Er geh\u00f6rt zur Familie der Iodoniumhexafluorophosphate und ist ein wichtiges Mitglied der kationischen Photoinitiatoren. Im Gegensatz zu anderen \u00e4hnlichen Substanzen ist 938 speziell f\u00fcr Nicht-Silizium-Anwendungen konzipiert. Genau wie die kationischen UV-h\u00e4rtenden Druckfarben, die wir in der industriellen Produktion h\u00e4ufig sehen, hat sein Erscheinen die Aush\u00e4rtungsgeschwindigkeit erheblich beschleunigt und einen qualitativen Sprung in der Produktionseffizienz gebracht.<br \/>\n938 erscheint in Form eines kristallinen Pulvers. Diese einzigartige physikalische Form verleiht ihm ausgezeichnete Hafteigenschaften, insbesondere auf Metallsubstraten, wo es eine magische \"Haftkraft\" zu haben scheint. 938 zeigt auch beeindruckende Vorteile bei der Anwendung von transparenten Beschichtungen und Filmen - geringe Vergilbung. Diese Eigenschaft kommt nicht von ungef\u00e4hr, sondern beruht auf komplexen chemischen Prinzipien. Wenn Beschichtungen und Folien \u00fcber einen l\u00e4ngeren Zeitraum verwendet oder bestimmten Umgebungen ausgesetzt werden, vergilben viele Materialien aufgrund von Oxidation, Licht und anderen Faktoren, was das Aussehen und die Qualit\u00e4t des Produkts ernsthaft beeintr\u00e4chtigt. Der geringe Vergilbungseffekt von 938 ist wie ein \"Schutzmantel\" f\u00fcr diese Produkte, der es ihnen erm\u00f6glicht, auch im Laufe der Zeit ein gutes Aussehen zu behalten.<\/div>\n<div><\/div>\n<div class=\"auto-hide-last-sibling-br paragraph-u1TS5p paragraph-element br-paragraph-space\">Dar\u00fcber hinaus hat 938 ein sehr breites Anwendungsspektrum. Es eignet sich hervorragend f\u00fcr die Aush\u00e4rtung von alicyclischen Epoxidharzen, Vinylethern, Glycidylethern, Oxetanen, Epoxiden und anderen kationisch h\u00e4rtenden Materialien. Dies ist auf seine einzigartige chemische Struktur zur\u00fcckzuf\u00fchren, die mit den Molek\u00fclen in diesen Materialien reagieren kann, um eine effiziente Aush\u00e4rtung zu erreichen.<\/div>\n<div><\/div>\n<div class=\"auto-hide-last-sibling-br paragraph-u1TS5p paragraph-element br-paragraph-space\">Es ist erw\u00e4hnenswert, dass die maximale Absorptionswellenl\u00e4nge von 938 241 nm betr\u00e4gt, was f\u00fcr seine Anwendung in UV-h\u00e4rtbaren Formulierungen und LED-h\u00e4rtbaren Formulierungen entscheidend ist. In der Praxis zeigt es, wenn es diesen Formulierungen in einer Konzentration von 0,5 - 5 wt% zugesetzt wird, eine hohe Reaktivit\u00e4t und L\u00f6slichkeit in kationischen Systemen. Es ist wie ein perfektes \"chemisches Team\", bei dem jedes Mitglied (938 Molek\u00fcle) in der richtigen Konzentration optimal funktioniert. Aus chemisch-kinetischer Sicht gew\u00e4hrleistet dieser Konzentrationsbereich, dass die Reaktion schnell und vollst\u00e4ndig abl\u00e4uft, ohne Probleme wie \u00dcberreaktion oder Ausf\u00e4llung aufgrund einer zu hohen Konzentration oder langsame Reaktion und unvollst\u00e4ndige Aush\u00e4rtung aufgrund einer zu niedrigen Konzentration.<\/div>\n<div><\/div>\n<div class=\"auto-hide-last-sibling-br paragraph-u1TS5p paragraph-element br-paragraph-space\">Die Bedeutung von 938 l\u00e4sst sich auch anhand der historischen Entwicklung von Werkstoffen nachvollziehen. In der fr\u00fchen industriellen Produktion war die Entwicklung der UV-H\u00e4rtungstechnologie durch den Mangel an effizienten Fotoinitiatoren wie 938 stark eingeschr\u00e4nkt. In der Druckindustrie beispielsweise beeintr\u00e4chtigte die langsame Aush\u00e4rtungsgeschwindigkeit der Druckfarben nicht nur die Produktionseffizienz, sondern f\u00fchrte auch zu einer instabilen Druckqualit\u00e4t. Die Einf\u00fchrung von 938 war wie eine \"Revolution\" f\u00fcr die Industrie, die sowohl die Qualit\u00e4t als auch die Produktionsgeschwindigkeit von Druckerzeugnissen erheblich verbesserte.<\/div>\n<p>&nbsp;<\/p>\n<p><strong><b>Anwendungen<\/b><\/strong><\/p>\n<p>\u2981 Klare Beschichtungen<\/p>\n<p>\u2981 Pigmentierte Systeme<\/p>\n<p>\u2981 LED-H\u00e4rtung<\/p>\n<p>\u2981 Elektronik<\/p>\n<p>\u2981 Klebstoffe<\/p>\n<p>\u2981 3D-Druck<\/p>\n<p>&nbsp;<\/p>\n<p><strong><b>Paket: <\/b><\/strong>Trommel ,botte.<\/p>\n<p><strong><b>Lagerung:<\/b><\/strong><\/p>\n<p>An einem k\u00fchlen, trockenen Ort ohne direkte Sonneneinstrahlung aufbewahren.<\/p>\n<h2><strong><b>Kontaktieren Sie uns jetzt!<\/b><\/strong><\/h2>\n<h4><strong><b>Wenn Sie einen Preis ben\u00f6tigen, tragen Sie bitte Ihre Kontaktdaten in das unten stehende Formular ein.
