COADIS 123K is a synthetic, versatile dispersant that provides easy fillers and pigments dispersion, good storage stability, and improved water resistance to water-borne systems. It is recommended for flat or gloss dispersion paints, renderings and plasters, and also organic pigment pastes (e.g. carbon black dispersion). Its utilization contributes to avoiding flotation and foam generation and provides excellent color acceptance.
With its hydrophobic character, Coadis 123K significantly contributes to improving the water resistance of water-based systems with high PVC, such as plasters, renderings, and flat dispersion paints, compared with classical acrylic dispersants. Water resistance can be estimated, e.g. for flat dispersion paints, through wet scrub resistance tests on dry film or early water resistance tests on recent film.
Replacement of a classical acrylic dispersant by Coadis 123K in a washable flat dispersion paint can raise the water resistance of the paint up to a scrub resistance level.
Coadis 123K requires levels of use between 0.1% and 1% (dry product on total formulation weight) and more often between 0.1% and 0.5% (e.g. in renderings, in flat and gloss dispersion paints). Levels of use are higher for the formulation of organic pigment pastes and can reach until 15% for a carbon black dispersion (dry product on pigment weight).
This product should be added preferably before pigment introduction in order to reach the best dispersing efficiency, but can also be introduced at each step of the formulation if needed.
