Fluorescent and Compact Fluorescent Lamps
These cements are designed to maintain the integrity of the bond between the glass and cap (typically metal or plastic) for the life of the lamp that can be between 3000hr and 30000hr. These cements contain a range of thermoset and thermoplastic materials in conjunction with specialised compounds designed to protect the adhesive bond from ingress of moisture or humidity.

These are used for tubular fluorescent and compact fluorescent lamps, the most widely used lamp in the world.
