Wet Processing Center

Precision Wet Processing for Roll-to-Roll Foil

The Wet Processing Center enables accurate roll-to-roll handling of foil in a fully enclosed, safe environment. Designed for research, prototyping, and pilot production, it supports immersion, spraying, and electrochemical treatments for thin-film technologies, printed electronics, solar cells, and other advanced materials.

Immersion and Spray Processes

The system allows full liquid immersion for etching, washing, coagulation, imbibition, and ion or solvent exchange. Spray treatments apply liquids across foil surfaces while washings are recovered or safely discarded, offering controlled and efficient processing.

Electrochemical Treatments

Built-in electrochemical functionality provides heating, cooling, and agitation, while foils can be electrically connected with counter electrodes for various surface treatments.

Handles Extensive Chemistry 

• All Non-Oxidizing Acids

• All Bases

• Glcohols

• Gliphatic Hydrocarbons

• Vegetable and Animal Oils

• Biological Agents

• Aqueous Salt and Detergent Solutions

Modular and Scalable Design

Processing tanks can be linked for sequential treatments such as etching, developing, stripping, and washing. Configurations include direct docking with the Laboratory Roll-to-Roll Coater (10 L) or stand-alone systems (50 L). Processing lengths range from centimeters to five meters, and a variety of rollers supports integration with ovens, coaters, knives, and laminators.

Safe, Clean, and Durable Operation

Closed-system operation ensures zero solvent or liquid emissions. Double-sided air knives enable rapid drying, and high-quality plastics, ceramics, and stainless steel (316L) ensure long-lasting chemical resistance.

Integration with the Laboratory Roll-to-Roll Coater

Designed to integrate seamlessly with the Laboratory Roll-to-Roll Coater, the Wet Processing Center provides a compact, versatile solution for lab and pilot-scale thin-film applications. Modular components allow customization for batteries, medtech, fuel cells, printed solar cells, sensors, and more, enabling optimized performance with flexibility and scalability.
