FirmWIPE® is constructed from an open-cell ester-based polyurethane foam which has undergone a special felting process.

• Open-cell polyurethane structure allows for fiber-free wiping
• Excellent pick-up of Thick Film inks and solder paste
• Open-cell, felted foam structure allows for controlled transfer of solvent to optimize cleaning of Thick Film screens
• Ester-based chemistry and felted construction enable broad solvent compatibility
• Uniform porosity allows for excellent contamination pickup

FirmWIPE® wipes provides fiber-free wiping in applications where durability and fast wicking, without dripping, are desirable. Due to its ability to conform to metal mask surfaces, wipe enables excess paste to be thoroughly removed while minimizing abrasion to the emulsion. Its unique pore structure makes it ideal for cleaning metal masks used to print LTCC components, capacitors, EL, OLED, and Plasma Display Panels.
