Bermocoll E 451 FQ

About this product

Bermocoll® E 451 FQ is a non-ionic, water-soluble cellulose ether. It improves the consistency, the stability, and the water retention of water-based products.

Brand: Bermocoll® Chemical family: Cellulose ether

Applications: 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.

In opened bags, the moisture content of Bermocoll® E 451 FQ will be influenced by the air humidity. At the temperatures above 250 C (480 F), charring of Bermocoll® E 451 FQ will occur. Packaging and transport: Like many industrial powdery materials, cellulose ether dusts are combustible and can cause dust explosions. Dust formation must be avoided or kept to a minimum. Care should be taken to prevent ignition from heat, spark, open flames or hot surface. Bermocoll® E 451 FQ is packed in a polyethylene bag. Net weight 20 kg. We recommend emptying the bags from the bottom. In unopened bags, Bermocoll® E 451 FQ can be stored for several years. In opened bags, the moisture content of Bermocoll® E 451 FQ will be influenced by the air humidity.At the temperatures above 250 C (480 F), charring of Bermocoll® E 451 FQ will occur. At high temperatures and in contact with an open flame, Bermocoll® E 451 FQ will burn slowly with the characteristics of cellulose. Safety and handling: At high temperatures and in contact with an open flame, Bermocoll® E 451 FQ will burn slowly with the characteristics of cellulose.
