Flocculating Agents for Coatings and Inks

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.

AERODISP® W 7520 P by Evonik is an adhesion promoter, rheology control, flocculation aid and anti-slip agent. It is a low-viscosity, water-based dispersion of fumed silica with slightly alkaline pH. It offers emulsion stabilization, low thickening effect and surface treatment such as polishing. AERODISP® W 7520 P is used in printing inks.

Formulation of modified urea. Reduces the drying and caking of pigment concentrates. Controls the evaporation of water very effectively to prevent aqueous concentrates from drying and caking. Used in universal pigment concentrates and aqueous pigment concentrates.

Armac® T by Nouryon functions as a mineral and pigment, dispersing agent and emulsifier, floculant, adjuvant and anticaking agent. It is a primary tallow amine acetate salt. Armac® T is suitable for inks and pigments applications.

KEPERDISP® -605 by Kito Chemical is a hydroxy unsaturated fatty ammonium salt. It acts as a flocculating and dispersing agent. It can be diluted in water/isobutanol. It reduces sagging tendency in high filler content system. It prevents pigment settling and stabilize pigment. KEPERDISP® -605 is suitable for water-based coatings neutralized by amine and small thixotropic resins. Recommended usage level is 1-5% for inorganic pigment and 0.5-1% for titanium dioxide and filler.
