TIANCURE 369 |
General: |
TIANCURE 369 is a highly efficient UV curing agent which is used to initiate the photopolymerisation of chemically prepolymers - e.g. acrylates - in combination with mono- or multifunctional monomers.
TIANCURE 369 is especially suitable for pigmented UV curable systems, photoresists and printing plates. |
Chemical Composition: |
 |
UV Transmittance Spectrum: (% in Acetonitrile) |
 |
Physical Properties : |
Appearance: Slightly yellow powder
Melting range: 110-114ºC
Solution Clarity at 20°C (g/100 g solution):
Acetone 17, Butyacetate 11, Toluene 27, Hexanedioldiacrylate (HDDA) 5 |
Application: |
TIANCURE 369 may be used after adequate testing alone or in combination with suitable coinitiators, such as Photoinitator 184 and Photoinitator 651, for UV curable inks and varnishes for applications on paper, metal and plastic materials. Its high absorptivity makes it especially suitable for UV curable inks.
Applications in the graphic arts (e.g. offset and screen inks, printing plates, etc.) and in the electronics industry (e.g. photoresists, solder masks, etc.) may also be of interest.
The amount of Photoinitator 369 required for optimum performance should be determined in trials covering a concentration range. of it is known to be limited. |
Recommended concentrations : |
| Offset inks |
2 – 4 % TIANCURE 369 |
| Screen inks |
2 – 4 % TIANCURE 369 |
| Pigmented coatings |
+ 1 – 3 % TIANCURE 184 |
| |
1 – 4 % TIANCURE 369 |
| Photopolymers for imaging applications |
0.5 – 5 % TIANCURE 369 |
|
Safety and Handling: |
TIANCURE 369 should be handled in accordance with good industrial
practice. TIANCURE 369 is sensitive to visible light and any exposure to sunlight should be avoided. Opened packaging should be closed after use to protect the product against light. |
