FAQ & Contact

Due to the large amount of interest, we are unable to address individual questions from prospective customers. We cannot provide information as to whether our products will serve for the purpose you want because we sell our product as is.

I have a large business, hospital, airline, event space and I want this. Do you accept large orders?

You can place an order of any size on our website. We can rapidly scale to any quantity needed, anywhere in the world, though large orders will take 6-8 weeks to fulfill. Contact michael@getchroma.co if you have questions about this.

What does the finish look like?

All CopperCoater paints leave a matte black finish. Unlike regular metallic spray paints that look glossy, even our standard version has a higher copper loading that prevents this appearance from being possible.

How durable is it?

CopperCoater is expected to last at least 1 year based on studies showing no loss in efficacy of copper compounds after 90 days. Due to the high volume of powder, it can be scratched with a fingernail, but will otherwise adhere firmly.

Are nanoparticles dangerous?

When they are in the air, yes, since they are respirable. Nanoparticles are safe once they are on a surface inside a binder.

Is long term copper toxicity a risk?

Researchers we have spoken with believe the risk is low, but it's not impossible. No long term studies have been conducted with our product. If this concerns you, please do not purchase this product.

Is it copper or a copper oxide?

Elemental copper. Safer, more effective, and more aesthetically pleasing than the copper oxides used in maritime applications for anti-fouling.

Why is the color black?

We include iron oxide, which has the dual purpose of ensuring consistent black color and working synergistically with the copper.

How long will it last?

As long as any other spray paint. You may want to re-coat surfaces yearly as the ion-release rate may decrease over time. Additional data on this will be made available as soon as we have it.

Have you tested this coating with COVID19 or a representative virus that would have a similar response?

We are working with biologists toward getting this data and will update with more information as soon as it is available.

Is it really nanoscale?

Our founding team includes materials engineers that were quite reluctant to use the term "nano" since we like the definition that the material must be no more than 100 nanometers in any particular direction. While some of the copper will meet that definition because the particle sizes follow a distribution, most of them do not. 1000 nanometers is a micron, and all the copper is smaller than that in order to spray well and form a smooth coat. Consumer products often use the definition of under 1 micron to mean nano. We'll let you be the judge. The iron oxide on the other hand is a bonafide nanomaterial any way you look at it.
