Curtain spray

What’s curtain spray application?

Curtain spray

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
    水平塗布
  • Lamination
    貼り合わせ
  • Powder mix, solidified
    粉体混合、固着
  • Base materials with corrugated surface
    凸凹面基材

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.
