Dispersant ASP 42 is an APEO and Formaldehyde free, highly effective dispersant for anionic pigments and extenders in aqueous systems. The product is compatible with all common synthetic emulsions, creates little foam and is effective in a wide pH range.
Dispersant ASP 42 is generally added in emulsion paints with 0,1 – 0,5% calculated on pigments/ extenders. The actual quantity required essentially depends on thetype of the pigments/ extenders used and should be determined from case to case (determination of the optimum quantity of the dispersing agent). Dispersant ASP 42 can be added alone orcombined with nonionic compatibilizers. If more than 1% of Dispersant ASP 42 is added, it should be tested whether thewater sensitivity of the film increases. In em ulsion paint procedure, Dispersant ASP 42 normally has to be added before addition of pigments/ extenders.
