Abstract:
Procedimiento para curar compuestos polimerizables etilénicamente insaturados para producir revestimientos, manos de gel, materiales compuestos o adhesivos que tienen secciones gruesas más gruesas de aproximadamente 0.25 mm, en el que los compuestos polimerizables etilénicamente insaturados son (a) una mezcla de (i) poliésteres insaturados y (ii) acrilatos, metacrilatos, estireno o mezclas de los mismos, o (b) una mezcla de (i) poliesteracrilatos insaturados y en donde, además, (ii) acrilatos, metacrilatos o combinaciones de los mismos, el procedimiento comprende añadir a dichos compuesto al menos un fotoiniciador de óxido de acilfosfina e irradiar la mezcla así obtenida con radiación procedente de una fuente de diodos fotoemisores.
Abstract:
The invention relates to low-viscosity formulations of radiation-curable compounds, methods for the production thereof, the use thereof, and inks, printing inks, and printing varnishes containing said compound formulations.
Abstract:
Disclosed are functional polyallophanate oligomers comprising ethylenically unsaturated groups and polymer stabilizer groups selected from hindered amine light stabilizers, ultraviolet light absorbers, antioxidants and dihydrocarbylhydroxylamines. The ethylenically unsaturated groups and the polymer stabilizer groups are bound to the polyallophanate oligomers through allophanate and/or carbamate groups. The polyallophanate oligomers are useful in curable coatings, inks and varnishes. The present polyallophanate oligomers are derived from a) organic polyisocyanates, b) compounds containing at least one isocyanate reactive group and at least one ethylenically unsaturated group and c) polymer stabilizers containing at least one isocyanate reactive group.
Abstract:
Disclosed is a process for photocuring certain thick layer ethylenically unsaturated systems with a light emitting diode (LED) light source. The thick curable compositions are thick coatings, gel coats, composites and adhesives. The photoinitiator is at least one bisacylphosphine oxide or monoacylphosphine oxide. The process provides for excellent surface cure and through cure.
