, add pigment or filler for
grinding(other agents should be added after pigment、filler dispersed for several minutes).
