RHEOLATE® FX 1010 is an associative thickening agent primarily used in aqueous coatings, such as emulsions, dispersions, and emulsion paints. It's a high-efficiency polyether polyurethane thickener supplied as a liquid, making it convenient to handle and ready for immediate use. Here's a breakdown of its key properties and applications:
Physical Properties:
- Appearance: Clear liquid at 20 ºC
- Active content: 50%
- Density at 20ºC (ISO 2811-2): Approximately 1070 kg/m³
- Viscosity at 23ºC (ASTM D 2196): 10 – 18 Pa.s
- Color (50% in IPA, DIN-EN 1557): Maximum 125 Alpha
- Solubility: Soluble in water and water/glycol mixtures
- Composition: Hydrophobic urethane polymer in a mixture of solvents
Application and Properties:
- RHEOLATE® FX 1010 is applicable in various aqueous systems, including emulsions, dispersions, and emulsion paints based on different polymers.
- It improves rheological and leveling properties of aqueous paints by increasing high shear viscosity and suppressing low shear viscosity, resulting in coatings with a "solvent-based alkyd" like rheology.
- Enhances film-build, brushing characteristics, and appearance compared to conventionally thickened aqueous paints.
- Acts as a binding agent, totally compatible with standard latexes used in emulsion paints, resulting in paints with higher water resistance and scrub resistance.
- Offers higher gloss levels in gloss emulsion paints compared to other thickeners.
- Provides excellent resistance to bacterial degradation and improves viscosity stability, potentially allowing a reduction in preservatives used.
Incorporation:
- Can be added to the milling paste or during the let-down stage for best results.
- Optimal dosage varies depending on desired rheology and paint system composition, typically ranging from 0.2 – 2.0%.
- In high PVC (pigment volume concentration) formulations, it may be useful to combine with cellulosic thickeners.
- Dilution methods include addition to the pigment grind or during let-down, with suggested dilution ratios provided.
Health and Safety Data:
- Consult the Material Safety Data Sheet (MSDS) for information on safe handling and storage.
