Résumé : |
Solvent-based emulsion paints are still the state of the art for many coating applications. However, interest continues to grow in binders that permit the formulation of solvent-free emulsion based paint systems. This requirement can be met by selecting polymer dispersions with an appropriate minimum film-forming temperature (MFFT). Therefore, the similarities and differences between pure (or straight) acrylic (Ak) and acrylic/styrene (Ak/S) dispersions with different MFFTs will be discussed In the following. Other variables that we considered are the pigment volume concentration (PVC in the range of 46 to 68%), the grade of titanium dioxide pigment and the composition of the extenders used in the formulation. |

- Raw materials used
- Results of the tests
- Hydrophobic binder supports film formation at 5°C
- Solvent-free paints absorbs more water then solvent-containing
- Colour change due to artificial weathering
- Chalking results depends on binder type |
