Technology with High Transfer Efficiency and Superior Coating Quality

Coating Technology

We believe it is our mission as a coating equipment manufacturer to develop technology under such keywords such as "striving for 100% transfer efficiency," and the underlying or fundamental technologies like "atomization," "volumetric feeding" and "eco-friendly paint," and we continue to meet the challenges that confront us each day.

Volumetric Feeding Technology

"Volumetric feeding technology" is required to provide a stable supply of paint in order to create high transfer efficiency and superior coating quality. At Asahi Sunac, by combining our own developed software and superior high precision processing technology, used at our factories and plants, we can recommend the best supply system for your application, from standard pumps to "high viscosity paints," "high volume discharge" and "high accuracy."

Eco-Friendly Paint Technology

Paints containing organic solvents are often used in coating applications. However, recently given the trends toward environmental preservation on a global scale, paints that contribute to reducing VOC (volatile organic compounds) and CO2 emissions are receiving more attention. At Asahi Sunac, we are involved in technology development that can use these types of paints for high level coating.

Two-Component Coating

By mixing a stable, consistent supply of "hardening agents" using urethane and epoxy coating, we can reduce the CO2 emitted from the drying kiln by creating a coating film using controlled temperature drying and low temperature baking. In addition, because coating films have good weather resistance, they are also often used in resin coating, which cannot be baked in construction machinery and at high temperatures.

Power Coating

This coating method creates a coating film by charging the particles in the powder paint using an electrical charge to improve efficiency, spraying it onto the target and then heating up or fusing it to the target. Since there are no organic solvents in the ingredients for the paint, there are almost no VOC emissions, and the powder paint can be collected and recycled, thereby contributing to a reduction in costs and preserving the environment.

Water-Based Coating

Compared to solvent based paints, we can reduce the VOC emissions significantly. This type of coating is often used in the automotive industry as well as many other industries. Recently, new water-based coating, which combines hardening agents and water-based paints, is also being developed and is used to coat internal automotive components, etc.

Coating Without Solvents

Used for two component paints that are able to form a film solely through chemical reactions which are mainly used for anti-rust purposes in shipbuilding, levee protection works, and internal coatings for steel water and sewer pipes. Paint is supplied using an ultra-high pressure transfer pump and application of the coating occurs via a two component airless pump.
