ProductApplications
Bermocoll® E 451 FQ is used in latex paints for thickening and stabilizing effects. Normal dosage in paints is 0.2 -0.5 % calculated on total paint weight. Bermocoll® E 451 FQ is used in cement-based tile fix and joint mortars for improvement of workability, consistence, water retention, and adhesion.Normal dosage in mortars is 0.3 - 0.6 % calculated on dry mortar weight. Bermocoll® E 451 FQ is easily dispersed in cold water of pH 7 or less. Bermocoll® E 451 FQ can form lumps when added to alkaline liquid. To avoid this, it should be added as a ready stock solution, as a slurry in slightly acid water or in 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.
