Rheology Modifier (solvent‑based) Suitable for Industrial, Architectural and Automotive Coatings
ADDEX‑R 4619 is a solid rheological additive for solvent‑based and solvent‑free systems, providing strong thixotropy and significantly increasing viscosity in coatings. It is particularly recommended for coating systems that undergo high‑temperature manufacturing processes.
ADDEX‑R 4619 is compatible with a wide range of solvent‑based resins and ensures consistent performance in improving anti‑sagging properties and controlling pigment settling.
Key Applications and Main Features
ADDEX‑R 4619 is used in both solvent‑based and solvent‑free coating systems, with the following key characteristics:
- Compatible with all major resin types, including alkyd, polyester, epoxy, polyurethane, and nitrocellulose
- Enhances and stabilizes thixotropic behavior
- Improves viscosity, anti‑sagging performance, and rheological stability
- Functionally equivalent to EFKA RM 1900
- Contributes to better leveling and supports air release within the formulation
