Application Field
Dispersion of nano inorganic powder slurries such as nano alumina

Key Feature
Provides steric hindrance effect; adding it to the slurry can significantly reduce the viscosity of nano inorganic powder slurries and improve slurry fluidity.
Reduces undesirable phenomena such as slurry sedimentation and flocculation, and enhances the storage stability of slurries.

Usage Method
Add XOANONS® LD 1139 into the solvent and stir evenly, then add the powder according to the formula ratio for dispersion and grinding together.

Recommended Dosage
Addition amount (as purchased), based on nano inorganic powder materials: 1-10%

Storage Stability
Seal and store in a dark place. The shelf life is 24 months in the unopened original packaging. Products beyond the shelf life can be used continuously after passing inspection. Tightly seal the container immediately after use if it is not completely empty.

Package
25 kg (plastic barrel)
