Slit-nozzle Coater for High Viscosity Liquids
Most suitable for coating of high-viscosity functional materials
Toray Engineering’s high-viscosity liquid coater has specially been developed by bringing together its own elemental technology: slit-nozzle, high-precision pump, high-precision stage, and reduced-pressure heating dryer. This coater is suitable for coating high-viscosity pasty-functional-material such as polyimide varnish for flexible display as well as solvent-less high-viscosity material such as adhesion and ultraviolet curing resin.
With our reduced-pressure heating dryer for high-boiling polyimide and hot oven, Toray Engineering is ready to produce samples for our customers.
High performance slit nozzles with unique fluid analysis / low pressure loss design are installed, and our high precision discharge pump and precision coating control realize high film thickness accuracy and productivity.
Available to coating highly viscous liquids in a wide range of fields including polyimide liquid, UV curable resin, adhesive, various functional materials.
