Ultraviolet Curing Adhesive Systems
Hernon offers a complete line of ultraviolet curing
adhesives and compounds, the Ultrabond line of products. These
products are single component systems offering either ultraviolet
light or ultraviolet light & primer initiated curing mechanisms.
All Ultrabond products cure upon exposure to UV radiation. Twin
or "dual-cure" types, working in conjunction with Primer,
provide production processing latitudes to maximize assembly
efficiencies.
Dedicated UV cure types, or "UV cure only"
grades cure when exposed to UV light. All Ultrabond adhesives
respond to exposure to high intensity medium pressure mercury
arc UV lamps in the range of 365 nm (long wavelength) and 100
milliwatt per square centimeter intensity. Some Ultrabond systems
function well with low intensity lamps, such as "black lights."
Cure speeds are longer and gap fill ability is lower under these
conditions.
Twin or dual-cure systems offer choice of UV and/or
Primer to initiate curing. Use Primers to fully cure the adhesives
anaerobically or to obtain fixturing strength prior to final
full UV curing. Primers also Promote deeper cures.
