Solvent-free wetting and dispersing agent general-purpose dispersant Anjeka 6161A
DESCRIPTION
Anjeka 6161A is a wetting and dispersing agent which is used for solvent-borne automotive and industrial coatings and pigment concentrates, especially suitable for stabilizing carbon blacks and organic pigments, particularly in two-pack PU and baking systems. Anjeka 6161A can significantly reduce the millbase viscosity.
PRODUCT DATA
Composition
Solution of polyurethane with pigment affinic groups.
Typical Properties
The values given in this data sheet describe the typical properties and do not constitute specification limits.
| Amine value: | 6-9 mg KOH/g |
| Density: | 1.02 g/ml (25℃) |
| Viscosity: | 380-420 cps (25℃) |
| Non-volatile matter (20min, 150℃): | 40% |
| Solvent: | xylene/methoxypropylacetate |
STORAGE AND TRANSPORTATION
Separation and turbidity may occur at temperatures below 0℃. Warm to 20℃ and mix well before use.
ATTENTION
The surface-treatment of some organic pigments may negatively affect the efficiency of the additive. In such cases, tests with the untreated pigment of the same type may be successful. When used in coil coatings, the interaction of this cationic additive with the acid catalyst must be taken into account. Free acids or epoxy-blocked acids are more suitable than amine-blocked acids.
Application
Industrial Coatings
Characters and advantages
Anjeka 6161A deflocculates pigments and stabilizes them by means of steric hindrance. The resulting repulsion and steric stabilization prevent possible reflocculation of deflocculated pigments, so the multi-pigment system does not produce floating and flooding. The deflocculating properties of the additive increase gloss, color strength, transparency, and hiding power and reduce the viscosity of the millbase.
APPLICATION
Industrial coatings especially recommended
Automotive coating especially recommended
Protective coating systems recommended
RECOMMENDED ADDITION LEVEL
The amount of additive (supplied form) is based on the pigment.
Titanium dioxide 5-6%
Inorganic pigments 10-15%
Organic pigments 30-80%
Carbon blacks 70-140%
The above recommended levels can be used for orientation. Optimal levels are determined through a series of laboratory tests.
PROCESSING INSTRUCTIONS
For the best performance, the additive must be added into the millbase before addition of pigments. The resin and solvent components of the millbase are pre-mixed and then the additive is slowly incorporated while stirring continuously. Do not add the pigments until the additive has been fully distributed.
