 The function of dispersing additives |
| Chemical base: | Antioxidant with additives in solvent mixture | |
| Properties: | ANTIGEL KF-D has the following properties: • Stabilisation of viscosity against air oxidation • Prevention of skinning • Improved wetting • Prevention of settlement • Reduction of dispersing time • Reworking of thickened batches • Removal of floatation phenomena • Promotion of flow and gloss |
|
| Mode of action: | The multifunctionality of ANTIGEL KF-D is based on the synergistic activity of the components. 1. Viscosity stabilisation The stabilisation is based on the oxygen binding properties of the antioxidant. ANTIGEL KF-D improves flow and through-drying. 2. Wetting and dispersion The wetting component of ANTIGEL KF-D reduces the interfacial tension between the usually hydrophilic pigments and the hydrophobic binder. The pigments are well distributed resulting an optimum depth of colour. Dispersion time, floatation phenomena and sedimentation 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 KF-D, calculated on solids content. It is necessary to disperse ANTIGEL KF-D thoroughly. |
|
| Applications: | ANTIGEL KF-D can be used in almost all water-based and solvent borne coating systems. | |
| Technical data: (Guide values) |
Appearance : clear, colourless to slightly yellowish liquid Density (ISO 2811-1) : 0,94 g/cm³ Flash point (ISO 1523) : > 60 °C |
|
| Processing: | ANTIGEL KF-D should be added to the mill base in order to get optimum use of its wetting properties. It is recommended to establish the dosage by preliminary experiment. ANTIGEL KF-D is a highly suitable multifunctional additive and can be used up to 15.0 % on solids content depending on the field of application. When mainly used as anti-skinning additive, 0.5 - 1.5 % dosage are recommended. For regeneration of thickened batches an amount of 5.0 % should be used and 2.5 % - 15.0 % as dispersing additive. |
|
| Storage: | Keep ANTIGEL KF-D in a cool, well-ventilated place. Occasionally, slight sediment is formed, which does not adversely affect the quality of ANTIGEL KF-D. There is no need to stir up the sediment. Subject to appropriate storage, the described properties of ANTIGEL KF-D remain stable for at least 2 years, provided the original container is closed after use. | |
| Packaging: | 50/175 kg drum | |
