ECP 555 SIlver Plated Copper EMI Shielding Aerosol Paint

 ECP 555 silver/copper aerosol combines the EMI Shielding properties with a convenient method of application for prototype and touch up work. It is designed to give low resistance in thin film thickness displaying excellent adhesion to most plastics it is ideal for electronic equipment housing. It exhibits excellent long term shielding and grounding properties whilst providing an aesthetically pleasing appearance.

Physical Properties

• Surface resistance at 25 micron (thou) ASTM D257 0.7 ohm/sq or less
• Pigment - silver plated copper
• Flash point -5⁰C
• Typical coverage approx. 6 square feet

Typical Properties

• Sheet resistance <0.1Ω/square at 25 μm
• Attenuation 75dB at 50 μm
• Maximum service temperature 95⁰C

Directions for Use

Surface Preparation - all contaminants including mould release, grease and dirt must be removed.  Mask areas that do not require spraying.

Mixing - shake vigorously for a minimum of 2 minutes to evenly distribute contents.  Spray a small area to check compatibility with substrate.

Application - operate in an upright position, spraying in light, even strokes from side to side to avoid flooding.  Shake briefly at intervals during spraying.  On completion, invert the aerosol and spray to clear valve and nozzle.  It is advised to clear any excess material from the nozzle at frequent intervals to prevent blockage.  If the nozzle blocks, use a pin to clear the opening, or remove the nozzle and flush with toluene, xylene or MIK.  Replace the nozzle taking care to point the opening away from you.

Precautions

Pressurised container.  Protect from sunlight and do not expose to temperature exceeding 50⁰C.  Do not pierce or burn, even after use.  Do not spray on an open flame or any incandescent material.  Keep away from sources of ignition.  No smoking.  Consult health and safety data before use.

Drying

ECP 555 is touch dry in approximately 5 minutes and to handle in about 10 minutes depending on ambient temperature and film thickness.  Best results will be seen 4 to 16 hours air drying (dependent upon film thickness and ambient temperature).  It can be force dried for 20 minutes at 60⁰C after a short flash off time.

Quality Control

Measure the surface resistance after coating is fully dried.  Digital ohm meter measurements using the same type of fixed test probe rigs avoids confusion and is highly recommended, although corner to corner readings are also frequently used.

Cleaning

Masks can be easily cleaned with solvent.  Over spray can be removed from plastics with 40/60% acetone/IPA wipe.
