Rheology Additives: Increasing film thickness - Waterborne systems




BYK Additive Recommendations
BYK-420

Liquid rheology additive for aqueous and water-reducible coating systems for improving antisagging and anti-settling properties. The additive is also especially suited for manufacturing aqueous pigment concentrates. BYK-420 causes thixotropic flow behavior; post-addition is possible.

Compliant with FDA and/or EU food contact regulations. 
BYK-425

VOC-free, liquid rheology additive for aqueous dispersion-based systems to improve anti-sagging and to adjust in-can viscosity. The additive is suitable for increasing the grinding viscosity of aqueous pigment pastes.

Compliant with FDA and/or EU food contact regulations. 
BYK-7420 ES

Liquid rheology additive for aqueous and water-reducible coating systems for improving anti-sagging and anti-settling properties. The additive is also especially suited for manufacturing aqueous pigment concentrates. BYK-7420 ES creates thixotropic flow behavior. Post-addition is possible.


LAPONITE-SL 25

Ready-for-use concentrated aqueous dispersion of layered silicate rheological additive for water-borne systems.
Used in highly filled surface coatings. Synergistic benefits when used in combinations with polymer based co-thickeners.
Forms low viscosity pre-mixes in water, which thicken on addition to formulations.


OPTIFLO-H 3300 VF

VOC-free associative thickener (HEUR) for aqueous systems to generate a slightly pseudoplastic flow behavior.

OPTIFLO-H 6500 VF

VOC-free associative thickener (HEUR) for aqueous systems to generate a highly pseudoplastic flow behavior

OPTIFLO-H 7500 VF

VOC-free associative thickener (HEUR) for aqueous systems, especially for spray applications, to generate a highly pseudoplastic flow behavior.

OPTIFLO-TVS VF

VOC-free associative thickener (HEAT) for aqueous systems to generate a highly pseudoplastic flow behavior.


OPTIGEL-CK

Rheology additive based on an activated phyllosilicate for aqueous systems to generate thixotropic flow behaviour.

Compliant with FDA and/or EU food contact regulations. 
OPTIGEL-W 724

Rheology additive based on an activated phyllosilicate for aqueous systems to generate thixotropic flow behaviour.

OPTIGEL-WA

Rheology additive based on an activated phyllosilicate for aqueous coating systems and dispersion-based construction applications to generate thixotropic flow behavior.

OPTIGEL-WM

Rheology additive based on an activated phyllosilicate for aqueous systems to generate thixotropic flow behaviour.

Compliant with FDA and/or EU food contact regulations. 
OPTIGEL-WX

Rheology additive based on an activated phyllosilicate for aqueous systems and mineral pre-mix mortars to generate thixotropic flow behaviour.

Compliant with FDA and/or EU food contact regulations.
