★★★Wetting Dispersant LD-1918
Wetting Dispersant LD-1918
First, summary
Ld-1918 dispersant is a kind of water oil universal dispersant with no volatile solvent and high efficiency of zero v0c, which has 100% effective components. It can significantly improve the wetting of pigment, fully reduce the time required in the grinding process and stabilize the pigment dispersion. It is suitable for grinding and stabilizing inorganic pigment and carbon black, especially titanium dioxide pigment, which can significantly improve the wetting of pigment. Through the steric hindrance, the pigment flocculation can significantly reduce the grinding viscosity, increase the pigment content, fully reduce the grinding time, and significantly improve the leveling performance and increase the gloss. It can prevent the flocculation of pigment, stabilize the hue and coloring power, increase the color development and covering power of pigment, and prevent the occurrence of floating color / blooming.
