TYPICAL PROPERTIES OF UNCURED MATERIAL Solids Content by Weight, % 73.7 Percent Silver, % 65 Viscosity, Brookfield - RVT, 25 °C, mPa·s (cP): Spindle 6, speed 20 rpm 14,000 Density, kg/l 2.5 Shelf Life @ 32 °C (from date of qualification in original seal), days 90 Flash Point , Tag Closed Cup Flash Tester, oC 99 TYPICAL SCREEN PRINTING PROCESS This product is applied by standard screen printing techniques. The dried film thickness and final resistance is influenced by a number of factors, including screen mesh size, squeegee material, screen material, and emulsion thickness. Recommended Thickness, dried, μm 8 to 13 Emulsion Thickness , Solvent resistant emulsion , μm 20 to 38 Screen Type Monofilament polyester screen, mesh 157 to 280 Stainless steel screen, mesh 165 to 325 : Monofilament polyester screen, mesh 157 to 280 Stainless steel screen, mesh 165 to 325 Squeegee (polyurethane or other solvent resistant material): For use on Polyester screens, durometer 60 to 70 For use on Stainless steel screens, durometer 70 to 80 TYPICAL CURING PERFORMANCE LOCTITE EDAG 477SS E&C can be cured at 200°F (93°C) and up. The higher the temperature, the lower the final resistance will be. Increasing the temperature will also reduce the time needed to achieve a final cure. For example, at 200°F (93°C) cure for 15 minutes; at 250°F (121°C) cure for 5 minutes. Percent Volatiles VOC, g/l 670 The above cure profile is a guideline recommendation. Cure conditions (time and temperature) may vary based on customers' experience and their application requirements, as well as customer curing equipment, oven loading and actual oven temperatures.
