Sapetin D 27

• Highly negative charge.
• Stable against hydrolysis even in alkaline media.
• Excellent dispersing effect in a broad pH value range.
• Has chelating properties (e.g. bonding iron).
• ls fixed to filler and pigment surfaces.
• Particularly effective in dispersing silicate fillers, e.g. kaoline.
• Low addition rates suffice for high efficiency.
• Very low odor level, free of preservatives or organic solvents.

Sapetin D 27 has a highly negative charge; it is adsorbed to filler and pigment surfaces and thus creates a repulsion effect between the single particles, so that highly concentrated dispersions with reasonable viscosity can be produced. Due to the high stability of Sapetin D 27 against hydrolysis a stable dispersing effect is ensured thus counteracting agglomeration.

Sapetin D 27 is a dispersant for mineral fillers, e.g. kaolins, calcium carbonate minerals, metal oxide pigments, etc. It is also a plasticizer for self-leveling floor finishes, ceramic compounds, concrete-bonding mortars, cement finishing coats, and cement products. For the production of porcelain the addition of Sapetin D 27 allows to take the green molded articles smoothly out of the gypsum molds.

The optimum dosage for Sapetin D 27 can be determined by plotting a dispersant requirement curve. By this means, any tendency to flocculation can be counteracted.
