1/5New rheology modifier for Water borne coating
DISPARLON AQH-810, AQ-633E
１. Summary
There are many types of rheology modifiers in the market for water borne
formulations such as cellulosics, urethanes, acrylics and bentonites. A new polyamide
type of rheology modifier is now available which gives formulations the optimum
rheology profile for smooth application. The DISPARLON AQ-600 series andAQH-800 provide excellent shear thinning properties and improve anti-settling andspray atomization. Kusumoto Chemical has launched DISPARLON AQH-810 andAQ-633E which are new, easy to incorporate polyamide rheology additives.

2-1．AQH-810 features.
①It can be incorporated into a wide variety of resin types from water soluble toemulsion. It can be formulated with low and high co-solvents content.
②AQH-810 provides a high shear thinning rheology and easy spray atomization.
This pseudo plasticity feature improves the anti-settling and anti-sag effect.
③The product as supplied can easily be incorporated by low shear (even 3-5m/sec).
It is easily dispersed and can be post added.
④The AQH-810 network structure is created by a hybridized amide consisting ofhydrophilic and hydrophobic amide structures. It helps maintain long anti-settlingand coating storage stability without hard caking.
2-2．AQ-633E features①AQ-633E is the easier incorporation version of AQ-630.
②Easy handling soft gel.
③Provides excellent anti-settling and anti-sagging effect with higher N.V.
④Improves aluminum orientation with improved spray atomization.
⑤Provides excellent coating storage stability without hard caking or pigment settling
through it’s strong network structure.

５．Recommendable range view from co-solvent amount and hydrophilicity

As indicated in the graph above, AQ-633E and AQH-810 can be applied into wide
range of water borne coatings ranging from co-solvent less to co-solvent richformulations. In addition, they are effective with a wide range of resin types fromhydrophobic to hydrophilic.

６．Suggestion
AQ-633E and AQH-810 recommendations for best performance:①Optimum pH range is 8 to 9. Performance is lost in the acid range with agglomeration
formation.
②Direct incorporation by post addition is recommended.
③20 - 40℃ is recommendable dispersing temp. Some performance may be lost at
dispersing temperatures above 40C.
④Optimum dosage is around 2.0～8.0％ (on total formula weight). To reach the target
viscosity, a combination of thickeners may be required.
