Dispersant ASP 40

Dispersant ASP 40 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.

• Appearance: Greenish yellow clear liquid
• Composition: Ammonium salt of polycarboxylic acid
• Solid Content % ± 0,5: 40
• Viscosity 25°C LVT 2/60: 400 cps max.
• Density at 20°C: Approx. 1,2 g/ml
• pH: 6.5 – 7.5
• Solubility in Water: Soluble in Water
• Storage Stability: Protect from freezing

Dispersant ASP 40 is generally added in emulsion paints with 0,1 – 0,5% calculated on pigments / extenders. The actual quantity required 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 ASP 40 can be added alone or combined with nonionic compatibilizers. For combined addition mixing proportions of 1:2 to 2:1 has proven to be effective. If more than 1% of Dispersant ASP 40 is added, it should be tested whether the water sensitivity of the film increases. In emulsion paint procedure, Dispersant ASP 40 normally has to be added before addition of pigments / extenders.
