Dispersant Ultra FA 4430 is a product offered by BASF with the following characteristics and properties:

Chemical Properties:

It is a non-ionic surfactant and a fatty-acid-modified emulsifier.

Its chemical formula is C₁₄H₃₀O, and its CAS number is 68439-50-9, and EINECS number is 500-213-3.

Functions as a Dispersant:

Excellent Pigment Wetting: It has excellent pigment wetting properties, which means it can effectively coat the surface of pigments, making them more easily dispersed in the medium.

Good Dispersing Performance: It shows excellent wetting and dispersing properties in aqueous, binder, and solvent-free pigment pastes. This helps to create stable and homogeneous formulations by preventing the aggregation and sedimentation of pigment particles.

Flow Property Enhancement: It can provide outstanding flow properties even at high pigment loading, which is beneficial for the application and processing of coatings and inks.

Compatibility and Stability:

Compatibility with Binders: In topcoats based on different binder types, it improves pigment wetting, thereby increasing the gloss and color intensity of the paint, especially in combination with organic pigments. It also shows excellent results in water-based alkyds, polyester resins, and aqueous polyurethane emulsions.

Improved Storage Stability: It is used to improve the storage stability of emulsion paints and their compatibility with cement and lime.

Other Advantages:

Defoaming Properties: It has certain defoaming properties, which can help to reduce foam generation during the production and application processes.

Good System Compatibility: It has the advantages of being non-toxic, odorless, non-irritating, resistant to hard water and acid-base, and having good compatibility with the system.

Applications:

It is suitable for use in various coating products, such as textured finishes, exterior and interior paints.

It can also be used as an anti-static agent and emulsifier in cosmetics, although there is a high possibility of causing skin irritation and acne. Additionally, it is used in products like washing & cleaning products, plant protection products, fertilizers, air care products, lubricants and greases, and polishes and waxes.
