Adhesive that is cured after a certain period of time of light irradiation,thus allowing for UV adhesion of light-shielding parts.

Allows UV adhesion of light-shielding substrate

Example 1: Traditional UV curing resin

Example 2: Comparison between traditional resin and Sekisui's resin

 

Rapid curing is produced by heating after UV irradiation (heat-resistant curing adhesive; see the figure below)

A combined process of UV curing and thermal curing reduces the curing time of resin to not more than 1/10 of that for traditional thermal curing epoxy resin.

The transparency, viscosity, and usable time (time until curing starts) are adjustable.
