Aqueous dispersant RK-165A

RK-165A Modified polycarboxylic acid copolymer ammonium salt dispersant

Product Overview

HR-165A is a hydrophobic modified polycarboxylic acid copolymer ammonium salt with ABA structure. The main chain of the molecule has both hydrophobic olefin groups and carboxylic acid groups with regular ABA structure, which makes the molecule take into account both hydrophobicity and dispersibility at the same time, and it is a kind of weathering and dispersing additive with excellent performance. This polymer can effectively improve the water resistance and stain resistance of the paint film, and at the same time, it can play an effective role in the dispersion of non-polar pigment fillers, which can effectively reduce the amount of polyoxymethylene-modified dispersing agents and save the cost of formulations.

Characteristics

◆ It is suitable for water-based system, and can be used for grinding resin-free water-based color paste.

◆ It belongs to polymer-type hyperdispersant with excellent wettability, and it has excellent ability of preventing the return of coarseness compared with small molecule-type wetting and dispersing agent. Application Suggested dosage Recommended for aqueous systems. The dosage is different according to different systems, 0.1~0.5kg per 100L of paint, and the optimized dosage should be determined according to the demand of pigment and filler addition and dispersion. Inorganic pigment, 1%-5%, organic pigment 20%-50%, carbon black 30%-100%, titanium dioxide 10% Packing, transportation and storage 25kg iron drum/plastic drum.

Sealed storage, 12 months at room temperature.
