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 MM 677 can be used as a matting agent in various aqueous coating systems. These can be lacquers based on acrylic dispersion, wood glazings, wood- and fur­niture lacquers, printing inks and industrial finishes (air-drying and stoving enamels).In comparison with powdery matting agents Deuteron MM 677 particularly offers the advantage of dust-free handling. The product can be easily incorporated by all common dispersing processes. When producing clear varnish, only a small rate of shear is required to incorporate Deuteron MM 677. This prevents forming of micro foam in the production batch. Even when Deuteron MM 677 is added to the mill base or the dispersion-medium, overmilling is practically impossible due to its excellent shear stability.The matting liquid is kept free of wetting agent and binder. Their presence usually limits the compatibility. Waxes or similar products are not included either. This allows for the use of Deuteron MM 677 in a wide field of applications. Deuteron MM 677 causes little cloudiness and is therefore also suitable for the use in clear varnishes.

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.
