Ultrasonic nozzle and rotator module. For coating tubular substrates .
The software module is easy to use with sliders and numeric controls setting process parameters, such as length of tube, portion of tube to be coated, speed, flow rate and distance. Settings are easily saved and restored for recurring setups.
The ultrasonic nozzle provides small uniform drops that results in thin homogenous layers.The module is fully equipped with pump with changeable syringe in different sizes. The short distance from the syringe to the nozzle reduces the waste. The module lets you adjust the nozzle 180 degrees.
Applications
Fuel cells
Membranes
Gass separation
​
Transparent conductive film
​
​Photoresist on MEMs wafer
​Protective coatings, etc
More on Spray Coating
Spraying is ever present in our lives, and has been used for ages for a number of purposes, including applying decorative and protective coatings. Thus it is another tool available to a Material Scientist for thin film preparation.
In spray coating, the nozzle dimension, the spray shape, nozzle to substrate distance, spray velocity and application of heat to the substrate during spraying are parameters that can be controlled for optimum result. These are accomplished easily in the MultiCoater, and more.
Pressure nozzles were initially used in spray coating. They have the set back of requiring slightly complex system (for pressure generation), high material wastage and environmental pollution, especially dangerous for the personnel doing the spraying.
With ultrasonic nozzle, the spray solution is homogenised, drop size effectively controlled (nozzle frequency influences drop size), and micro spray volumes can be dispensed, ensuring uniformity in composition and structure and more precision of the resultant thin films and patterns. Material wastage is kept to a minimum and there is less risk to the operator of the equipment.
The MultiCoater’s ultrasonic spray coating can be equipped with a heated platform for the substrate. It is the ideal platform for simple and cost effective transformation of your nano and micro materials into functional thin films.
