Device for pre-activating and dosing an actinically curable compound and use of the device

Abstract

A device (10) for preactivating and dosing an actinically curable compound, in particular a polymerizable compound, is specified, comprising a dosing unit (12) for adjusting a volume flow of the curable compound, a channel (14) for guiding the curable compound to an outlet nozzle (16), and an irradiation unit (22) which emits actinic radiation for preactivating the actinically curable compound, wherein the channel (14) is radiotransparent to the actinic radiation of the irradiation unit (22) at least in a window section (15), wherein the irradiation unit (22) is assigned to the radiotransparent window section (15) of the channel (14), and wherein the device (10) has a sleeve (20) which is also at least partially made of a radiotransparent material to the actinic radiation and surrounds the channel (14) at least in the area to which the irradiation unit (22) is assigned, and wherein the device (10) has a thermally conductive holder (18) in which the channel (14) and the sleeve (20) are held, wherein the thermally conductive holder (18) circumferentially surrounds the channel (14) and the sleeve (20) and has at least one radiotransparent window (38) which is assigned to the irradiation unit (22). Furthermore, a use of the device (10) with a curable compound is specified.
