Choosing Between 10 nm and 20 nm
Available in both particle size. As a matter of thumb, smaller particles scatter less light, hence the 10 nm grade is the more probable option for transparent or light-colored coatings. The 20 nm grade may be appropriate for those compositions where ease of handling is desired. The proper grade will depend on your binder, additives and film needs thus a little trial is the best way to determine. If you submit a query, tell us your desired clarity.
Key Features
- Two particle sizes: evaluate clarity vs handling in your own system with 10 nm and 20 nm possibilities.
- Water as solvent: The dispersion is intended for water based systems. Please validate the VOC values of your whole formulation.
- γ-alumina: The surface activity of γ-phase alumina is normally correlated with adhesion and compactness of the film. Check the impact on your own coating.
- Liquid format The substance is dispensed as a dispersion so you do not need to scatter dry nano-powder manually.
Applications in Paints and Coatings
This Nano alumina dispersion liquid (gamma phase) is suitable for waterborne paints and coatings requiring a clear or light-colored film. If you want the best transparency, then go with the 10 nm grade. If handling is the biggest issue, then consider the 20 nm grade. The data provided does not include the use of paints and coatings outdoors, please contact us to discuss your approach.
Formulation and Testing Notes
Try a brief compatibility test on your formulation before scale-up using the product. The pH of the dispersion is 8–10, and colloidal alumina may be subject to pH fluctuation. Flocculation or gelation may be caused by very acidic additions or unsuitable binders.
When you make the dose calculation write the 20% concentration and pH range so the trial batches are easier to compare. Begin with thin sheets, since a heavy coating of dried alumina might shatter. We do neither recommend dose nor maximum film thickness here, please approach our staff for help.
Before You Order
If you are looking for Nano alumina dispersion liquid (gamma phase), please provide the following information:
- Target particle size: 10 nm or 20 nm
- Binder system type and coating
- Film thickness and clarity requirements
- Anticipated volume
We’ll walk you through these points. Please also request us to validate the packaging, storage conditions, shelf life and papers accessible.

FAQ
Q: What particle sizes are available?
A: The dispersion is available in 10 nm and 20 nm.
Q: And the pH value? What is the concentration?
A: The concentration is 20% and the pH value is 8-10.
Q: Does the dispersion respond to pH change?
A: Alumina colloidal may be. Acidic additives or binders that are not suitable may induce flocculation or gelation. Test a small batch.
Q: What grade should I use for a clear coating?
A: In general the smaller the particle the less light it scatters . So the most probable beginning point is 10 nm . Tell us what kind of coating you are after and what clarity you want and we will assist you choose a grade.
Q: What are the storage conditions, shelf life and packaging sizes?
A: No information are provided in the specified specs. Please call to confirm them.
