Resposta rápida: compradores escolhendo additives for waterborne gravure inks usually get a cleaner first shortlist when they stop treating every press-side defect like one vague ink-additive problem and instead separate três empregos diferentes. CHLUMIWE® 2100 should move first when the real bottleneck is difficult-substrate wetting and lower-surface-tension spread on film, foil, or coated stock. CHLUMIAG® 3501 deserves the earlier screen when the ink already transfers 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 blocker is foam, microbubbles, or circulation-side air entrainment in a waterborne gravure route.
That is the commercially useful split. This page stays inside the redirected CHLUMICRYL® Aditivos para tintas e revestimentos direction and does not drift back to the older photoinitiator cluster. It also is not a duplicate of Longchang’s already-live gravure ink additives page, which covers a broader chemistry window, or the already-live waterborne flexographic ink additives e waterborne screen ink additives pages, which answer different process questions first. This new page is narrower: it helps buyers decide which additive deserves the first trial when the ink is specifically waterborne, the process is specifically gravure, and the main pressure sits in transfer quality, dried-face handling, or waterborne foam stability on a fast web line.
Why waterborne gravure inks deserve their own additive page
A waterborne gravure ink sits in a tighter buyer lane than a broad gravure-ink article because the formulation has to keep together water-based process behavior, low-viscosity gravure transfer, e downstream handling after drying, rewinding, or lamination. A lab drawdown can look acceptable while the live job still fails commercially because the ink does not wet the substrate cleanly, the dried print still drags or blocks later, or the circulating or pan-side system keeps carrying air into the ink.
That creates a different first-screen question from the broader gravure page. In practical work, the first additive decision often needs to separate a difficult-substrate wetting problem from a dried-face anti-sticking and handling problem, and both from a true waterborne foam and microbubble problem. Those are not the same first screen, even when the same gravure trial appears to show all three symptoms together.
The general industry framing here is conservative. Waterborne gravure systems commonly are judged first by whether the ink can wet film or coated stock cleanly, whether the printed face stays manageable during rewinding or later converting, and whether foam or entrained air keeps disturbing transfer consistency or film appearance. This page uses that outside framing only lightly while keeping product-level claims 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 tensão superficial muito baixa, suitability for difficult-to-wet substrates, and applicability across UV, solvente, e sistemas à base de água. The current company-supported route also says that, with a small amount added, it will não produz espuma estável sob dispersão em alta velocidade. That makes it the cleaner first route when the waterborne gravure ink still is failing at surface entry rather than later handling.
- CHLUMIAG® 3501 is supported as a polissiloxano modificado multicomponente that can be added at any stage and used across UV, solvente, e sistemas à base de água. Longchang directly places it inside tintas de impressão, tintas de serigrafia, tintas para impressoras jato de tinta, vernizes de sobreimpressão, revestimentos de liberação, e anti-sticking-agent use. That is enough company-supported separation to use it here as a dried-face handling route without inventing unsupported gravure-only product claims.
- CHLUMIAF® 3062 is supported as a polissiloxano modificado com poliéter defoamer with recommended dosage of 0,1% a 0,5% em tintas de impressão, and it is also supported across UV, solvente, e sistemas à base de água. Longchang’s current page positions it as a real printing-ink defoamer route, which makes it the cleaner first move when foam, microbubbles, or air-release instability are the actual press-side bottleneck.
That is enough company-supported separation to build a real buyer page. The goal is not to claim that one additive can solve every waterborne gravure complaint. The goal is to help a buyer choose the first better trial route based on what the ink actually is failing to do.
Tabela de comparação rápida: qual rota merece aparecer em primeiro lugar?
| Buyer priority in waterborne gravure inks | Melhor primeira rota | Por que ele deve ser o primeiro? | Posto de observação principal |
|---|---|---|---|
| The waterborne gravure ink still hesitates, pulls back, or spreads weakly on film, foil, or coated stock | 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 dominant complaint starts after drying on the printed face |
| The ink already transfers directionally, but the dried print still sticks, drags, blocks, or handles poorly during rewinding, lamination, or later conversion | CHLUMIAG® 3501 | Longchang directly supports it for anti-sticking use and broader handling logic across printing-ink and release-oriented applications | Do not treat it as a substitute for real wetting correction when the ink still cannot enter the surface cleanly |
| Foam, microbubbles, or circulation-side air entrainment are still corrupting transfer or final film appearance | CHLUMIAF® 3062 | Longchang directly positions it for printing-ink defoaming and supports water-based applicability | It is a foam-control route, not the first answer to surface slip or difficult-substrate wetting |
When CHLUMIWE® 2100 is the better first move
2100 should move first when the waterborne gravure-ink 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 honestly enough to judge the rest of the package.
That distinction matters because gravure teams often see several complaints at once. A weakly wetting waterborne ink can also look rough, unstable, or foam-prone simply because the film never settled correctly on the surface in the first place. If the entry route is still wrong, it becomes harder to interpret later dried-face or defoaming trials.
