Bermocoll® Prime 2530 can be used as a rheology modifier in all types of latex paints. Bermocoll® Prime 2530 is recommended when high in-can as well as enhanced application viscosity is required. Bermocoll® Prime 2530 offers enhanced colour and heat stability, and provides excellent colour acceptance even with colorants that are known to be problematic. Normal dosage is 0.2 - 0.7 % calculated on the total paint weight.Bermocoll® Prime 2530 is easily dispersed in cold water of pH 7 or less. Bermocoll® Prime 2530 can form lumps when added to an alkaline liquid. To avoid this, it should be added as a ready stock solution, as slurry in slight acid water or in an organic solvent, or as a dry mix with other powder materials.The dissolving time after dispersion is influenced by the water pH. Alkaline additives can be used to speed up the dissolving process.
