YH-170 TDS Organoclay For Coating

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.

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.
