About This Product

BYK's rheology agents provide improved processability and excellent storage stability, and some products also have the ability to adjust film thickness. Rheology additives can significantly improve performance in a wide range of applications. However, individual solutions and optimal formulations of rheological properties are required to achieve the required performance. For example, increasing storage stability requires different viscosity performance rather than increasing layer thickness. Viscosity at low shear requires a different approach than increasing contact resistance. Furthermore, it is essential to select the optimal additive depending on the polarity, such as solvent, non-solvent, or water-based. BYK offers a wide range of additives that can be applied to a variety of systems and polarities. These include layered type, associative thickener, and high-performance additives such as synthetic hectorite. It is characterized by high compatibility and transparency. Liquid rheology agents are easy to add. Product data

■Composition

Nonionic emulsion of modified ethylene vinyl acetate copolymer wax (EVA)

■General properties

The values ​​listed in this data sheet are representative values ​​and are not quality standards.

■Food contact applications

Please contact us for the latest legal compliance status for food contact applications.

■Storage and transportation

It is sensitive to temperature and should be stored and transported at temperatures between 5°C and 35°C.

■Application field

paint

■Features

This rheology additive improves the orientation of effect pigments and reduces unevenness. At the same time, the sedimentation of the paint during storage and processing is reduced. This additive is less sensitive to co-solvents than urethane thickeners and is much easier to add and handle (ready to use) than clay and acrylic thickeners. AQUATIX 8421 is highly effective in improving the rheological properties and brightness of effect pigment slurries without co-solvents.

■Recommended use

・Automotive paint ・Industrial paint

■Recommended addition amount

5-10% as an additive to the total formulation. Please use the recommended addition amount as an initial value. Please conduct an actual test to determine the optimum amount to add.
