Flowtone ST Castor wax Cray Valley Rheology Modifier/ Thickener >> Organowax >> Castor Oil derivative (HCO-wax) Coatings >> Solventborne Coatings >> Solvent-Free/ High-Solids General Industrial /Maintenance Flowtone ST Flowtone ST is a 100% active amide modified castor wax for the control of sedimentation and sag resistance in solvent-based coatings. Flowtone ST is suited to coating systems based on aliphatic hydrocarbons, aromatic hydrocarbons and aromatic hydrocarbon/alcohol blends. Compared to the most basic castor wax rheology modifiers, Flowtone ST is more tolerant to stronger solvents. The result of this is a lowered risk of problems such as seeding and false-body. Flowtone ST is also suitable for use in solvent-free systems. 100% active amide modified castor wax. Used for solvent-based and solvent-free coatings. Used for coating systems based on aliphatic hydrocarbons, aromatic hydrocarbons and aromatic hydrocarbon/alcohol blends. Imparts shear-thinning rheology with thixotropic viscosity recovery. Gives very good anti-settle properties and recoatability. Tolerates stronger solvents.
