ANTIGEL® is a multifunctional additive with good wetting and dispersing properties for solvent-based and water borne coating systems, biodegradable. 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.

Functions: Dispersant, Wetting Agent

Mode of Action

The multifunctionality of ANTIGEL is based on the synergistic activity of the components.

1. Viscosity stabilization
The stabilization 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 color 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.

Processing Information
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 and Handling
Subjected to appropriate storage, the described properties of ANTIGEL remain stable for at least 2 years, provided the original container is closed after use.
Storage and Handling
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.
