Bermocoll Prime 2500 (Methyl ethyl hydroxyethyl cellulose)

About this product

Bermocoll® Prime 2500 is a non-ionic, water soluble cellulose ether with enhanced enzymatic resistance, and superior colour stability. It improves the consistency, the stability, and the water retention of water based paints.

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

Applications: Bermocoll® Prime 2500 can be used as a rheology modifier in all types of latex paints. Bermocoll® Prime 2500 is recommended when high in-can as well as enhanced application viscosity is required. Bermocoll® Prime 2500 offers enhanced colour and heat stability, and provides excellent colour acceptance even with colorants that are known to be problematic. Normal dosage is 0.2 - 0.7 % calculated on the total paint weight.Bermocoll® Prime 2500 is easily dispersed in cold water of pH 7 or less. Bermocoll® Prime 2500 can form lumps when added to an alkaline liquid. To avoid this, it should be added as a ready stock solution, as slurry in slight acid water or in an 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.

Market segment: Paints, coatings and inks Functions: Thickener, Water retention, Binder, Dispersing Agent, Rheology Modifier, Stabilizer Applications: Paints and Coatings, Building

In opened bags, the moisture content of Bermocoll® Prime 2500 will be influenced by the air humidity. At the temperatures above 250 °C (480 °F), charring of Bermocoll® Prime 2500 will occur. Packaging and transport: Like many industrial processed 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 surfaces.Bermocoll® Prime 2500 is packed in polyethylene plastic bags. Net weight 20 kg. We recommend emptying the bags from the bottom. The empty bags can be recycled or burned. Safety and handling: At high temperatures and in contact with an open flame, Bermocoll® Prime 2500 will burn slowly with the characteristics of cellulose.
