Spray Coating of Carbon-based Nanomaterials

My client application involves spray coating of carbon-based nanomaterials (e.g. graphene, carbon nanotube) on the metal surface. They need a Ultrasonic Nozzle that is: between 60-130khz, can go as small as 3mm*3mm spray area, programmable. If you need a ultrasonic nozzle, we would love to have a call with you.
