Dual Cure (UV/Heat) DC Product Line

All our Dual Cure materials are one component materials. They are cured by either UV radiation, Heat, or acombination of both. This feature enables curing in partially or fully shaded regions of the device.The DC line includes both flexible and rigid products with a refractive index from 1.33 to 1.50, with relatively bigselection close to the index of silica. These include DC-1455 (flexible, index=1.448 at 950 nm) and DC-1455-HMand (Rigid, index=1.451) The DC line also includes high bond strength products like DC-150 (flexible) and DC-1473 (rigid).

The entry points of an optical fiber into the external package of a component can be sealed using one of our Dual Cured products, such as DC-1455 (when important to keep the index just below that of the silica fiber core) or DC-150.

Both are very flexible, and this reduces the stress during thermal cycling or after a thermal shock. This enables the higher reliability of the device. The Dual Curing feature can be used for an initial fixing of the external side of the seal. Afterward, heat curing is used to cure the hidden part of the seal.
