DIRECTIONS FOR USE

Mixing and dilution

ECP 505 is easily mixed by stirring and care must be taken to ensure all solids are evenly dispersed. Dilution is not usually necessary. Product can be thinned with Xylene based thinners if necessary. ECP JSF024 thinners may be used.

Application method

Conventional propeller agitated pressure pot systems can be used for production. Small sample runs can be sprayed using suction cup spray equipment providing product has been well mixed and is not given time to settle in use. Highest efficiency has been achieved using high volume, low pressure (HVLP) spray guns.

A nominal 25-50 *m coating thickness is recommended for good shielding properties. A thinner coat can be used depending upon the shielding requirements of the device being protected. Avoid dry spray for maximum adhesion and conductivity.

Drying

Ambient temperature and film thickness affect drying. ECP 505 EMI Shielding SIlver Plated Copper Paint is touch dry in approx. 5 minutes and to handle in about 10 minutes. Best results will be seen 4 to 16 hour's air drying It can be force dried for 20 minutes at 60*C after a short flash off time.

Quality Control

Measure the surface resistance after coating is fully dried. Resistance measurements using fixed test probe rigs ensure reproducibility, although point to point readings are also frequently used. The use of point probes is not advisable due to contact resistance issues and probes should be of sufficient surface area to ensure good electrical contact with the substrate

Cleaning

Masks can be easily cleaned with solvent.
