YH-ED
Rheological Additive
----------------------------------------------------------------------------------------------------------------------
YH-ED is a modified bentonite for water-based systems
1. Advantages:
☆ Good thickening and thixotropy property. ☆ Good swelling property. ☆ Good transparency. ☆ Economical in price. ☆ High purity
2. Typical Properties:
Color : Light White
Appearance :Free Flowing Powder
Moisture (@105℃,2 hrs) :≤12.0%
Fineness through 200 mesh : ≥95%
Whiteness :>70
Surface viscosity( c.ps) : >300
PH value (10%susp ension ) :9-13
3. Typical Applications:
● Natural stone coating
● Pigment thixotropic agent
● Emulsion paint
● Pigment
4. Incorporations:
YH-ED can be added directly in powder form. No need for polar actiator or pre-gel. Recommended procedures are as follows:
A.Water
B. YH-ED(Dispersing at high speed shear for 15-30minutes).
C. Other additives (film-forming agent,dispersing agent,defoaming agent, etc.)
D. Pigment and filler (Mixing and dispersing).
E. Emulsion (Mixing).
F. Post correct.
5. Recommended Levels:
The amount of YH-ED rheological additive required depends upon the specific system and the degree of thickening or other properties desired. Addition levels are typically between 0.5%-3.0% based on the total formulation weight.
