Het behoort tot de familie van jodoniumhexafluorofosfaten en is een belangrijk lid van de kationische fotoinitiatoren. In tegenstelling tot andere soortgelijke stoffen is 938 speciaal ontworpen voor niet-siliciumtoepassingen. Net als de kationische UV-uithardende inkten die we vaak zien in de industri\u00eble productie, heeft de verschijning ervan de uithardingssnelheid enorm versneld, wat een kwalitatieve sprong in productie-effici\u00ebntie met zich meebrengt.<br \/>\n938 verschijnt als een kristallijn poeder. Deze unieke fysieke vorm geeft het uitstekende hechtingseigenschappen, vooral op metalen substraten, waar het een magische \"kleefkracht\" lijkt te hebben. 938 heeft ook indrukwekkende voordelen bij het aanbrengen van transparante coatings en films - weinig vergeling. Deze eigenschap verschijnt niet toevallig, maar heeft te maken met complexe chemische principes. Als coatings en films lange tijd worden gebruikt of worden blootgesteld aan bepaalde omgevingen, worden veel materialen geel door oxidatie, licht en andere factoren, wat het uiterlijk en de kwaliteit van het product ernstig aantast. Het geringe vergelende effect van 938 is als een \"beschermlaag\" voor deze producten, waardoor ze er ondanks de tand des tijds goed blijven uitzien.<\/div>\n<div><\/div>\n<div class=\"auto-hide-last-sibling-br paragraph-u1TS5p paragraph-element br-paragraph-space\">Bovendien heeft 938 een zeer breed toepassingsgebied. Het presteert uitstekend bij het uitharden van alicyclische epoxyharsen, vinyl ethers, glycidyl ethers, oxetanen, epoxiden en andere kationische uithardingsmaterialen. Dit komt door zijn unieke chemische structuur, die kan reageren met de moleculen in deze materialen voor een effici\u00ebnte uitharding.<\/div>\n<div><\/div>\n<div class=\"auto-hide-last-sibling-br paragraph-u1TS5p paragraph-element br-paragraph-space\">Het is vermeldenswaard dat de maximale absorptiegolflengte van 938 241 nm is, wat cruciaal is voor de toepassing in UV-uithardende formuleringen en LED-uithardende formuleringen. In praktische toepassingen, wanneer het wordt toegevoegd aan deze formuleringen in een concentratie van 0,5 - 5 wt%, vertoont het een hoge reactiviteit en oplosbaarheid in kationische systemen. Het is als een perfect \"chemisch team\", waarbij elk lid (938 molecuul) optimaal presteert bij de juiste concentratie. Vanuit chemisch kinetisch oogpunt zorgt dit concentratiebereik ervoor dat de reactie snel en volledig kan verlopen, zonder problemen zoals overreactie of neerslag door een te hoge concentratie, of trage reactie en onvolledige uitharding door een te lage concentratie.<\/div>\n<div><\/div>\n<div class=\"auto-hide-last-sibling-br paragraph-u1TS5p paragraph-element br-paragraph-space\">We kunnen het belang van 938 verder begrijpen vanuit de historische ontwikkeling van materialen. In de vroege industri\u00eble productie werd de ontwikkeling van UV-uithardingstechnologie sterk beperkt door het gebrek aan effici\u00ebnte fotoinitiatoren zoals 938. In de drukindustrie bijvoorbeeld be\u00efnvloedde de trage uithardingssnelheid van inkten niet alleen de productie-effici\u00ebntie, maar leidde ook tot een onstabiele afdrukkwaliteit. De komst van 938 was als een \"revolutie\" voor de industrie, die zowel de kwaliteit als de productiesnelheid van drukwerk aanzienlijk verbeterde.<\/div>\n<p>&nbsp;<\/p>\n<p><strong><b>Toepassingen<\/b><\/strong><\/p>\n<p>\u2981 Heldere coatings<\/p>\n<p>\u2981 Gepigmenteerde systemen<\/p>\n<p>\u2981 LED uitharding<\/p>\n<p>\u2981 Elektronica<\/p>\n<p>\u2981 Kleefstoffen<\/p>\n<p>\u2981 3D printen<\/p>\n<p>&nbsp;<\/p>\n<p><strong><b>Pakket: <\/b><\/strong>Trommel, bot.<\/p>\n<p><strong><b>Opslag:<\/b><\/strong><\/p>\n<p>Bewaren op een koele, droge plek uit direct zonlicht.<\/p>\n<h2><strong><b>Neem nu contact met ons op!<\/b><\/strong><\/h2>\n<h4><strong><b>Als je Price nodig hebt, vul dan je contactgegevens in op het formulier hieronder.
