Process Aids for Paints & Coatings

Operational efficiency

Wherever hard water is a concern, wetting agents or water softeners are used to reduce the adverse effects between the electrolytes of the water and the paint components.

To understand the performance of a process aid, it is important to analyze the additive’s impact on the primary particle size distribution in the filler/TiO2 slurry. An improved primary particle size distribution in general leads to a better hiding power of the finished paint. Moreover the process aid supports the grinding of the components in the fastest possible time. Lower processing times lead to lower energy consumption as well as higher production capacity.

PRODUCT HIGHLIGHTS

  • Emulsogen LCN 158

    Emulsogen LCN 158 is used as a nonionic emulsifier for emulsion polymerization improving the shear, temperature and electrolyte stability of polymer dispersions. The recommended usage is 2% active based on monomers. In waterborne and solvent-borne lacquers (low PVC), Emulsogen LCN 158 can be used as a compatibilizer to improve tinting strength and to reduce rub-out, water absorption, and haze effects. Dosage recommendation (supply form) in waterborne acrylic lacquers is 1.3-1.9% and in solvent-borne alkyd lacquers 0.33-0.66%.When used during the premixing phase in the production of waterborne emulsion paints (high PVC), Emulsogen LCN 158 also acts as a processing aid and helps to reduce the grinding time by faster deagglomeration of TiO2 and fillers. This is especially of interest in areas of hard water. The general dosage recommendation (supply form) for this purpose is 0.3%.

  • Emulsogen TS 100 compatibilizer

    Emulsogen TS 100 is a nonionic wetting agent for use as compatibilizer in waterborne high PVC paints, as well as in waterborne and solvent-borne low PVC lacquers. The general dosage (supply form) is 0.5-1.0% in emulsion paints, 1.0-1.5% in acrylic lacquers, and 0.25-1.0% in alkyd lacquers. When used during the premixing phase in the production of waterborne emulsion paints, Emulsogen TS 100 also acts as a process aid and helps to reduce the grinding time by faster desagglomeration of TiO2 and fillers. This is especially of interest in areas of hard water. The general dosage recommendation (supply form) for this purpose is 0.24%.
