Nano ZnO Dispersion for Antistatic and UV Coatings

ZnoNova Materials

The transparent nano zinc oxide dispersion we supply to cosmetic formulators has a second life outside cosmetics. The property that makes it useful there — blocking ultraviolet without whitening the product — is exactly what a transparent protective coating or film needs, and the same material also carries antistatic and infrared-absorbing behaviour.

The material

Composition	ZnO, water, dispersing aid — pale yellow transparent liquid
Solid content	5%
UV attenuation	Reflects and blocks 290–380 nm, covering UVB and UVA
Other properties	Antistatic · infrared absorption
Morphology / size	Flake · average 300 nm · BET 20 m²/g
pH / SG	6–8 · 1.2 ± 0.05 g/cm³
Dosage / packaging	1–2% · RoHS · 20 kg drum

Where the transparency matters

Clear protective coatingsWhere a UV absorber must not haze or yellow the film.

Transparent films and sheetsProtecting contents or the substrate itself from UV degradation.

Wood and outdoor clear finishesUV is what breaks down the coating and greys the timber underneath.

Antistatic transparent layersWhere a conductive black additive such as graphene would be unacceptable visually.

That last case is the useful contrast to draw. If your part can be black, a graphene dispersion gives a far stronger antistatic effect. If it must stay clear, zinc oxide is the route that does not cost you the appearance. Two different materials, chosen by whether transparency is negotiable.

What we do not claim

No UV protection factor, and no service-life figure. How long a coating resists UV depends on your resin, film thickness, total formulation and exposure. We publish the wavelength band the material attenuates; the performance of your coating is established by your weathering test.
No surface resistivity value. Antistatic behaviour in a finished film depends on loading and film formation. Establish it in trial.
Zinc oxide is photocatalytic. In some organic binder systems that is a durability consideration rather than a benefit, and it should be part of your evaluation rather than a surprise.
The manufacturer's datasheet is explicit that it is for reference only with no warranty of fitness. Test suitability first.

Questions buyers ask

Is this the same product you sell for sunscreen?

Yes, the same dispersion, TL-050901. In cosmetics it is a regulated UV filter and we make no SPF claim; in an industrial coating the regulatory position is entirely different. Tell us the application so we route the documentation correctly.

Will it stay transparent in my coating?

It is specified as a transparent dispersion with a flake morphology, which is what allows that. Final clarity still depends on your loading and dispersion, so trial it against your haze target.

Zinc oxide or graphene for antistatic?

Graphene is far more effective and is black. Zinc oxide is weaker and stays clear. The decision is whether transparency is negotiable.

What about photocatalytic degradation of my binder?

It is a real consideration with zinc oxide in organic systems. Raise it in your evaluation, and choose your binder accordingly.
