RHEOBYK-425

RHEOBYK 425 is a VOC-free rheology additive that can be used to set the in-can viscosity and improve anti-sagging and anti-settling properties of aqueous systems. As a liquid urea-modified polyurethane solution, RHEOBYK 425 associates with dispersion particles to provide highly pseudoplastic flow behavior. Its rheological effectiveness is based on associative interactions and is not dependent on pH. RHEOBYK 425 can be easily incorporated and processed without negatively impacting properties. For advanced material formulations requiring precise viscosity control and stability, RHEOBYK 425 is a suitable additive to maintain uniform dispersion of particles and prevent settling without affecting optical properties. The pseudoplastic nature of RHEOBYK 425 allows optimized handling and application of advanced material dispersions and coatings.
