Conformal Coatings for Printed Wiring Boards and Electronic Devices

  • ULTRA HYDROPHOBIC
  • NON-HYGROSCOPIC
  • MOISTURE BLOCKING
  • UV-BLOCKING

Engineered molecular structure for proven performance in moisture penetration blocking, water repelling for salt-fog and water immersion protection of electronic circuit boards.

What distinguishes AIT’s Conformal Coatings are their unparalleled ability to adhere to all components on the printed circuit board (PCB) or printed wiring board (PWB) and induce zero stress while providing outstanding moisture, salt-fog and water barrier.  These capabilities are achieved with unconventional polymer engineering and designs.  AIT’s advanced conformal PCB or PWB protection products are ideal for large high performance devices operating at harsh ship board electronics and electrical contacts.

  • Moisture, salt-fog immune and immersion capable conformal coating for extreme reliability requirements
  • UV-blocking and moisture barrier microelectronic and electronic system coating for long-term usage under direct sun and rain exposure
  • RoHS, REACH and WEEE compliant to meet UL94V-0 rating

One of the proven applications of AIT SOLAR-BLOC™ protective coating is protecting large outdoor LED displays from color degradation and maintaining its brilliance for years.

All AIT Conformal Coatings and Masking Materials are RoHs Compliant

Automotive electronics require high performance conformal coatings to guard against humidity, water spray and condensation. Effective masking material solutions must be used to ensure cost effectiveness with easy application and removal.

Traditional acrylic-based and epoxy conformal coating that has glass transition temperature around 10-20°C and induces excessive stresses during low temperature cycles in the usages and reduces the reliability of the electronic devices (http://www.slideshare.net/CherylTulkoff/how-conformal-coating-can-kill).  AIT PRIMA-PROTECT™ CC7130-E is engineered to have glass transition temperature, Tg, at -55°C. That is, the PRIMA-PROTECT™ conformal coating is not sensitive to the thickness of coating applications and will not exert stresses on the components on the printed wiring boards.

The unparalleled performance and reliability demonstrated in the parallel side-by-side testings are attributable to the incorporation and combination of moisture penetration blocking and molecular flexibility to allow wide latitude of coating thickness to provide the best protection of electronic devices against heat and moisture, salt fog and even salt water immersion.
