RadTech 2022 Highlights Next Level Formulations

Peb qhov kev sib cais tawm qhia txog cov thev naus laus zis tshiab tau muab rau hauv thaj chaw kho hluav taws xob.

Ib qho ntawm qhov tseem ceeb ntawm RadTech lub rooj sib tham yog cov kev sib tham ntawm cov thev naus laus zis tshiab. NtawmRadTech 2022, muaj peb qhov kev sib tham rau Cov Txheej Txheem Ntxiv Ntxiv, nrog rau cov ntawv thov xws li ntim khoom noj, txheej ntoo, txheej tsheb thiab lwm yam.

Tom ntej no Theem Formulations I

Bruce Fillipo ntawm Ashland tau coj tawm Cov Txheej Txheem Tom ntej Kuv tau ntsib nrog "Monomer Impact on Optical Fiber Coatings," saib seb cov polyfunctionals tuaj yeem cuam tshuam cov fibers optical li cas.

"Peb tuaj yeem tau txais kev sib koom ua ke monofunctional monomer lub zog nrog polyfunctionals - viscosity suppression thiab txhim kho solubility," Filippo sau tseg. "Kev txhim kho formulation homogeneity pab txhawb homogeneous crosslinking ntawm polyacrylates.

"Vinyl pyrrolidone ntsuas qhov zoo tshaj plaws tag nrho cov khoom imparted rau ib tug thawj optical fiber formulation, nrog rau zoo heev viscosity suppression, superior elongation thiab tensile lub zog, thiab ntau dua los yog sib npaug tus nqi kho thiab lwm yam kev soj ntsuam monofunctional acrylates," ntxiv Fillipo. "Cov khoom lag luam tsom rau hauv cov txheej txheem fiber ntau zoo ib yam li lwm yam UV curable daim ntaub ntawv xws li inks thiab coatings tshwj xeeb."

Marcus Hutchins ntawm Allnex ua raws li "Ua tiav Ultra-Low Gloss Txheej Los Ntawm Oligomer Tsim thiab Tshuab." Hutchins tau tham txog txoj hauv kev rau 100% UV txheej nrog cov neeg ua haujlwm matting, piv txwv li ntoo.

"Txoj kev xaiv rau kev txo qis ntxiv nrog rau cov resins nrog kev ua haujlwm qis dua thiab tsim cov neeg ua haujlwm matting," Hutchins ntxiv. "Kev txo qis gloss tuaj yeem ua rau cov cim marring. Koj tuaj yeem tsim cov nyhuv wrinkle los ntawm excimer curing. Cov cuab yeej teeb tsa yog qhov tseem ceeb los ua kom lub ntsej muag du yam tsis muaj qhov tsis xws luag.

Hutchins hais ntxiv tias "Cov txheej txheem qis qis thiab cov txheej txheem ua haujlwm siab tau dhau los ua qhov tseeb," Hutchins ntxiv. "UV cov ntaub ntawv kho tau tuaj yeem ua tau zoo los ntawm kev tsim qauv thiab thev naus laus zis, txo cov neeg ua haujlwm matting xav tau thiab txhim kho qhov kub hnyiab thiab stain resistance."

Richard Plenderleith ntawm Sartomer tom qab ntawd tham txog "Cov Tswv Yim Rau Kev Txom Nyem Qhov Muaj Peev Xwm Loj hauv Cov Duab Duab." Plenderleith tau taw qhia tias li ntawm 70% ntawm kev ntim khoom yog rau ntim khoom noj.

Plenderleith ntxiv tias tus qauv UV inks tsis haum rau kev ntim khoom noj ncaj qha, thaum tsis muaj kev tsiv teb tsaws UV inks yuav tsum tau ntim khoom noj tsis ncaj.

Plenderleith hais tias "Kev xaiv cov khoom siv tau zoo yog qhov tseem ceeb kom txo qis kev pheej hmoo ntawm kev tsiv teb tsaws chaw," Plenderleith hais. "Cov teeb meem tuaj yeem tshwm sim los ntawm yob cov kab mob thaum luam ntawv, UV teeb tsis kho thoob plaws, lossis teeb tsa kev tsiv teb tsaws chaw thaum khaws cia. UV tshuab yog ib feem ntawm kev lag luam ntim zaub mov loj hlob vim nws yog cov tshuab tsis muaj kuab tshuaj. "

Plenderleith tau taw qhia tias kev ntim khoom noj yuav tsum nruj dua.

"Peb pom muaj zog txav mus rau UV LED, thiab kev txhim kho cov kev daws teeb meem ua tau raws li qhov xav tau ntawm LED kho yog qhov tseem ceeb," nws hais ntxiv. "Kev txhim kho reactivity thaum txo kev tsiv teb tsaws thiab kev phom sij xav kom peb ua haujlwm ntawm ob qho tib si photointiators thiab acrylates."

Camila Baroni ntawm IGM Resins kaw Cov Txheej Txheem Qib Tom ntej Kuv nrog "Cov nyhuv Synergistic ntawm Kev Sib Txuas Cov Khoom Siv Aminofunctional nrog Hom I Photoinitiators."