- Melhor uso na primeira tela: difficult-substrate wetting and spread in waterborne gravure inks
- Ajuste do sistema: the current company route supports UV, solvent, and water-based systems
- Principal ponto forte: a practical first route when the buyer still needs lower surface tension and cleaner entry on the target surface
- Atenção principal: use it when the dominant problem is wetting and spread, not when the ink already transfers directionally and the real complaint is sticking or foam cleanup
In short, 2100 is the better first move when the question is still how the waterborne gravure ink meets the substrate.
When CHLUMIAG® 3501 is the better first move
3501 should move ahead first when the ink already transfers 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 downstream contact pressure on the printed face.
That matters in waterborne gravure inks because many printed webs are rewound, laminated, slit, or otherwise converted soon after drying. Those downstream steps can expose a different additive problem from the original transfer stage. Longchang’s current product page is useful here because 3501 is not positioned only as a narrow coating additive. The supported route keeps together tintas de impressão, vernizes de sobreimpressão, revestimentos de liberação, e anti-sticking use, while staying open across UV, solvente, e sistemas à base de água.
- Melhor uso na primeira tela: anti-sticking, release, and downstream handling control after the waterborne gravure ink already transfers directionally
- Ajuste do sistema: UV, solvent, and water-based systems on the current public page
- Principal ponto forte: one route that already supports broader print-side handling logic instead of only another wetting screen
- Atenção principal: 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 gravure-ink project needs a handling-first cleanup route after the print already lands acceptably.
When CHLUMIAF® 3062 is the better first move
3062 should move ahead first when the waterborne gravure ink is being limited by foam, microbubbles, ou air-release instability. In those cases, a better wetting route or a better anti-sticking route usually will not give the team an honest film read until the bubble problem is under control.
Longchang’s product page is direct here. 3062 is supported specifically as a printing-ink defoamer, with a recommended dosage window for printing inks and clear applicability to water-based systems. That matters commercially because gravure teams often need a foam-control route that can be screened early without pretending the issue is actually a printed-face slip problem.
- Melhor uso na primeira tela: persistent foam, microbubbles, or waterborne air-release problems in gravure inks
- Orientações sobre a dosagem: 0.1% to 0.5% of total formulation for printing inks
- Principal ponto forte: a true printing-ink defoamer route already supported by Longchang
- Atenção principal: it is not a substitute for a true wetting route or a dried-face anti-sticking route when those are the real first bottlenecks
This is the stronger first move when the visible print defect is being limited by air management, not by a missing wetting route or a missing handling route.
Como os compradores devem escolher antes de solicitar amostras
1. Start with the real first failure on the printed film
If the waterborne gravure ink still hesitates or pulls back on the substrate, start with 2100. If the ink already transfers directionally but still sticks or drags after drying, move 3501 forward. If foam or microbubbles are still corrupting the print read, start with 3062.
2. Keep surface entry separate from dried-face handling
A waterborne gravure ink that cannot wet the substrate cleanly and a waterborne gravure ink that transfers acceptably but still handles poorly are not the same additive problem. Separating those routes early usually makes the first trial set much more honest.
3. Keep foam cleanup separate from both surface routes
Foam and microbubble control are not just smaller versions of wetting correction or slip control. If entrained air is still sitting in the ink, it can distort how the team reads every later additive.
4. Respect the watchpoint, not only the headline benefit
2100 brings a substrate-entry route. 3501 brings a broader dried-face handling route. 3062 brings a true printing-ink defoamer 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 waterborne gravure-ink buyers, one 2100 wetting route, um 3501 handling routee um 3062 foam-control route teach more than an overloaded first screen filled with partially overlapping additives.

PERGUNTAS FREQUENTES
Which additive should I screen first if a waterborne gravure 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 foam-only route.
When should 3501 move ahead of 2100?
3501 should move ahead when the ink already transfers directionally but the dried print still sticks, drags, blocks, or handles poorly during rewinding, lamination, slitting, or later conversion.
When does 3062 make more sense than the other two?
It makes more sense when foam, microbubbles, or circulation-side air-release problems still dominate the visible defect pattern and the team needs a real printing-ink defoamer route rather than another surface-control trial.
Is this page the same as the broader gravure-ink additives page?
No. The broader gravure page still answers the wider application question across UV, solvent, and water-based systems. This page is narrower and helps waterborne gravure-ink buyers decide whether the first problem is surface entry, dried-face handling, or waterborne foam cleanup.
Does this page make regulatory or food-contact claims for packaging work?
No. This page stays focused on additive-selection logic for waterborne gravure-print workflows. Any compliance, migration, or final end-use qualification still needs separate formulation and regulatory review.
Precisa de uma lista mais curta?
If your waterborne gravure-ink project is stuck between weak surface entry, dried-face handling pressure, e waterborne foam carry-through, stop treating them as the same additive request. Start with the real bottleneck. That usually makes the next CHLUMICRYL® sample decision faster and more commercially useful.
