Deuterol 201 E is a defoaming dispersing agent for fillers and pigments in water soluble and water miscible primers and lacquers. The wetting effect of Deuterol 201 E in primers and one-coat lacquers, which are applied to badly degreased metal substrates, considerably improves the adhesion of the coating film to the metal substrate. The product also shows a defoaming effect in the manufacture as well in the processing of water dilutable systems.

Deuteron ND 210 is a wetting agent with a cationic effect. It reduces the surface tension of organic solvents or binding agent solutions and thus supports the dispersion process, making it more cost-effective.

Deuteron ND 210 also allows a more economical use of pigments since both the hiding and the coloring powers largely depend on the dispersion conditions. The much-dreaded flooding and floating of pigments can be prevented with Deuteron ND 210.

Deuteron ND 210 is suitable for the production of pigmented coating materials based on oxidative and on physically drying binding agents. The wetting-promoting properties of Deuteron ND 210 are particularly advantageous for the production of highly filled systems, such as pigment paste. Likewise, the agent is also suitable for coating systems for which both of the above aspects are desirable.

Deuteron ND 953 helps to prevent the uncontrollable increase in viscosity which can arise in presence of certain pigments and fillers in heavily-filled aqueous systems. The required rheological properties of the paint or coating material can be obtained just through the character of the used binder or by addition of a suitable thickener.

The presence of Deuteron ND 953 improves the storage stability. Unwelcome thickening during storage will be avoided or limited.

Deuteron ND 953 is used in aqueous paints and coating materials, e.g. masonry paints, fillers, aqueous primers, water-based bituminous emulsions. The product is also suitable for use in water-based pigment preparations. It is most effective in presence of inorganic pigments and fillers.

NUOSPERSE FA 615 is a wetting and dispersing agent.
