Some specific products are listed below.

Cho-bond 1035 PDF* is a one-part silver plated glass filled silicone RTV sealant used for bonding commercial conductive elastomers such as the Cho-Seal 1350 and Cho-Seal 1356, or for sealing joints. It does not require pressure during cure to produce a conductive joint.

Cho-bond 584-29 PDF* is a two-part conductive epoxy that has been used for the permanent bonding of metals and the repair of heating circuits. The filler is pure silver and the materials comes in small bi-packs know as Cho-packs. Cho-packs come in sizes as small as 1g up to 10g. The material can also be purchased in bulk.

Cho-Shield 610 PDF* is a two-part epoxy coating that can be used for the protection of steel, plastics and composites. It is a high performance silver plated copper filled material that was developed to meet the requirements of both military and high end commercial applications such as medical electronics.

Cho-Shield 2052 PDF* - Commercial grade silver plated copper filled acrylic coating designed for high-performance and adhesion to plastic substrates typical shielding levels of over 60db can be achieved. Compatible with plastics such as polycarbonate, pc-abs and pvc.

Cho-Shield 2054 PDF* - water-borne version of 2052

Cho-Shield 2056 PDF* - similar to 2052 but designed for high volume applications offering high performance with thinner a coating thickness resulting in reduced costs.
