Flocculating agents are available as liquids, powders, or dispersible solids. Their key benefits include optimized viscosity, enhanced color development, and improved storage stability. In coatings, flocculating agents are particularly useful in pigment dispersions, ensuring uniform application, better opacity, and controlled rheology in architectural, industrial, and protective coatings.
A growing trend in the coatings industry is the adoption of bio-based and low-VOC flocculants. Sub-types include ionic and nonionic flocculating agents.

Dytek® BHMT-HP (Bis(hexamethylene)triamine) by Invista acts as an emulsifier, curing, flocculating and chelating agent. It is highly pure, solid aliphatic triamine that provides unique properties when used in a variety of amine applications including polyamides and epoxies. It is a polyurethane extender or catalyst. Dytek® BHMT-HP (Bis(hexamethylene)triamine) is suitable for inks applications.
CLiQSPERSE® CG by CLiQ SwissTech acts as a controlled flocculant, wetting agent for non-aqueous coatings, inks and also acts synergistically with organically modified smectite clays to improve sag resistance of coating systems. It is electroneutral salt of a polycarboxylic acid. It exhibits strong reduction in pigment floating and flooding in paints and inks, improves anti-settling behavior and storage stability of solvent-borne systems. Provides excellent de-lamination of the organoclay already at moderate activation shear forces. CLiQSPERSE® CG is recommended for non-polar and mid-polar systems to improve wetting of all kind of pigments or extenders and as an activator for organoclays to produce stable, low viscous and pump-able non-aqueous pre-gels.
Copper phthalocyanine blue beta form. It shows an excellent solvent stablilty with extremely good resistance and flocculating resistance in most solvent based applications. It imparts high gloss strength and free flowing characteristics. It has many industrial applications in paints and coating for e.g. air drying enamel, powder coating, emulsion paints, auto finishes. Also in printing inks like special gravure and flexographic inks.
