Silver-filled adhesives withstand harsh conditions

Master Bond Inc. has introduced Polymer System AC85, a highly conductive, silver-filled adhesive and sealant. Due to its non-oxidizing silver particles, the AC85 promises high conductivity. It also features long-term durability, even when exposed to harsh environmental conditions, due to its oxidation- and chemical-resistant properties.

The AC85 is considered to be cost effective, combining easy application with high area coverage. Performance characteristics include a service temperature range of -62°C to 150°C, a surface resistance of 0.03 ohms/square, efficient ESD performance and an EMI performance of 60-70dB.

Master Bond AC85 is easy to apply as it is a solvent-based, one-component system with no need for catalysts or accelerator additions. Application is by brushing, dipping, air and airless spraying equipment and silk screening. Viscosity can be readily adjusted with compatible solvents such as toluene, xylene and methylene chloride.
