nature

(This data is only for test reference. If you need detailed product inspection technical indicators, please contact our company.)

Composition: electrically neutral polycarboxylate amine salt

Appearance: brown slightly turbid liquid

Non-volatile: 48-52%

Solvent: aromatic hydrocarbon solvent

Specific gravity: about 0.89

Refractive index: 1.488-1.498 (25 ℃)

Characteristics and use

Suitable as a wetting and dispersing agent for various inorganic pigments in solvent-based coatings

With special interfacial activity, it can help the wetting and deflocculation of the pigment. Therefore, it can greatly shorten the dispersion time, adsorb on the surface of the pigment to prevent back coarsening, and make the paint have good storage stability

It is a good activator for bentonite. Add The bentonite pre gel of VOK®-Disponer 923 has the following advantages: shortening the dispersion time; Adjustable viscosity, easy to operate; Improve anti-settling and sagging; Improve storage stability

application area 

Alkyd/amine resin

Ready-mixed paint

Epoxy coating

Acid curing

Chlorinated rubber

Addition amount and use method

As dispersant: add 0.5-2.0% of the total amount of pigment

As bentonite activator: add 30-50% to bentonite

Good results can be obtained by adding before grinding
