Application: TEGO® RHEO 8600 is a very efficient thickener for dispersions based on acrylates, vinyl-ethylene-copolymers (VAE) and polyvinyl acetate (PVAc). TEGO® RHEO 8600 provides high viscosity in dispersions where standard thickening agents such as acrylates at low pH or polyvinyl alcohols for PVAc/VAE-dispersions fail. Its Newtonian flow behavior is beneficial in applications wherein thick layers need to be applied such as in construction tapes. Additionally, TEGO® RHEO 8600 is very useful, if the adhesive needs to be applied very precisely e. g. in dots without flowing apart. Such applications require a high viscosity that can stand high shear stress.

Properties / Benefits: TEGO® RHEO 8600:

• is used as thickening agent for water-based systems
• provides good long term stability
• shows Newtonian flow behavior
• is highly efficient even at lower pH-values
• improves leveling
• can be combined with other thickeners
• is solvent free
• does not contain emulsifiers
