- Vibratory needle crosslinking tests are carried out in a tank with a size of 10 x 10 x 40 mm using 1 cm 3 of composition poured into the tank.
- the bottom of the tank is connected to a mercury vapor lamp (high pressure) via an optical fiber.
- the needle plunges up to 2 mm from the bottom of the tank which receives the light beam.
- the minimum duration of exposure is recorded at a given scrolling speed to go from the liquid state to the non-sticky solid state.
- the degree of crosslinking of the films obtained by the methyl ethyl ketone (MEK) test is also defined.
- the mercury arc lamp in the case of cross-linking in a thick layer of 2 mm with RAPRA (vibrating needle), the minimum duration of exposure is recorded to reach 95% of cross-linking (T 95 defined above). ).
- the new control formulation (F'T) becomes:
- the photoinitiator is an iodonium borate of formula (P2) added in solution at 33% w / w in isopropanol:
- This concentrated pigment base is formulated with or without diluent siloxane (a).
- CPTX chlorine 1 propoxy4thioxanthone used as photo-sensitizer.
- the photoinitiator is added in the form of an isopropanolic solution.
- the various constituents are added and mixed until complete dissolution of the thioxanthone CPTX, before addition of the concentrated pigment base.
- the drying of the inks is evaluated on a UV bench from the company FUSION fitted with a mercury lamp doped with gallium. This lamp, which has a power of 120W / cm, was calibrated using a Powerpuck cell from the company EIT, so as to determine the intensity and the dose received as a function of the running speed of the bench. At the running speed of 23 m / min the sample receives:
- UW (390-440 nm) 0.490 J / cm 2 .
- UVA 320-390 nm
- UVB 280-320 nm
- UVC 250-260 nm
- UW 0.416 J / cm 2
- the resistance to solvents of the inks obtained after drying of films of 12 ⁇ m ⁇ 3 is measured, by measuring the number of necessary round trips made using a cloth soaked in solvent to disintegrate the ink layer, 1 hour. after exposure and 24 hours after exposure.
- the solvent used is methyl ethyl ketone (MEK).
- UVC 250-260 nm
- UW 390-440 nm
- 0.343 J / cm 2 At the speed of 100 m / min, the calibration is not significant, taking into account the response time of the cell.
- the solvent used is methyl ethyl ketone (MEK).
- MEK methyl ethyl ketone
- siloxane diluent (a) allows, thanks to its low viscosity, to facilitate spreading on the support and the mixture of the constituents.
- the drying of the inks is evaluated on a UV bench from the IST Company equipped with two 200 W / cm lamps. A gallium-doped mercury lamp and an undoped mercury lamp.
- the calibration of the lamps is the same as before.
