Special Features and Benefits
RHEOBYK-7594 improves the anti-sagging and anti-settling behavior of the coating, without influencing the in-can viscosity. Combinations with wetting and dispersing additives which have a controlled flocculating effect are particularly recommended.
RHEOBYK-7594 is exceptionally suitable for low-viscosity systems such as glazes and for alkyd resin systems, but is also broadly compatible with most coating systems.

Recommended Levels
0.7% additive (as supplied) based on the total formulation.
The above recommended levels can be used for orientation. Optimal levels are determined through a series of laboratory tests.

Incorporation and Processing Instructions
RHEOBYK-7594 is easy to incorporate and can be added to the formulation at any time, but is particularly suitable for post-addition. No temperature activation is required.
