Omya - BYK-P 104 - Carboxylic Acids & Derivatives

Coatings Industry
Special Features and Benefits
BYK-P 104 provides a targeted, controlled flocculation of the pigments. Bridges are built between the individual pigment particles, thereby creating three-dimensional networks. This controlled flocculation of the pigments primarily prevents flooding and floating along with settling and sagging. BYK-P 104 is particularly suited to medium-polarity to high-polarity coating systems to prevent the flooding and floating of titanium dioxide in combination with colored pigments. It has a limited compatibility with white spirit. In many cases, anticorrosive properties are improved when used in protective primers.

Recommended Levels
Amount of additive (as supplied) based upon pigment:

Inorganic pigments: 3-10%
Titanium dioxides: 0.5-2.5%
Organic pigments: 10-20%

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.
