What is slot-die coating?
Slot-die coating is a highly scalable technique for rapidly depositing thin and uniform films with minimal material waste and low operational costs. Slot-die coating technology is used to deposit a variety of liquid chemistries onto both rigid and flexible substrates. Rigid substrates include materials such as glass and silicon wafers, while flexible substrates include metal foils, polymer foils, and membranes. This is achieved by precisely metering the process fluid and dispensing it at a controlled rate while the coating die is moved relative to the substrate.
