Special Features and Benefits

The additive deflocculates pigments by means of steric stabilization. As a result of the small particle sizes of the deflocculated pigments, high levels of gloss can be achieved and the color strength is improved. Transparency and hiding powder also increase and viscosity is reduced. In this way, the flow characteristics are also improved and higher pigment loading is possible.
Recommended Use
The additive is recommended for all aqueous, solvent-borne and solvent-free systems to stabilize inorganic pigments, specifically titanium dioxide.
Recommended Levels
Amount of additve (as supplied) based upon pigment.
Inorganic pigments: 5-10%
Titanium dioxide: 1.5-2.5%
The above recommended levels can be used for orientation. Optimal levels are determined through a series of laboratory tests.
Incorporation and Processing Instructions
For optimum performance, the additive must be incorporated into the millbase before addition of pigments. The resin and solvent components of the millbase are pre-mixed and then the additive is slowly incorporated while stirring continuously. Do not add the pigments until the additive has been fully distributed.
