Feature introduction
SilibaseDPL-9890 prevents pigment flocculation by establishing a spatial barrier effect between pigment particles. It can give isoelectric point to pigment particles and prevent flocculation of non isoelectric pigments. Because it can keep the pigment in the minimum particle size state without flocculation, it can achieve higher gloss and higher coloring strength, and improve the transparency and hiding power. SilibaseDPL-9890 significantly reduces the viscosity of titanium white grinding system, improves leveling, increases the pigment concentration of titanium white, and ensures that the white paint does not turn yellow.
SilibaseDPL-9890 is suitable for stabilizing the dispersion of inorganic pigments, especially titanium dioxide. In general, it can be used in combination with amine anchored dispersants such as SilibaseDPL-9457 and 9459.
Packaging and shelf life
Due to the acidity of SilibaseDPL-9890 itself, this product may catalyze and accelerate the cross chain of baking paint system. The change of viscosity of paint shall be checked during storage.
Due to the extremely high molecular weight of SilibaseDPL-9890, turbidity and separation may occur when the temperature is lower than + 18 ℃. It can be heated to room temperature before use, mixed evenly, and the product quality will not be affected.
