| Organic Ingredients including resin, solvents and additives in silver slurry for membrane switches play very important role as they will not only directly affect the performance of the product but also have great impact on the environment. In the present work, different kinds of resin, solvents and additives were tested for their usability as organic ingredients in production of the silver slurry. By comparison, an organic system consisting of the thermoplastic polyester resin as the main body, a MEA mixed solvent, YU-201 silane coupling agent and a reinforced plastic material M-17 as the additive was selected as it had great usability. The silver slurry produced in this organic system displayed superior performance in membrane switches. Moreover, and it is free from halogen, conforming to the requirements of EU Standard RoHS |
