NanoUse ZR
Through patented production technologies Nissan Chemical has developed an unprecedented water-based zirconia sol. NanoUse ZR offers excellent stability at a high concentration with the following points of interest:
- The primary particle size of zirconia in sol is around 7 nm and exists as micro-colloidal zirconia in a globular aggregate form which has a large surface area with excellent binding properties.
- It reaches its equipotential point at pH 5.5~6.5 and is stable in acid and alkali systems.
- Because alkali zirconia sol has properties similar to silica sol, it can be mixed with silica sol. Acidic zirconia sol can be mixed with alumina sol.
- Acidic zirconia sol exhibits good compatibility with alcohols.
- It does not contain chloride ions (Cl), as conventional zirconia sols do.
- High baking strength as well as good burning strength can be achieved.
Additionally, we provide a hybrid sol with an enriched binder function and a micro-particle sol that is doped by yttria so that you can choose the one that suits your specific application.
