 The function of dispersing additives |
| Chemical base: | Modified phenol derivative and methyl ethyl ketoxime (Meko) in solvent mixture with a component promoting wetting | |
| Properties: | • Stabilisation of viscosity (in oxidative drying systems) • Prevention of skinning • Improved wetting • Prevention of settlement • Reduction of dispersing time • Reworking of thickened batches • Removal of floatation phenomena • Promotion of gloss and flow |
|
| Mode of action: | The multifunctionality of ANTIGEL is based on the synergistic activity of the components. 1. Viscosity stabilisation The stabilisation is based on the oxygen binding properties of the phenolic component. The film is longer open and flow and through drying are promoted. 2. Wetting and dispersion The wetting component reduces the interfacial tension between the usually hydrophilic pigments and the hydrophobic binder, and a good distribution of the pigments into the system is the result. Reduction of dispersion time is possible in some cases. Floatation phenomena are reduced and gloss is increased. Sedimentation is largely avoided. Because of the excellent wetting, optimum depth of colour is achieved. 3. Preparation of thickened batches Often thickened batches can be worked up by the addition of 4.0 – 6.0 % ANTIGEL, calculated on solids content. It is necessary to disperse ANTIGEL thoroughly. |
|
| Applications: | ANTIGEL is mainly used in solvent containing systems based on alkyds, alkyd / melamine, nitrocellulose combinations and polyesters. The above mentioned properties of ANTIGEL are also suitable for coating systems based on alkyds, alkyd/acrylic and other systems. | |

Appearance : light brownish liquid Density (ISO 2811-1) : 0,86 g/cm³ Flash point (ISO 1523) : 29 °C |
|
| Processing: | ANTIGEL should be added to the millbase in order to get optimum use of its wetting properties. It is recommended to establish through preliminary experiment the optimum dosage. An addition of 0.5 - 1.5 % calculated on the whole system is usual. 4.0 – 6.0 % calculated on the solids content is used when reworking thickened batches. | |
| Storage: | Keep ANTIGEL in a cool, well-ventilated place. Occasionally, slight sediment is formed. There is no need to stir up the sediment. ANTIGEL contains a natural raw material, which can lead to variations of the color tone. In both cases the quality is not adversely affected. | |
| Subjected to appropriate storage, the described properties of ANTIGEL remain stable for at least 2 years, provided the original container is closed after use. | ||
