Electrically Conductive Caulk and Sealant

All our electrically conductive caulks, sealants, pastes and compounds are formulated, manufactured and tested ‘in-house’ to create a fast and efficient turn around and to ensure a high quality product for our customers.

General description

Conductive caulks are electrically conductive composite materials generally comprising of silicone elastomer and conductive particles. They are designed to be easily applied to panel joints / seams and or the small clearances that result from non-continuous mechanical fixing in sheet metal enclosures. On application they cure at room temperature to form a highly conductive elastomeric section / joint that has good adhesion to most commonly used metals / substrates. When fully cured they help prevent water ingress and improve the EMI shielding performance of panel joints / overlaps.

Conductive caulks have excellent high temperature resistance and long-term ageing characteristics. The fillers used in these materials provide a reliable low impedance connection between suitably prepared metallic surfaces. The different fillers we can use help to ensure good galvanic compatibility with different alloys in wet or humid environments
