Still having headache with finding the right thickener to achieve desired level of rheology?
In waterborne (WB) industrial paint, rheology is a very important factor in terms of handling and applyting paints. And the rheology is depends on the thickener that is used in the paint formulation.
We have observed from our existing WB industrial paint makers that they commonly face problems such as:
- Excessive viscosity
- Synersis & Sedimentation
- Bad Resistance
- Sedimentation before Spray
Are you facing these problems? What could be the possible solution to this?
Have you heard about ASE Thickener?
ASE (Alkali soluble emulsion polyacrylate) is normally being applied as a thickener in water-based coatings. This tend to be active at high pH level and
they are steeply shear-thinning and suitable to high-viscosity, thick-film applications such as caulks, mastics, EIFS finishes, driveway sealers and craft paints.
Among the ASE thickeners that we are holding, we normally recommend THIXOL 53L, an unique acrylic thickener, which has the following features:
- 30% active, easy to handle
- Thickening in water and self-association
- Unique hydrophobic modification, self-association, provide strong low shear viscosity and good anti-sagging performance
- Good thixotrophy
- Good sprayability
Efficacy of Thixol 53L
We have tested the efficacy of Thixol 53L by the following test method:
- 100% thinned by de-ionized water
- Soak the steel panels in the paint
- Take them out and keep them vertical
- Compare after 5 minutes
The result showed that Thixol 53L maintained a good paint homogenity after the dilution with no settling like the following:
|KU (100% thinned)||52.1||52.4||49.4|
Example of Our Pearlescent Paint Formulation & Test Results
Our recommended formulation is as given below:
|Function||Raw Material||% wt||Condition|
|Water||DIW||37||Pre-mix and add into pre-mix pearlescent pigment|
|Coatex Thickener||Thixol 53L||1.5|
|Co-solvent||BG||10||Pre-mix and stir well|
|Pearlescent Pigment||Golden Pearl KC300||6.7|
|Coatex Thickener||Thixol 53L||0.2|
|pH > 8.5|
And the stability test result of the formulation was as given below:
|Storage Stability||Parameter||Test Result|
|Thixol 53L||Dosage %||1.7|
