Flame resistant Dymax 9771

Flame resistant

Very low outgassing

Cleaner PCB assemblies are achieved during extreme conditions thanks to ASTM E595 certification for outgassing.

Low ionic content

Dymax 9771 passes Mil-Std 883 tests for thermal stability and filler content via thermogravimetric analysis, specific ion content, total ionic content, hydrogen ion content (pH), and volume resistivity.

High-density boards? No problem

Cureable with UV light, 9771 also features a secondary moisture cure mechanism to ensure all material, including any that flows underneath components on a PCB, fully cures.

One of a kind coating

Military and defence product manufacturers finally have a conformal coating which meets both the required standards ASTM E595 & MIL-STD 883 and appears on NASA’s MAPTIS register of approved materials.
