Special Features and Benefits
After being stirred into the coating system, the additive generates a three-dimensional network structure. The resulting thixotropic flow behavior is highly suited for preventing sedimentation and increasing the anti- sagging properties without impairing leveling. As a result of associative interaction of RHEOBYK-411 with the used binder, the rheological effect is also significantly dependent upon the type and quantity of the binder.Recommended Use
The additive is recommended for low-polarity systems. RHEOBYK-410 is better suited for medium-polarity systems. We recommend RHEOBYK-420 for high-polarity and aqueous systems.Recommended Levels
0.2-1% additive (as supplied) based on the total formulation to prevent settling. 0.5-2% additive (as supplied) based on the total formulation to prevent sagging.
The above recommended levels can be used for orientation. Optimal levels are determined through a series of laboratory tests.Incorporation and Processing Instructions
The additive should be added to the coating whilst stirring using moderate shear forces to ensure a rapid, homogeneous distribution. It is not necessary to specifically control the temperature. The additive can be added to the millbase and is also suitable for adjusting the viscosity afterwards by incorporating it as a post-additive.Special Note
If used with driers (siccatives), discoloration may occur due to the formation of metal complexes. The rheological effectiveness should then be tested.

Storage & Handling
- Storage and Transportation
Moisture sensitive. Store dry. Slight turbidity of the material that occurs during storage has no influence on the rheological effectiveness. The specified storage stability upon dispatch applies when the product is handled correctly and stored in unopened original containers.
