  • High density construction and sponge-like properties make it ideal for particle sensitive metal mask cleaning operations
  • Open-cell, soft foam structure allows for controlled transfer of solvent to optimize cleaning of thick film applications
  • Excellent abrasion resistance and fluid retention enables fiber-free wiping of thick film screens and hot molds
  • Will not interfere with the curing of elastomeres, platinum cured silicones or adhesives
  • Allows for thorough removal of solder paste from stencil face and aperture
  • Uniform application of solvent to achieve "kill" ratios on aseptic surfaces
  • Excellent abrasion resistance to reduce particle generation in-use
  • Static dissipative to minimize the risk of ESD events
  • Pyrogene-free for medical device wipe-down
  • 100% fiber-free
UltraSORB® is a highly absorbent wiper that combines excellent ESD characteristics with class 100 cleanliness. Due to its sponge-like wiping capability, fiber-free construction and ability to resist shedding of particles due to abrasion, it is the perfect choice for stencil, thick film screen and medical device wiping applications. It's unique pore structure allows for controlled solvent transfer to screen and metal masks to aid in the removal of solder paste, conductive adhesives and thick film inks. Ideal for cleaning metal masks used to print LTCC components, capacitors, EL, OLED and plasma display panels. Due to its ability to conform to metal mask surfaces, UltraSORB enables excess paste to be thoroughly removed while minimizing abrasion to the emulsion.

APPLICATION: Cleaning movement in one direction, no circular movement!
