AgeSin® RH-A4425 is a liquid rheological additive designed for waterborne systems. It builds a reversible rheological network through intermolecular hydrogen bonding, precisely regulating in-can viscosity, providing long-term anti-settling performance, and significantly improving anti-sagging properties. Its rheological performance is not affected by pH, and it does not compromise gloss or transparency. Suitable for a wide range of waterborne coating formulations.
