Rheology Additive (Water Based)
The water-based thickening rheological additive Viscor is refined and modified silicate clay (montmorillonite, attapulgite, sepiolite), which is off-white or beige non-toxic, odorless, soft powder. It has excellent swelling, colloidal dispersion, suspension, thickening and thixotropyin water. It is an excellent anti-settling agent, latex stabilizer and rheology additive for water-based systems. Water-based thickening rheological additives also have good adsorbent properties, ion exchange properties, non-migrating cohesive properties, so they are widely used in water dispersion systems.
Features :
Applications:
Use Methods :
Dry Powder Method : Viscor rheology additives can be directly put into required system and dry powder.
Pre-Gel Method : Viscor rheology additive could be used a pregel: The preparation of pre-gel concentration should be according to the desired viscosity level of the stirring speed and the product of the dispersing device in order to obtain the best result. Generally speaking 2-10% (mass percentage of the whole system)/ weigh a certain amount of the product under stirring slowly added to water of 25-30 ̊C note avoid caking. After the addition, adjust the speed to 1000-1200 RPM, and disperse it by stirring for 30 minutes so that the products can sufficiently disperse into water and form a unform gel, stand it for 8-24 hours, and use it after the colloidal plays stabilized thickning effect.
