Silver Conductive Epoxy Adhesives Description
Silver-based conductive epoxy adhesives are adhesives that exhibit a measurable level of electrical conductivity after curing or drying. They can bond various conductive materials, thereby establishing an electrical path between the joined components. In the electronics industry, the conductive adhesive is regarded as an important new material.
