What’s curtain spray application?
Patented technology
A device that performs spray application by making HMA into fibrous form.
The device forms a non-woven fabric-like surface uniformly by making use of the cohesive property (viscosity) of HMA to spray fine fibers, allowing the whole spray application on a wide area.
For other liquids (medicinal solutions, aroma chemicals, oil), the device microparticulates and atomizes them to perform application.
The device enables uniform application over wide surfaces without creating joints and unevenness, which is difficult for conventional devices.
Thin application is also possible.

Application of curtain spray
Curtain spray technology was originally developed as a method for HMA.
The excellent technology is now used in various fields.
- Horizontal application
- Lamination
- Powder mix, solidified
- Base materials with corrugated surface
Adhesive
- HMA → Thermal fusion type
- One-component adhesive → Normal temperature liquid
- Water-soluble adhesive → Normal temperature liquid
General liquid
- Medicinal solutions
- Water
- Aroma chemicals
- Soy sauce
- Oil
Food
- Food oil
- Chocolate
- Curtain spray helps reduce the amount of liquid used, unlike conventional fan-shape spray which entails overspray.
