- Application Guidelines
AGCL-675 will thicken when it is stored in sealed containers over a period of time. It is essential to mix the material thoroughly before use to re-disperse any settled silver particles and to return the ink to a more desirable viscosity. Care should be taken to minimize material exposure to light. Yellow lights, screens or UV filters should be utilized above presses where material is being printed. Humidity needs to be kept to moderate levels, as moisture can also affect silver chloride over longer periods of time.
Screening
A monofilament polyester (180 to 260 mesh) screen is recommended, with emulsion thickness between .001" and .003". A polyurethane squeegee with a Shore ‘A’ durometer between 60 and 70 is recommended. All mixing blades, flood bars and spatulas must not have metal on the surface. Metals, especially aluminum, react aggressively with silver chloride. If metal flood bars and utensils are used, they must be wrapped completely with an inert tape, such as Teflon tape.
Cleanup
Use Solvent 10 or appropriate screen cleaner for cleaning screens. For other solvent recommendations, contact Applied Ink Solutions. If ink is to be left on an inactive press for any length of time, solvent evaporation can be minimized by pooling the ink into a small area instead of leaving it spread out over a large area. Pooling the ink reduces the surface area, thus slowing the drying process. Always check the viscosity of ink that has been recovered from a screen and add small amounts of solvent while mixing thoroughly to restore viscosity. Solvent can be added to reclaim thickened ink as long as the ink has not dried and hardened completely.
Drying
It is essential that all residual solvent be removed from this ink once it is applied. Incomplete drying will cause the ink to appear dry on the surface while trapping solvent underneath the surface. Over time, this trapped solvent will migrate out of the ink, and can cause adhesion problems with any material, such as dielectrics applied over the ink.
Completeness of Drying
Evaluate the point-to-point resistance along one of the conductive paths after one pass through the drying oven or one cycle in a batch-drying oven. Run the substrate through another drying cycle. Measure the point-to-point resistance again along the same path and compare it to the original reading. If the resistance decreases by less than 10%, then the ink is essentially dry after the first drying cycle or pass through the oven. If the resistance decreases by more than 10%, then more drying time is required to completely remove the solvent.
