Silver Metal Ink, Conductive Water-Based Coating, 6 gram 33% Ag Brush-Cap Bottle
This Silver Metal Ink is a low viscosity, medium solids, silver-filled ink. Typical applications include RFID tags, cell phone antennas, EMI/RFI Shielding, PCB prototyping, medical EEG/EKG sensors. It is also suitable for any application requiring a hard, durable and highly flexible and conductive film and it can be sprayed or brushed onto your substrate. The conductivity is especially prevalent  in very thin traces down to 5 to 6 um dried thickness.Not only is this ink designed to dry very quickly, but it has excellent adhesion to a wide variety of substrates. However, due to the higher water concentration of this formulation, it is recommended that you choose the 66% silver product if you will be a coating low surface tension material, such as plastic or glass.Non-hazardous and ships anywhere with no restrictions. 6 month shelf life.After application, oven drying is recommended. Depending on the film thickness, drying can be accomplished in less than two minutes at temperatures above 250F with adequate air flow. Completeness of drying can be verified by measuring the electrical surface resistivity of dried material using a box electrode or point electrodes hooked up to a multimeter. After initial drying, measure surface resistivity. Dry the material for another cycle and measure resistivity once more. If the drop in resistivity between the first and second drying cycle is less than 10%, drying can be considered complete after the first cycle. For more critical applications or where outgassing may be a concern the difference in resistivity between the two drying cycles should be less than 5%, and consideration should be given to post-baking the material in batch ovens for 30 to 60 minutes at 250 - 300F.If oven drying is not appropriate for the substrate being coated, it may take several hours for the ink to dry, depending on coating thickness. Again, check the resistivity using the process above to verify that the ink has fully cured.
