Curtain spray

What’s curtain spray application?

Curtain spray

Patented technology

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.

The device enables uniform application over wide surfaces without creating joints and unevenness, which is difficult for conventional devices.
Thin application is also possible.

  • There are limitations according to the materials used.

 

A variety of application patterns can be selected by changing pattern shims.

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
  • HMA → Thermal fusion type
  • One-component adhesive → Normal temperature liquid
  • Water-soluble adhesive → Normal temperature liquid
  • Medicinal solutions
  • Water
  • Aroma chemicals
  • Soy sauce
  • Oil
  • Food oil
  • Chocolate
  • Curtain spray helps reduce the amount of liquid used, unlike conventional fan-shape spray which entails overspray.
