Bermocoll® EHM 100 ED

Associative non-ionic, cellulose ether that improves the rheological properties of water based paints. Hydrophobically modified ethyl hydroxy ethyl cellulose. Opaque solution appearance. Can be used as a thickener in all types of latex paints, intended for interior as well as for exterior use. Improves high shear viscosity, roller spatter, flow and levelling. High resistance to enzymatic degradation. Normal dosage is 0.3 - 0.5 % calculated on the total paint weight. Has been treated to give a pH-dependent dissolving, in order to facilitate dispersion in water. 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. Under the alkaline pH conditions at that stage it will dissolve too rapidly with the risk of lump formation.
