Indofil ASE-60

Formulation Guidelines :

ASE-60 Rheology Modifier can be added to the mill-base, to the letdown, or as a post addition without affecting performance properties, as long as the medium is sufficiently alkaline during the incorporation and sufficient mixing is available.Supplied as a low viscosity emulsion, ASE-60 Rheology Modifier is easy to pump or pour and therefore very suitable for bulk handling and/or automatic metering equipment. ASE-60 Rheology Modifier can be incorporated at different stages of formulation, provided that enough base is available to neutralise the thickener and additional base is used to adjust pH. In all cases it is recommended to add ASE60 Rheology Modifier diluted 1:1 with water.Adding ASE-60 Rheology Modifier as one of the final ingredients in the letdown is convenient in the laboratory to determine the approximate amount of thickener that will be needed to achieve the desired viscosity, or in the plant to make final viscosity adjustments. Addition of ASE-60 Rheology Modifier in this manner assumes reasonably good agitation in the vessel. Less than ideal mixing can be compensated for, in many cases, by adding the thickener emulsion more slowly. In any case the addition of the appropriate amount of base prior to the ASE-60 Rheology Modifier is essential in order to avoid reduction in pH and subsequent pigment flocculation.

Specifications :
  • ASE-60 rheology modifier is designed to adjust the viscosity of
    interior and exterior coatings.
  • Its primary use is to increase low-shear viscosity to add
    structure to roller applied coatings.
  • ASE-60 rheology modifier can be used in most coating formulations
    where it provides a balance of sag and syneresis resistance, and a creamy in-can appearance.
  • Used at low levels, ASE-60 Rheology Modifier will improve
    anti-settling properties of coatings without affecting other application properties.
  • Delivered as a low viscosity liquid, ASE-60 Rheology Modifier is
    very easy to handle and incorporate into the coating.
  • For viscosity build-up pH of the coating must be at least neutral
    or in the alkaline region.
  • It is resistant to microbiological or enzymatic degradation,
    thereby avoiding viscosity loss in the coating.
Typical Properties :
  • Appearance Milky white liquid
  • Solids content 27.5-28.5 %
  • pH 2.1-3.5
  • Density 1.06 g/cm3
  • Viscosity Neutralized 3000..6000 mPa·s (Brookfield LV,
    spindle 3@ 12 rpm, 25°C)
