BERMOCOLL Prime 3500 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.
Methyl ethyl hydroxyethyl cellulose
BERMOCOLL Prime 3500 can be used as a rheology modifier in all types of latex paints. BERMOCOLL Prime 3500 is recommended when high in-can as well as enhanced application viscosity is required. BERMOCOLL Prime 3500 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 3500 is easily dispersed in cold water of pH 7 or less. BERMOCOLL Prime 3500 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.
