Bermocoll EHM Extra A (Methyl ethyl hydroxyethyl cellulose)

About this product

Bermocoll® EHM Extra A is an associative non-ionic, water-soluble cellulose ether that improves the rheological properties of water based paints.

Brand: Bermocoll® Chemical family: Cellulose ether Regional availability: Global Chemical name: Methyl ethyl hydroxyethyl cellulose

Applications: Bermocoll® EHM Extra A can be used as a thickener in all types of latex paints, both in interior and exterior formulations. Bermocoll® EHM Extra A improves high shear viscosity, roller spatter, flow and leveling. Bermocoll® EHM Extra A 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 A 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.
