DISPERSANT DMA 40 is an APEO free, highly effective liquid dispersant for 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.
The use of DISPERSANT DMA 40 is very favourable in case of storage stability of highly filled emulsion paints and mostly avoids thickening.

Normally DISPERSANT DMA 40 is added in emulsion paints with 0,1-0,3 % calculated on pigments / extenders. The really required quantity essentially depends on the type of the pigments / extenders used and should be determined from case to case (determination of the optimum quantity of the dispersing agent.) DISPERSANT DMA 40 can be added alone or combined with polyphosphates (i.e.Calgon N).
For combined addition mixing proportions of 1:2 to 2:1 has proved to be effective. If more than 1 % of DISPERSANT DMA 40 is added it should be tested whether the water sensibility of the film increases. In emulsion paint procedure DISPERSANT DMA 40 normally has to be added before addition of pigments / extenders. If necessary DISPERSANT DMA 40 can also be applied later.
