FLOWEASE 1900 Wetting & Dispersion Additive

Wetting & Dispersion Additive FLOWEASE 1900

VOC-Free Polymeric Dispersant for Aqueous Coatings, Inks & Adhesives

FLOWEASE 1900 is a high-performance, VOC-free wetting and dispersing additive developed for aqueous coating systems, printing inks, and adhesive formulations. It is based on an aqueous polyether-modified styrene–maleic anhydride copolymer, providing powerful steric stabilization for a wide range of pigments and fillers.

FLOWEASE 1900 is especially effective in the preparation of binder-free pigment concentrates, enabling high pigment loading, excellent color development, improved gloss, and reduced viscosity. The additive is suitable for inorganic pigments, organic pigments, titanium dioxide, and carbon black, making it a versatile choice for both decorative and industrial water-borne systems.

Benefits

Efficient pigment deflocculation

Steric stabilization breaks down pigment agglomerates into fine primary particles.

Higher gloss & color strength

Fine dispersion enhances optical performance of pigments.

Improved transparency & hiding power

Supports both transparent and opaque formulations.

Viscosity reduction

Lower grind viscosity enables easier processing and higher pigment loading.

Improved flow & leveling

Better rheology leads to smoother application and finish.

Formulation flexibility

Allows preparation of stable pigment concentrates for later let-down with standard binders.

Recommended Dosage Guidelines

Dosage is based on additive “as supplied” relative to pigment content. Optimize through application-specific trials.

Aqueous Coatings & Pigment Concentrates

Titanium Dioxide: 10 – 12%
Inorganic Pigments: 20 – 30%
Organic Pigments: 30 – 75%
Carbon Black: 130 – 150%

Printing Inks (Binder-Free Pigment Concentrates)

Pigment loading: 30 – 60%
Additive level: As per pigment type above

Adhesives & Sealants

Pigments: As above
Fillers: 1 – 3% based on filler weight

Incorporation & Processing Notes

Dispersion should be carried out only in water

Do not add binders, amines, or co-solvents during grinding

Add pigments or fillers only after uniform distribution of the additive

Let down pigment concentrates with standard aqueous binders after dispersion

Safety & Handling

For industrial use

Avoid prolonged skin or eye contact

Avoid inhalation of mists during handling

Use standard PPE including gloves, goggles, and adequate ventilation. Refer to SDS for complete safety guidance.

Storage

Store in original, unopened containers

Recommended storage temperature: below 50 °C

Shelf life: up to 60 months

If separation or turbidity occurs below 0 °C, warm to room temperature and stir before use
