Conductive pastes consist of conductive fillers( Au, Ag, Ni, Cu etc.), organic binders, solvents and additives. Meanwhile, there are some metal powders such as copper, nickel etc that are used for pastes which have serious surface corrosion problems. This problem leads to change of the color and decrease in conductivity and affect storage stability of conductive pastes. By using silane coupling agent and dispersion agent, we can ensure both the corrosion stability and long term storage stability, and enhance the high performance electrical and mechanical properties of EMI shielding silicone sealant.

대상 데이터
Silver coated copper made in changsung corporation, Korea. Dispersing agents were supplied by BYK (Germany), Kusumoto chemicals (Japan), and EFKA (Germany). Silane coupling agents were supplied by Shin-Etsu chemical (Japan), Dow corining (USA), and Chisso (Japan).
성능/효과
Based on these results, it is concluded that corrosion stability can be achieved and the electrical and mechanical properties of EMI silicone sealant can be enhances by silane coupling and well dispersing .
