Thickening and thixotropic agent for aqueous systems. Application

Xanthum Gum is suitable for use as a thickener and stabilizing additive for all aqueous coating systems and technical applications such as water thinkable lacquers, dispersion paints and plasters, glues printing inks, silicon paints as well as pigments and filler preparations.

Xanthum Gum is a natural biopolymer based on poly saccharides. The average molarity is approximately 2x106 g/mol. IT is soluble in cold and hot water and yields highly viscous, shear and thinnable solutions. It is insoluble in most organic solvents. Xanthum Gum is fully soluble in water and mixtures of organic liquids with at least 60% water content. Ethanol content of up to 50% is also possible.

Xanthum Gum is stable in anionic and non Ionic systems. In cationic systems, it is not always compatible.

The solutions are pH- and temperature stable. There is almost no change in viscosity from pH 2-12.The temperature has relatively less influence on the on the viscosity of a solution of Xanthum Gum.

Xanthum Gum prevents settling of pigments and fillers and separation of the liquid phase during storage. Application is made easier through pronounced structural viscosity .The viscosity sinks when the shear force is increased. It rapidly returns to the starting value when the shear  force is increased. It rapidly returns to the starting value when the sheer force is removed. The product is compatible with most commonly used binders and thickeners used in the coating industry.

Conservation

Solution of Xanthum Gum should be preserved if they are to be stored for more than 24 hours. Compatibility is given with preservatives which are common in the paint industry.

Storage conditions

Xanthum Gum can be stored for at least 24 months at room temperature and dry conditions.

Xanthum Gum should be stored cool (max 30° C) and dry (max 70% relative humidity) in closed packages.

Package Sizes

Paper / Hdpe bag (25kg net)

Safety Regulations

According to regulation (EC) No 1272/2008 Xanthum Gum is not classified as a dangerous product and therefore does not need to be labeled.

Due to the fine fractions of the product, measures for dust protection must be heeded and the buildup of electrostatic charge must be avoided.
