About the model
E-Coating production process is unique and proprietary. Product mechanical structure is ideal for small-sized extruded strip applications. High conductivity and thin conductive layer create high level EMI shielding performance and good electrochemical stability; Lianxin uses specific primer coating process to ensure the surface coating is reliable in wear, corrosion and aesthetically appealing.
The inner core of E-Coating product is non-conductive elastomer. It retains good compression and rebound characteristics even in very small dimensions. E-coating elastomer is an excellent choice for environmental sealing and EMI shielding of small factor and compact structure design. Non-conductive elastomer cost is far less than the conductive elastomer, and only the product surface is plated with thin metal coating. This makes E-coating products very economical and competitive in the market.
Lianxin has introduced four series of E-coating products for selection: LIANXIN-SEALOR EC701: Silver/Glass, LIANXIN-SEALOR EC706: Silver/Nickle, LIANXIN-SEALOR EC707: Silver/Copper, and LIANXIN-SEALOR EC707D: Dark Silver. The differences amount these products are conductivity, EMI shielding effectiveness and electrochemical compatibility.
