Dispex® Ultra FA 4480

Solution of modified fatty alcohol polyglycolether in water

• Low molecular weight dispersants are an established class of surfactant type products and are categorized according to their chemical structure as anionic, cationic, electro-neutral or non-ionic. The molecular weight of these products is low, usually between 300 and 2,000 g/mol.
• Low molecular weight type dispersing agents are well established products in the industry and their broad applicability and compatibility is especially appreciated.
• In this range, also mono functional oleo-alkylene oxide block copolymers are offered, which provide excellent wetting and dispersing properties in binder and solvent-free, aqueous pigment pastes.
• In this group of products excellent alternatives to alkylphenol ethoxylate (APEO) based surfactants can be found, allowing the paint producer to formulate so-called universal pigment concentrates which are suitable for both water- and solvent-borne paints.

Schematic representation of surfactant-type low molecular weight dispersants.

• Dispex® Ultra FA 4480 shows excellent wetting and dispersing properties in aqueous, binder and solvent-free pigment pastes.
• It provides outstanding flow properties even at high pigment load.
• Dispex® Ultra FA 4480 improves pigment wetting and therefore also increases gloss and color intensity of the paint, especially in combination with organic pigments.
• Dispex® Ultra FA 4480 shows excellent results in waterbased alkyds, polyester resins and also in aqueous polyurethane emulsions.

The dosage used in pigment pastes strongly depends on the actual pigments. Typical addition levels for pigment pastes, calculated on the weight of pigment are as follows:

• 1000KG Steel/Plastics IBC
• 220KG Plastics Drums
