acheson Aiqi Sen Silver Electrodag 725A (6S-61) is a specially designed membrane switches and flexible printed circuit of the efficient conductive silver paste. 
 ED 725A Product Description: 
 The screen printing is the printing of conductive silver paste of highly reliable touch membrane keyboard of choice, dry after printing, it is also able to adapt to different temperatures and achieve the purpose of fully dried, it makes the users in the construction of greater flexibility, this paste is the result of a special recipe and make it also has very good bending resistance, on the various substrates, either through the ink adhesion strengthening Pat dealt with, or is not treated, has very good adhesion. 
 Advantages: 
 * Low resistance (ie high conductivity) 
 * Excellent deflection of 
 * Excellent adhesion 
 * Good printability 
 * No dilution 
 * In the wire-line to maintain the durability of that can be printed 
 * Use simple 
 * Can not prolonged cold preservation (storage below 25 ℃) 
 Nature (the original tank to time): 
 Conductive material: Silver 
 Color: Silver 
 Viscosity: 17, (cps) 
 Solid components: about 61% 
 Density: kg / liter 
 Best storage period: the original tank storage, the best storage period of up to 12 months 
 Flash point: 212 (100 ℃) 
 VOC (volatile organic substances): 824 g / liter (lb / gal) 
 Can cover an area of theory: If the ink film thickness of 25um (ie 1mil), 
 Square meters. (That is 489 square feet / gallon / mil) 
 After the performance of dry solid (silver line printing, the use of 121 ℃ bake 5 minutes): 
 Conductivity: <0.017 ohms / square @ 1 mil (dry film thickness of the silver line is 25um () time.) 
 Deflection of: 5 Inflectional (inflectional words repeated till the printed circuit resistor when the number rose fifty hundredths). 
 Adhesion (tape test): After tape test, the silver line resistance increases less than 5%. 
 Pencil Hardness: 2H
