Dymax‘s 9771 light-curable, conformal coating for use on critical PCBs in satellites, spacecraft and missiles has received a prestigious NASA MAPTIS (Materials and Processes Technical Information System) material number — 09841.
As a result, 9771 is now recorded in the approved materials database used by NASA and suppliers. The importance of this listing is that NASA has independently verified the coating to meet ASTM E595 and allows people looking for low outgassing materials to find the product more easily.
NASA low outgassing ASTM E595 test method is a screening procedure to determine the volatile content of materials when exposed to a vacuum environment. The test is run at 125°C (257°F) under a 5 X 10-5 Torr vacuum for 24 hours. The Total Mass Loss (TML %) and Collected Condensable Volatile Material (CVCM %) are measured. CVCM is of particular interest as it might be indicative of loss of electrical continuity, or some other effect caused by material being deposited where it is not intended.
In conjunction with the NASA material number, dispense guidelines have been established to ensure that a consistent coating thickness of 50.8-101.6µm (0.002-0.004”) is achieved. Dymax recommends applying the conformal coating using a PVA Delta 6 Selective Coating/Dispense System with FCS300 series valve.
The Dymax team of Applications Engineers are available to customers through every step of their project to ensure successful outcomes.
9771 is a reworkable conformal coating that cures with light and moisture to ensure material that flows underneath components on PCBs fully cures. The product has low ionic content compliance with MIL Std 883 Method 5011, UL 94 V0 flammability rating, and is UL 746E recognized.
Additionally, Dymax has purchased a building in Monroe, North Carolina, that will be customized and built out with new equipment over the next few years. The Monroe Corporate Center is a Class A precision manufacturing industrial park which is home to many international and innovative companies.
Dymax will expand from its Northeast roots as the company continues to experience increased demand from an expanding global customer base. Located just outside of Charlotte, the region opens doors to outstanding labor, technical and logistical resources. The new manufacturing facility will consist of several functional areas including raw material warehouse, manufacturing, finished product warehouse, multiple labs, and office space.
