Functional Pastes

Different Thinking to Move Forward, Functional Pastes

Chang Sung’s conductive pastes are advanced eco-friendly materials that are widely used in innovative precision industries, such as future-oriented IT devices, industrial devices, and automotive electrical and electronic components. Propelled by the advantages of trust and high efficiency, CSC conductive pastes realize the dream of high-tech materials envisaging the Nth industrial revolution.

Functional pastes are composite materials with high flowability in which functional fillers, binders, and solvents are uniformly distributed. Metallic, ceramic, or carbon materials are selected as functional fillers depending on what the paste is used for. Glass frits or polymer resins are used as binders according to the substrate type and heat treatment temperature. The workability of the paste is determined based on the applied processes, which affect its fluid properties, such as printing, dipping, and dispensing.
