Processing Instructions

RHEOBYK-7590 should be added to the oil phase or at the beginning of the dispersion process, preferably by pre-mixing 5 – 10 minutes with the solvent or oil.

For optimal performance, this product should be fully activated by heating the batch to a temperature between 45°C and 65°C and applying high shear mixing for 20 minutes while maintaining the temperature. Within this range, the appropriate temperature to activate this product depends on the solvent used – less polar solvents need a higher temperature for the activation.

RHEOBYK-7590 is sensitive to temperature. Seeding (building of soft gel-like particles) may occur if the activation temperature is not high enough or if the maximum activation temperature of 65°C is exceeded. If this happens, the lot may be reworked by bringing the batch to an activation temperature (55 – 65°C) and applying intensive high shear.
