Risposta rapida: acquirenti che lavorano su waterborne metal packaging inks usually get a cleaner first shortlist when they stop asking one additive to solve every print complaint at once and instead separate tre lavori diversi. CHLUMIWE® 2100 should move first when the ink still needs better wetting, spread, and lower-surface-tension entry on smooth or decorated metal surfaces. CHLUMIAG® 3501 deserves earlier review when the ink already prints directionally but the dried print face still needs anti-sticking, release, or downstream handling control. CHLUMIAF® 3062 is the cleaner first move when the real bottleneck is foam, microbubbles, or circulation-side air entrainment in a waterborne route.
This page stays inside the redirected CHLUMICRYL® Additivi per vernici e inchiostri direction and does non drift back to the older photoinitiator cluster. It also is not a duplicate of Longchang’s already-live metal packaging ink additives page, which covers the broader chemistry window. The buyer question here is narrower: which additive deserves the first trial when the ink is specifically waterborne, printed on metal packaging, and still not giving a commercially stable result?
Why waterborne metal packaging inks deserve their own additive page
A waterborne metal packaging ink sits in a tighter buyer lane than a broad metal-packaging-ink article because the formulation has to keep together water-based process behavior, difficult non-absorbent surface wettinge dried-face handling after printing. A lab drawdown can look acceptable while the live job still fails commercially because the ink does not wet the decorated metal cleanly, the printed face still blocks or drags after drying, or the circulating system keeps pulling air into the ink.
That makes waterborne metal packaging a cleaner application split than another generic packaging-ink page. Buyers often need to separate a surface-entry problem, UN dried-face handling probleme un waterborne foam problem before they can judge the rest of the package honestly. Those are different first screens, even when the same trial shows more than one symptom.
General industry framing supports that split conservatively. Waterborne packaging inks on metal surfaces are commonly judged by whether they wet the substrate cleanly, whether the dried print face still behaves acceptably in later contact or finishing steps, and whether foam or entrained air keeps disturbing stability. The product-specific facts below still stay tied to current Longchang-supported product pages.
What the current company-supported evidence actually separates
- CHLUMIWE® 2100 is supported by Longchang as a multi-component modified polydimethylsiloxane route with surface tension below 25 mN/m, a recommended dosage of Da 0,1% a 1,0%, suitability for difficult-to-wet substrates, and applicability across UV, solventee sistemi a base d'acqua. Longchang also states that, with a small amount added, it will non produce schiuma stabile in condizioni di dispersione ad alta velocità . That makes it the cleaner first route when the waterborne metal packaging ink still is not meeting the substrate honestly enough to judge later-stage handling.
- CHLUMIAG® 3501 is the broader print-face handling and anti-sticking route. Longchang lists it for inchiostri da stampa, inchiostri a getto d'inchiostro, inchiostri per serigrafia, vernici di sovrastampa, rivestimenti antiaderentie anti-sticking-agent use, while also supporting use across UV, solventee sistemi a base d'acqua. The current public page also says it can be added at any stage o più tardi.
- CHLUMIAF® 3062 is supported by Longchang as a polisilossano modificato con polieteri defoamer with a recommended dosage of Da 0,1% a 0,5% per inchiostri da stampa, and applicability across UV, solventee sistemi a base d'acqua. The public page adds a practical note that if solvent dilution is used, stability and defoaming performance should be tested first.
That is enough company-supported separation to build a real B2B buyer page without inventing unsupported food-contact, migration, or regulatory claims. The goal is not to claim one additive fixes every waterborne metal-packaging issue. The goal is to help the buyer choose the first better trial route.
Tabella comparativa rapida: quale percorso merita di essere visualizzato per primo?
| Buyer priority in waterborne metal packaging inks | Il miglior primo percorso | Perché appartiene al primo posto | Punto di osservazione principale |
|---|---|---|---|
| The ink still hesitates, retracts, or spreads weakly on smooth decorated metal or coated can-sheet surfaces | CHLUMIWE® 2100 | The supported route is built around very low surface tension, difficult-substrate wetting, and broad water-based applicability | Use it when the first problem is still substrate entry, not when the real complaint starts after drying on the printed face |
| The print already transfers directionally, but the dried face still blocks, drags, or handles poorly in later contact or finishing steps | CHLUMIAG® 3501 | Longchang directly supports it for printing-ink use, anti-sticking logic, and broader downstream handling across water-based systems | Do not treat it as a substitute for true wetting correction when the ink still cannot enter the surface cleanly |
| Foam, microbubbles, or entrained air are still corrupting process stability or final print appearance | CHLUMIAF® 3062 | Longchang directly positions it as a printing-ink defoamer and supports water-based system use | It is a defoaming route, not the first answer to a dried-face handling issue or a missing wetting route |
When CHLUMIWE® 2100 is the better first move
2100 should move first when the waterborne metal packaging project still looks like a substrate-entry problem. This is the cleaner starting route when the ink is not spreading or covering the target surface cleanly enough to judge the rest of the package honestly.
That distinction matters because waterborne metal-packaging teams often see more than one complaint at once. A weakly wetting ink can also look rough, unstable, or air-sensitive simply because the film never settled correctly on the metal surface in the first place. If the surface-entry route is still wrong, later handling or defoaming trials become harder to read.
