  • Applications

    BERMOCOLL EHM Extra can be used as a thickener in all types of latex paints, both in interior and exterior formulations. BERMOCOLL EHM Extra improves high shear viscosity, roller spatter, flow and leveling. BERMOCOLL EHM Extra offers enhanced color and heat stability, good color acceptance with minimal flocculation even when the most problematic colorants are used. Normal dosage is 0.1 to 0.8%, calculated on the total paint weight. In order to facilitate dispersion in water, BERMOCOLL EHM Extra has been treated to give a pH-dependent dissolving.It should be added to neutral or slightly acid water. To speed up the dissolving process, pH should be increased to above 8 by using alkaline ingredients such as ammonia or alkaline pigment dispersants.If adjustment of the final paint viscosity is necessary, a highly concentrated slurry either in water or in an organic solvent should be used. It is not recommended to add the product as a dry powder after pigment grinding, due to the risk of lump formation at alkaline conditions.
