Techma 3

• Tests with minimal material quantities
• Thermal drying/curing
• Substrate speed: 0.1 – 100 m/min
• Substrate width: ≤500 mm

Techma 3 is a narrowband system for tests with minimal quantities of liquid. It enables coating at very low substrate speeds. The coated films are hardened using hot air. The dryer comprises six zones, each 1.5 meters long, which can all be used as both support roll and flotation dryers. The blow-out speed and temperature of the air can be set over a broad range in each zone. The winders operate in stop-and-go mode. Upstream of the coating station, the substrate can be tensioned, cleaned and pretreated with Corona.

The following methods are available for coating: 

• Slot dye with vacuum chamber 
• Gravure roll in direct or indirect configuration and forward or reverse operating mode
• Smooth rollers in dual, triple or quadruple arrangement and forward or reverse operating mode 

Downstream of the dryer, further options include dry lamination and substrate cooling.
