Nickel graphite filled conductive, 1-component sealing

Shieldoseal 3991 series creates a electrically and thermally conductive connection between components. Used for ESD and EMI shielding applications.

Shieldoseal is a 65-durometer adhesive sealant, filled with electrically conductive particles. The sealant will cure within 24 hours, but ultimate physical properties could take up to 72 hours to develop. Shieldoseal should adhere excellently to most substrates


Shieldoseal for EMI shielding

One of the applications of Shieldoseal is EMI shielding. Shieldoseal has excellent filling properties, therefore almost any surface can be filled up. Shieldoseal cures quickly at room temperature. When fully cured, the substance remains as elastic as rubber and is homogenously conductive. In addition, it especially distinguishes itself from other substances by a high level of heat conductivity. Shieldoseal is pasty and can be used to glue metals (copper, aluminium, stainless steel, brass, etc.), ceramics and most plastics. Properties for individual applications are listed in the table below.