- Utilizzo ottimale come primo schermo: difficult-surface wetting and spread in waterborne metal packaging inks
- Supported dosage window: Da 0,1% a 1,0% della formulazione totale
- Punto di forza principale: lower surface tension and cleaner substrate entry for difficult surfaces
- Avvertenza principale: keep it as the first move when wetting is the dominant bottleneck, not when the print already lands acceptably and the real complaint starts later
In short, 2100 is the better first move when the question is still how the waterborne ink meets the metal packaging surface.
When CHLUMIAG® 3501 is the better first move
3501 should move ahead first when the ink already prints directionally but still shows a dried-face handling problem. This route is stronger when the issue is not basic surface entry, but blocking, sticking, drag, release-oriented handling, or later contact pressure on the printed face.
That matters in metal packaging because the project is not finished when the ink simply lands on the substrate. Later handling, overprint varnish, stacking, or adjacent finishing steps can expose a different additive problem from the original transfer stage. Longchang’s public page is useful here because 3501 is not positioned only as a narrow coating additive. The supported route keeps together inchiostri da stampa, vernici di sovrastampa, rivestimenti antiaderentie anti-sticking use, while staying open across UV, solventee sistemi a base d'acqua.
- Utilizzo ottimale come primo schermo: anti-sticking, release, and downstream handling control after the waterborne metal packaging ink already transfers directionally
- Compatibilità del sistema: UV, solvent, and water-based systems on the current public page
- Punto di forza principale: one route that already supports printing-ink use plus broader handling logic
- Avvertenza principale: if the printed film still has obvious wetting failure, 3501 should not be used to hide a problem that still belongs to the 2100 route first
So 3501 is the better first move when the waterborne metal packaging project needs a handling-first cleanup route after transfer is already directionally acceptable.
When CHLUMIAF® 3062 is the better first move
3062 should move ahead first when the waterborne metal packaging line is being limited by schiuma, microbolle, O air entrainment. In those cases, a better wetting route or a better handling route usually will not give the team an honest print read until the foam pressure is under control.
Longchang’s public product page is direct here. 3062 is positioned as a printing ink defoamer, supports a Da 0,1% a 0,5% dosage window for printing inks, and remains open to sistemi a base d'acqua. That makes it commercially useful in waterborne metal packaging, where circulation, pumping, and press-side agitation can keep feeding air into the ink even after the drawdown itself looks acceptable.
- Utilizzo ottimale come primo schermo: persistent foam, microbubble carry-through, or waterborne air-release problems in metal packaging inks
- Supported dosage window: 0.1% to 0.5% of total formulation for printing inks
- Punto di forza principale: a defoaming route directly tied by Longchang to printing inks and water-based systems
- Avvertenza principale: if solvent dilution is part of the process, check stability and defoaming performance before scale-up
This is the stronger first move when the visible defect is being limited by air management, not by missing wetting or missing handling control.
Come gli acquirenti dovrebbero scegliere prima di richiedere i campioni
1. Start with the real first failure on the line
If the waterborne metal packaging ink still hesitates on the substrate, start with 2100. If the ink already transfers directionally but still handles badly after drying, move 3501 forward. If foam or microbubbles are still corrupting the print read, start with 3062.
2. Keep substrate entry separate from dried-face handling
A waterborne metal packaging ink that cannot wet the surface cleanly and a waterborne metal packaging ink that prints acceptably but still blocks during later contact are not the same additive problem. Separating those routes early usually makes the first trial set much more honest.
3. Keep foam control separate from both surface routes
Defoaming is not just a smaller version of wetting correction or anti-sticking control. If entrained air is still sitting in the system, it can distort how the team reads every later additive on the line.
4. Respect the watchpoint, not only the headline benefit
2100 brings a substrate-entry route. 3501 brings a broader anti-sticking and handling route. 3062 brings a direct printing-ink defoaming route. Those practical differences usually decide the better first route more than the additive family name alone.
5. Keep the first trial set small
For many buyers, one 2100 wetting route, uno 3501 handling routee uno 3062 defoaming route teach more than an overloaded first screen filled with partially overlapping additives.

FAQ
Which additive should I screen first if a waterborne metal packaging ink still is not spreading cleanly?
Usually 2100, because the supported route is built around very low surface tension and difficult-substrate wetting, which matches a real entry-and-spread problem more directly than a handling or defoaming route.
When should 3501 move ahead of 2100?
3501 should move ahead when the ink already transfers directionally but the dried print face still blocks, drags, or handles poorly during later contact, varnish, or finishing steps.
When does 3062 make more sense than the other two?
It makes more sense when foam, microbubbles, or air entrainment still dominate the visible defect pattern and the team needs a printing-ink defoamer route rather than another surface-control trial.
Is this page the same as the broader metal-packaging-ink additives page?
No. The broader page still answers the wider application question across chemistry windows. This page is narrower and helps waterborne metal-packaging buyers decide whether the first bottleneck is substrate entry, dried-face handling, or waterborne foam.
Does this page make food-contact or regulatory claims for packaging work?
No. This page stays focused on additive-selection logic for waterborne metal-packaging workflows. Any compliance, migration, or final end-use qualification still needs separate formulation and regulatory review.
Passo successivo
If your waterborne metal packaging project is stuck between weak substrate entry, dried-face handling pressuree circulation-side foam, stop treating them as the same additive request. Start with the real bottleneck first. That usually makes the next CHLUMICRYL® sample decision faster and more commercially useful.
