Description

NUOSPERSE® FX 605 is a low-foaming pigment dispersing agent designed for aqueous systems. It's formulated to counteract pigment flocculation in weak acid, neutral, and strongly alkaline media. Here's an overview:

General Information: NUOSPERSE® FX 605 is stable against hydrolysis, retaining its activity even after extended storage of the coating system.

Physical Properties:

Appearance: Clear liquid
Active Content: Approx. 45%
pH: 8 - 9 (5% solution in water)
Density: Approx. 1310 kg/m3
Viscosity: Max. 500 mPa.s (30°C)
Colour: Max. 5 Gardner
Chemical Composition: Sodium salt of a polymeric carboxylic acid
Solubility: Soluble in water

Applications and Properties: NUOSPERSE® FX 605 is used as a dispersing agent for various pigment types and fillers in aqueous media, such as titanium dioxide, calcium carbonate, talc, kaolin, and modified clays. It functions as a deflocculant, reducing the viscosity of the pigment paste, and can disperse highly concentrated pastes. The product stabilizes milled and de-agglomerated particles, preventing flocculation.

Key Features and Consequences:

NO-VOC: Suitable for use in NO-VOC paints
Ammonia-free: Ensures low-odor paints
Narrow distribution of polymer molecular mass: Enhances pigment dispersion and opacity, reduces flocculation
No foaming: Reduces demand for defoamer
Insensitive to hydrolysis: Provides long-term stability of the paint

Incorporation: The quantity of NUOSPERSE® FX 605 depends on the pigment type and milling method. It's recommended to start by adding NUOSPERSE® FX 605 to water, then incorporate pigments and fillers. Dosages vary based on the specific pigment or filler.
