New Product Announcement: Conformal Coating
Developer of innovative rapid and light-curable materials, dispense equipment and UV/LED light-curing systems, Dymax Corporation recently announced the release of a novel conformal coating.
Dual-cure 9771 was developed for use on printed circuit boards in missiles, satellites and spacecraft, the company says.
According to the company’s press release, Dual-cure 9771 meets NASA Low Outgassing Specification - ASTM E595 and Mil-Std 883 Method 5011. Mil-Std 883 method 5011 is a standard method for procedures to test electronic devices for military and aerospace electronic systems. The standard also includes mechanical and electrical tests to ensure quality and reliability suitable for intended end-uses that require low properties for ionic content, outgassing, conductivity and pH.
Additionally, the standard includes environmental testing to determine the resistance to the detrimental/harmful effects of natural elements and conditions surrounding military and space operations.
A first in the coatings industry, it is reported that no other conformal coating chemistry on the market currently possesses the certification.
The company goes on to report that Dual-cure 9771 is a reworkable coating that cures with light and moisture to ensure material that flows underneath components on PCBs fully cures. The new coating is also noted to have low ionic content, a UL 94 V0 flammability rating and is UL 746E recognized.
Other important features of 9771 include a resistance to corrosion, temperature and humidity, coating thickness to 0.008” (0.20 mm) and a bright blue fluorescing tracer that is highly visible on boards before and after cure for high-speed, inline quality inspection.
