This coating method was called select coat which was developed by Takaji Shimada 30 years ago. When we applied for a patent on this, we called it Shimada application or film coat at first. T Shimada developed this in working without pay and skunk work after he finished a daily business activity. In now 30 years after it, the representative of Shimada Appli G.K. developed a new film coating valve again and acquired a patent.
Shimada Appli's SA film coat system has a good response speed by pass point control even in high speed conformal coating, so productivity is significantly improved compared to other film valves. The photo shows a coating time of 21 seconds.
FS Type Micro Spray Gun with Leaf Nozzle is sent to the world!! The leaf nozzle sprays in high-speed self-oscillating operation of per second 10 cycles or more.
This is an electrostatic spray gun for thin film formation that enables uniform coating with fine particles by equipping the high-performance FS micro spray valve with electrostatic application. -Overview- Two types of electrostatic micro-spray are available, one for forming thin films of low-viscosity materials and the other for forming thin films of medium-to-high-viscosity liquid materials to several tens of micrometers. -feature- Thin coating from 350 angstrom is possible・Reduced amount of coating liquid used・It is possible to coat three-dimensionally complicated shapes.・Good edge coverage・The atomization performance is improved and the drying rate is increased. -Main use- Selective thin film coating of functional liquid materials・ Nano-order coating of conductive materials such as PEDOT・Partial application of resist material, etc.・Thin wire application of various materials, etc. A high voltage of -5 to 30 kV is applied to the needle at the tip of the gun from a high-voltage generator using a corona charging system, and corona discharge ( corona-charging) occurs, creating an electric field between the object and the object to be coated, and the particles that pass through this electric field are charged and attached to the object to be coated. Fine particles cannot coat substrates only by their inertial force. The micro electrostatic force application spray makes it possible to adsorb fine particles that are difficult to adhere to the substrate by applying electrostatic force. Coating with the power of electrons has the property of concentrating the electric field on the edge, so it can be said that the coverage is good. Due to these features, it is possible to form films on substrates with complex shapes that cannot be coated by spin coating. The micro-electrostatic spray for forming a film of several tens of μm with medium- and high-viscosity coating materials electrostatically applies fine particles misted by a screw extension or a star-shaped air cap to finely atomize viscous materials. Electrostatic application by charging in the corona charging area.
To create a thin coating pattern with clear edges, the left-rotating atomizing air and the right-rotating air cover promote high atomization and create a directional swirling atomization flow.

When applying Elepcoat (model LSS 540 MHF) manufactured by Nitto Shinko Corp. which is a solvent-containing moisture proof insulating material, angel hair occurs unless weight ratio is 1: 1 in order to counteract angel hair with air spray or airless spray. (External division 100% weight ratio dilution) By using this spray coating device, the following good results were born. Coating application results Coating material: Conformal coating material Elepcoat type model LSS 520 MHF (manufactured by Nitto Shinko Co., Ltd.) Undiluted solution 400CPS Solids content 15-35%

The new nozzle enables formation of a liquid film coating pattern of 200-1000CPS viscosity conformal coating materials！
Overview:
Conformal coating materials with a viscosity of 200 to ３000 centipoise＊ can be applied at high speed by using a new nozzle (patent pending) and selective coating that forms a liquid film coating pattern.
As a result, it is possible to coat solvent-free silicone, UV-based materials, etc. at a coating speed that is more than double that of conventional two-fluid sprays.
