Typical Installation & Usage Scenario
-
Clean the substrate (for example, an ABS panel) with isopropyl alcohol to remove oils and contaminants.
-
Shake the aerosol can vigorously for at least two minutes to ensure pigment dispersion.
-
Hold the can 20–30 cm from the surface and apply light, even coats.
-
Allow a minimum of three minutes between coats; build up thickness with successive passes.
-
After the final coat, permit 24 hours for a full cure before handling or grounding connections.
This process yields a uniform conductive layer ideal for shielding electronics enclosures, grounding contact points on test fixtures, lining guitar pickup cavities, or reinforcing metal-detector housings without adding excessive weight.