"Los ntawm cov ntaub ntawv qhia txog tam sim no, nws zoo li qee cov acrylated amines yog cov pa oxygen inhibitors zoo thiab muaj peev xwm ua kom muaj kev sib koom ua ke nyob rau hauv muaj hom 1 photoinitiators," Baroni tau hais. "Qhov feem ntau reactive amines ua rau tsis xav yellowing nyhuv ntawm cov yeeb yaj kiab kho. Peb tau xav tias qhov daj tuaj yeem raug txo los ntawm kev ua kom zoo ntawm cov ntsiab lus acrylated amine. "

Tom ntej no Theem Formulations II

Tom ntej no Theem Formulations II pib nrog "Small Particle Sizes Pack a Punch: Additive Options to improve Surface Performance of UV Coatings Use Cross-Linkable, Nanoparticle Dispersions or Micronized Wax Options," nthuav tawm los ntawm Brent Laurenti ntawm BYK USA. Laurenti tham txog UV crosslinking additives, SiO2 nanomaterials, additives thiab PTFE-free wax technology.

Laurenti tau tshaj tawm tias "PTFE-dawb waxes ua rau peb ua tau zoo dua hauv qee qhov kev siv, thiab lawv yog 100% biodegradable," Laurenti tau tshaj tawm. "Nws tuaj yeem nkag mus rau hauv yuav luag txhua txheej txheej."

Tom ntej no yog Tony Wang ntawm Allnex, uas tau tham txog "LED Boosters los txhim kho Surface Kho los ntawm LED rau Litho lossis Flexo Applications."

"Oxygen inhibition quenches lossis scavenges radical polymerization," Wang sau tseg. "Nws yog qhov hnyav dua nyob rau hauv cov txheej nyias lossis cov viscosity tsawg, xws li ntim txheej thiab inks. Qhov no tuaj yeem tsim qhov chaw tacky. Kev kho qhov saum npoo yog qhov nyuaj dua rau kev kho LED vim qhov kev siv qis thiab ntsuas phoo ntawm luv luv wavelength. "

Evonik's Kai Yang tom qab ntawd tham txog "Txhawb Lub Zog Kho Kom Zoo Tshaj Plaws rau Cov Txheej Txheem Yooj Yim - Los Ntawm Ib Qhov Ntxiv Ntxiv."

"PDMS (polydimethylsilozanes) yog cov chav kawm yooj yim tshaj plaws ntawm siloxanes, thiab muab qhov nro qis heev thiab ruaj khov," Yang pom. “Nws muab cov khoom zoo gliding. Peb txhim kho kev sib raug zoo los ntawm kev hloov kho cov organic, uas tswj nws cov hydrophobicity thiab hydrophilicity. Cov khoom uas xav tau tuaj yeem raug kho los ntawm kev sib txawv ntawm cov qauv. Peb pom tias ntau dua polarity txhim kho solubility hauv UV matrix. TEGO Glide pab tswj cov khoom ntawm organomodified siloxanes, thaum Tego RAD txhim kho plam thiab tso tawm. "

Jason Ghaderi ntawm IGM Resins kaw Qib Tom ntej Formulations II nrog nws cov lus hais txog "Urethane Acrylate Oligomers: rhiab heev ntawm cov yeeb yaj kiab kho mob rau UV Teeb thiab noo nrog thiab tsis muaj UV Absorbers."

"Tag nrho cov qauv raws li UA oligomers pom tias tsis muaj yellowing rau ntawm qhov muag liab qab thiab zoo li tsis yellowing los yog discoloration raws li ntsuas los ntawm lub spectrophotometer," Ghaderi hais. "Mos urethane acrylate oligomers pom muaj zog tensile thiab modulus thaum nthuav tawm hauv siab elongation. Semi-hard oligomers kev ua tau zoo nyob hauv nruab nrab, qhov nyuaj oligomers ua rau muaj zog tensile siab thiab modulus nrog qis elongation. Nws tau pom tias UV absorbers thiab HALS cuam tshuam nrog kev kho, thiab vim li ntawd, kev sib txuas ntawm cov yeeb yaj kiab kho tau qis dua li ntawm cov kab ke uas tsis muaj ob qho no. "

Tom ntej no Theem Formulations III

Tom ntej no Theem Formulations III featured Joe Lichtenhan ntawm Hybrid Plastics Inc., uas tau hais txog "POSS Additives for Dispersion and Viscosity Control," saib zoo li POSS additives, thiab yuav ua li cas lawv thiaj li suav tau tias yog cov khoom siv ntse hybrid additives rau txheej txheej txheej.

Lichtenhan tau ua raws li Evonik's Yang, nws qhov kev nthuav qhia thib ob yog "Kev Siv Silica Additives hauv UV Printing Inks."

"Hauv UV / EB curing formulations, qhov chaw kho silica yog cov khoom nyiam vim tias kev ruaj ntseg zoo tuaj yeem ua tau yooj yim dua thaum tuav cov viscosity zoo rau kev luam ntawv," Yang sau tseg.

"UV Curable Coating Options for Interior Automotive Applications," los ntawm Kristy Wagner, Red Spot Paint, yog tom ntej.

"UV curable clear and pigmented coatings have shown that they not only meet but over tam sim no OEM stringent specifications for interior automotive applications," Wagner soj ntsuam.

Mike Idacavage, Radical Curing LLC, kaw nrog "Low Viscosity Urethane Oligomers uas Ua Haujlwm raws li Reactive Diluents," uas nws tau sau tseg tuaj yeem siv rau hauv inkjet, tshuaj tsuag txheej thiab 3D luam ntawv daim ntawv thov.
