Product Details
YH-170 is an organoclay (tetraallkyl ammonium bentonite) for solvent-based systems of low,medium and high polarity.
1. Advantages:
? High gelling efficiency over low, medium and high polarity organic liquids.
? Produce reproducible thixotropic consistency over a wide temperature range.
? High viscosity and excellent thickening property over a wide temperature range.
? Imparts particle suspension, preventing hard settling of pigment and fillers.
? Exerts strong film reinforce action in organic binder systems.
? High purity:high percentage of montmorillonite,free cristobalite <1%.
? High efficiency:save 30%dosage compared with ordinary grades.
? Good dispersion:self-activated in medium/high polar system.Its fineness can reach 10µ or even less.
2. Typical Properties:
Color | Appearance | Density | Moisture | Fineness through 200 mesh | Loss on Ignition |
Light White | Free Flowing Powder | 1.85g/cm3 | =3.5% | =99% | =42% |
3. Typical Applications:
?Acrylic paint | ?Solvent epoxy paint |
?Alkyd paint | ?Wooden paint |
?Baking paint | ?Zinc-rich paint |
?Decorative paint | ?Inks(mineral oil,vegetable oil) |
?Industrial paint | ?Varnish |
?Marine paint | ?Lubricating grease |
?Non-solvent epoxy paint | ?Cosmetics |
?Polyester paint |
4. Incorporations:
YH-170 belongs to the unconventional type of organoclays group, being an easy-to-disperse, self-activated organoclay, YH-170 does not require a chemical (polar) activator to reach the proper level of delamination of the organoclay platelet stacks.
YH-170 can be added at any point in the manufacturing process. If addition is made with polar activator or after grinding,better performance can be expected.
Polar Activator: Dosage of polar activator( such as propylene carbonate, 95%ethanol , acetone or 95% methanol) is 20%-30% by weight of YH-170.
It is always recommended to determine the proper level of addition by experiment. Either defect or excess of chemical activator would result in poorer viscosity development.
5. Recommended Levels:
The amount of YH-170 rheological additive required depends upon the type of organic system and the degree of thickening or other properties desired. Addition levels are typically between 0.2%-0.8% based on the total formulation weight.
