Résumé : |
Many industrial, maintenance and marine spray coatings have very high requirements in terms of sag stability and layer thickness – around 1000u% or greater in one pass. These specific needs limit the selection of suitable rheology modifiers. Novel diamide-based additives now offer processors flexibility over a wide range of activation temperatures and improved viscosity at low shear forces. |

Many industrial, maintenance and marine spray coatings have very high requirements in terms of sag stability and layer thickness – around 1000u% or greater in one pass. These specific needs limit the selection of suitable rheology modifiers. Novel diamide-based additives now offer processors flexibility over a wide range of activation temperatures and improved viscosity at low shear forces.
- Rheology modifiers for a wide range of solvents
- Activation at low temperatures
- Improved viscosity at lower shear forces
- Robust intercoat adhesion
- Highest viscosity and layer thickness with millbase addition
- FIGURES : 1. Flow characteristics provided by the various classes of rheological modifiers – 2. Schematic representation of the mechanisms of action of a diamide-based rheology modifier after correct activation – 3. Optimum activation temperature range – 4. Rheology curves of a solvent-based protective and marine coating equipped with 1% of the relevant rheology modifier activated at 63°C – 5. Viscoelastic behavior of test systems. The yellow line indicates the point at which shear was stopped after application – 6. Intercoat adhesion testing – 7. Low-shear viscosity data at 0.1 s-1 and the maximum applicable layer thickness by blade application in accordance with the specified incorporation and activation method |
