DELO recently introduced a light- and humidity-curing sealant for connectors that are often found in vehicle control units or sensors. DELO DUALBOND GE4918 reportedly offers very good pin sealing properties, increases connector life, and allows efficient production.
Connectors need to be reliably sealed to protect electronics from humidity, media, and corrosion. Automotive suppliers generally use silver-coated connector pins since they are more cost efficient than gold and more reliable than copper. Silver is given an additional passivation layer to protect it from tarnish and abrasion. This coating is usually based on mercaptan and has been considered difficult to bond.
