Ensure Reliable Protection of Articles with Polyparaxylylene (PPX) Coating

PPX coating is a unique technique to provide reliability of articles, which operate in high humidity and temperature, or under influence of biological, chemical and other hazardous agents.

UNB-2 PPX coating equipment

Main specifications:

  • Max. article size: 200x420 mm
  • Coating thickness (optimal): 13-15 μm

PPX coating specifications:

  • Chemical inertness
  • Operating temperature range: - 100 to +150 °С
  • Radiation resistant
  • Mold resistant
  • Thickness uniformity
  • Perfect electric insulation
PPX coating features:
  • Continuity and uniformity of coating thickness over any kind of surface, including areas under electronic components
  • Brazing joints, leads, and etc.
  • No pin holes (micropores) in the coating, which is thicker than 5 μm
  • Low moisture and gas permeability
  • Chemical inertness to organic solvents, acids, and alkalis
  • High adhesion to various materials
  • Operating temperature: -100 to +1500 °С in air; -100 and to +400 °С in oxygen-free environment
  • Compatibility with materials used in electronic units, and with lacquering
  • Perfect electric insulation
  • Deposition of coating is performed under the normal temperatures, so delicate devices could not be damaged
  • Absence of internal stress, that may damage fragile component parts and thin conductors
  • Coating thickness up to dozens micrometers is deposited by one procedure
  • PPX coating has light weight as compared to other coatings or compounds
  • Radiation resistant
  • Low friction coefficient
  • No catalyst or other chemicals
  • Biocompatibility
  • Transparency (the signs on the components remain readable)
  • Solvent-free ecologically clean procedure of coating
  • Mold resistant
  • Easy to repair
  • Reliable protection of the connectors and non-sealed component parts
  • Regulation of coating thickness during the procedure of coating
