ANTIGEL 6217

Multifunctional additive with good wetting and dispersing properties for solvent borne and water-based coating systems

Chemical base: Mixture of surface active agents with antioxidant, free of oxime
Properties: ANTIGEL 6217 has the following properties:

• Stabilisation of viscosity (in oxidative drying systems)
• Retardation 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 6217 is based on the synergistic activity of the components.

1. Viscosity stabilisation
The stabilisation is based on the oxygen binding properties of the antioxidant. 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 6217, calculated on solids content. It is necessary to disperse ANTIGEL 6217 thoroughly.
Applications: ANTIGEL 6217 is mainly used in solvent containing systems based on alkyds, alkyd / melamine, nitrocellulose combinations and polyesters. The above mentioned properties of ANTIGEL 6217 are also suitable for coating systems based on alkyds, alkyd/acrylic and other systems.
Technical data:
(Guide values)
Appearance : light brownish to brown liquid
Density (ISO 2811-1) : 0,85 g/cm³
Flash point (ISO 1523) : 27 °C
Processing: ANTIGEL 6217 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 total formulation is common. 4.0 – 6.0 % calculated on the solids content is used when reworking thickened batches.
Storage: Keep ANTIGEL 6217 in a cool, well-ventilated place. Occasionally, slight sediment is formed. There is no need to stir up the sediment. ANTIGEL 6217 contains a natural raw material, which can lead to variations of the color tone. In both cases the quality is not adversely affected.

Subject to appropriate storage, the described properties of the described properties of ANTIGEL 6217 remain stable for at least 2 years, provided the original container is closed after use.
Packaging: 50/175 kg drum
