NUOSPERSE FN 270 Key Benefits Excellent paint stability and colour development APEO-free and labelling-free Very low foaming Newly developed APEO and labelling free non-ionic dispersing and wetting agent Innovation Compliance High Performance
Introduction Negative impacts on health and the environment have steered product developers to seek alternatives for alkyphenolethoxylates (APEO) in all possible applications. Traditional APEO-containing wetting and dispersing agents work very well in paints and colorants and it is a challenge to obtain the same properties with environmentally friendlier chemistries. Elementis has risen to this challenge and has developed a universal, non-ionic, APEO-free dispersing and wetting agent that meets the stringent demands of safety, health and the environment while also providing the same pigment dispersing power and equal application properties (sag, levelling, brush drag). NUOSPERSE FN 270 is an APEO-free and labelling-free universal pigment wetting and dispersing agent for a wide variety of latex paints. It provides the wetting and dispersing properties of traditional APEO-containing additives but with much easier handling and without the disadvantages of regulatory labelling. It is an effective replacement for Nonylphenol-10 EO. It shows superb storage stability, both as a product itself and when used in a paint.

However, it is recommended to start by replacing Nonylphenol-10 EO on a one-to-one basis (as supplied). Typically, 0.1 to 0.5% would be used in coating formulations whereas 3 to 12% would be required as a vehicle for a pigment concentrate.

APEO-free and labelling-free Global legislation drives the development of APEO-free products, especially when they can end up in the open environment (water) and act as endocrine disruptors. Product R-Phrase Labelling Nonylphenol-10 EO R22 Harmful if swallowed R41 Risk of serious damage to eyes R51/53 Toxic to aquatic organisms, may cause long-term adverse effects in the aquatic environment Market reference R38 Irritating to skin R50 Very toxic to aquatic organisms NUOSPERSE FN 270 None None NUOSPERSE FN 270 is APEO- and labelling-free which supports the growing demand for environmental friendly products and compliance with different Ecolabelling systems. (Ecolabel, Blue Angel...) Freeze-thaw stability The test results below show that NUOSPERSE FN 270 is still liquid at - 12 C storage. After 6 hours thawing it is absolutely clear. Initial at -12 C Nonylphenol Market NUOSPERSE 10 EO reference FN 270 This property is a huge advantage for storage and transport in the winter time. After 6 hours thawing 3
Less foaming than APEO The following shows the results of a foaming test. The products were shaken for 2 minutes on the Scandex at 0.4% loadings in water. The pictures were taken immediately and after 4 hours at rest. Initial after shaking 4 hours after shaking Nonylphenol-10 EO Market reference NUOSPERSE FN 270 Nonylphenol-10 EO Market reference NUOSPERSE FN 270 Good paint stability The NUOSPERSE FN 270 was tested in 4 standard decorative paint systems: PVC 30.0%; Pure Acrylic ; ; Vina-VeoVa ; Vinylacetate/Ethylene (VAE) All paints were made with an equal loading level of the dispersing agent. The following rheograms show the paint viscosity initially and again after storage at 40 C. A lower viscosity indicates more effective dispersion.
