| Solution of a phosphoric ester salt of a High molecular weight copolymer with pigment affinic groups |
 |
Disperbyk-142 deflocculates pigments through steric stabilization of the pigments.
It provides electrical charge to pigments and thus avoids possible co-flocculation of pigments that are not equally charged.
Due to the small particle sizes of the deflocculated pigments, high gloss isd achieved and color strength improved.
Additionally, transparency and hiding power are increased.
The additive reduces viscosity, subsequently, levelling is improved and higher pigment loading is possible.
Disperbyk-142 displays excellent compatibility with all common paint binders.
As a special note, for nitrocellulose and thermoplastic acrylics (TPA), Disperbk-142 displays superb compatibility.
Before usage in white baking enamels, Disperbyk-142 should be checked for possible yellowing influence .
If yellowing occurs, Disperbyk-180 is recommended to stabilize titanium dioxide. |
