Features & Benefits

Product Highlights

CLiQFLOW 681 is recommended as single-or co-thickener in modern, environmentally friendly high value paints or coatings. The rheological additiveimproves leveling behavior, gloss development, hiding power, brush drag and reduces spattering during roller application.

CLiQFLOW 681 associates with binders as well as pigments in an aqueous environment. The association with pigments and extenders makes the product particularly suitable to produce stable less pseudoplastic pigment concentrates.

Applications & Uses

Application Method
Coating Type
Level of Use

CLiQFLOW 681 can be added at any production stage. Pre-dilution of the thickener is not requiredbut might be beneficial in highly reactive coating systems.

The optimum loading level should be determined for each system using a loading ladder study. A levelbetween 0.3 –2.0 %on total is typically required to achieve the required properties.
