Réponse rapide : les acheteurs qui choisissent additives for corrugated box inks usually get a more useful first shortlist when they separate three different additive jobs instead of asking one product to solve every board-print problem at once. CHLUMIWE® 3280 devrait intervenir en premier lorsque le problème principal est board-side wetting, spread, or cleaner laydown on coated liners, white-top board, or other harder-to-wet corrugated print surfaces. CHLUMIAG® 3501 deserves earlier review when the buyer needs a broader print-face handling, antiadhésif, ou rub-sensitive stack compatibility itinéraire. CHLUMIAF® 3062 belongs earlier when the system already looks directionally right but foam, entrained air, or circulation-side instability keeps damaging consistency.
That is the commercially useful split. This page is not another generic flexographic-ink overview and it is not a minor rewrite of the live folding carton ink additives page. It is a narrower CHLUMICRYL® application page for buyers who already know the project is a corrugated-box ink job and need a better first screen before requesting samples.
Why corrugated box inks deserve their own additive page
Corrugated-box printing creates a different buyer question from general flexographic or label work. In conservative industry framing, corrugated programs often separate board wetting and coverage, print-face rub or stack-handling pressureet foam control in circulating water-based systems instead of treating them as one vague additive decision. That distinction matters because a corrugated line can look acceptable in a quick drawdown yet still become commercially weak once the ink has to wet uneven board surfaces, survive stack pressure, or stay stable through pumps, chambers, and recirculation.
Longchang possède déjà des pages en direct pour flexographic ink additives, label ink additives, folding carton ink additiveset CHLUMICRYL® Additifs pour revêtements et encres. Those pages answer adjacent process or packaging questions. This page answers the tighter B2B question that comes later in the project: which Longchang-supported route should lead when the application is specifically corrugated-box ink work?
Ce que les faits actuellement étayés par l'entreprise permettent déjà de distinguer
- CHLUMIWE® 3280 is supported by Longchang as a polysiloxane modifié par un polyéther wetting agent with recommended dosage at 0.2% to 3.0% of total formulation, addition during grinding, stirring, ou after production, optional solvent pre-dilution, and applicability across UV, solvantet systèmes à base d'eau. The supported page also ties it to difficult substrates and the broader printing-inks and packaging-coatings lane.
- CHLUMIAG® 3501 is supported by Longchang as a polysiloxane modifié multicomposant that can be added at any stage and used across UV, solvantet systèmes à base d'eau. The current company-supported page directly lists encres d'imprimerie, encres pour jet d'encre, vernis de surimpression, revêtements antiadhésifset anti-sticking-agent use.
- CHLUMIAF® 3062 est le voie d'abord antimousseLongchang le soutient pour encres d'imprimerie avec une dose recommandée de 0,1% à 0,5% of total formulation, broad UV, solvantet à base d'eau applicability, and the practical watchpoint that if solvent dilution is used, stability and defoaming performance should be tested first.
That is enough product-level separation to build a real shortlist for corrugated-box inks without inventing unsupported box-strength, food-contact, or compliance claims.
Tableau comparatif rapide : quel itinéraire mérite la première place ?
| Buyer priority in corrugated-box inks | Meilleur premier itinéraire | Pourquoi cela devrait être la première chose à faire | Point de surveillance principal |
|---|---|---|---|
| Poor corrugated-board contact, weak spread, or a drawdown that still looks like a wetting-first problem | CHLUMIWE® 3280 | Longchang supports it as a difficult-substrate wetting route with a broad dosage window and system fit across UV, solvent, and water-based systems | Keep the first screen focused on wetting and spread instead of expecting one additive to solve every stack-handling issue |
| Broader anti-sticking pressure, print-face rub behavior, or downstream handling compatibility after printing | CHLUMIAG® 3501 | The product page directly combines printing-ink use with overprint varnishes, release coatings, and anti-sticking-agent positioning | Because it is a broader compatibility route, define the real KPI before screening so the result stays interpretable |
| Persistent foam, entrained air, or circulation-side instability during ink manufacture, pumping, or printing | CHLUMIAF® 3062 | Longchang directly supports it as a printing-ink defoamer with a dedicated dosage window and broad system applicability | If solvent dilution is used, stability and defoaming performance should be checked before scale-up |
When CHLUMIWE® 3280 is the better first move
3280 should move to the front when the corrugated-box project still looks like a wetting and spread problem. This is often the cleaner first route when the ink is not laying down cleanly on white-top linerboard, coated corrugated surfaces, preprinted facings, or other surfaces that behave less predictably than plain absorbent kraft. It is also useful when the lab needs a clearer first benchmark before moving into broader handling and foam tradeoffs.
The current Longchang page gives 3280 a useful operating window for that job. It supports 0.2% to 3.0% dosage, can be added during grinding, stirring, or after production, and can be diluted with eau, alcools, alcanes et composés aromatiques. The same page also highlights difficult-substrate use and keeps the route inside the broader printing-ink and packaging-coating lane.
- Best first-screen use: coated-liner wetting, spread, and initial laydown screening on harder-to-wet corrugated print surfaces
- Dosage guidance: 0.2% to 3.0% of total formulation
- System fit: Systèmes à base d'UV, de solvants et d'eau
- Commercial reason to shortlist it: it gives a cleaner first answer when the buyer still needs basic board contact to improve before testing broader handling or foam-control routes
In short, 3280 is the better first move when the real question is still how the ink meets the corrugated surface.
When CHLUMIAG® 3501 is the better first move
3501 deserves earlier review when the project is no longer only about first contact. It is the stronger route when the buyer needs a broader antiadhésif, release-oriented, ou print-face compatibility path that can still sit naturally inside a corrugated-box ink branch.
The current Longchang page is clear here. 3501 is not only listed for encres d'imprimerie; it is also publicly positioned for encres pour jet d'encre, vernis de surimpression, revêtements antiadhésifset anti-sticking-agent use. It can be added at any stage and used across UV, solvantet systèmes à base d'eau.
- Best first-screen use: broader print-face handling questions, including anti-sticking, rub-sensitive stacking, and downstream finishing compatibility
- Addition logic: can be added at any stage or later
- System fit: Systèmes à base d'UV, de solvants et d'eau
- Commercial reason to shortlist it: it is the cleaner route when the buyer needs a wider box-print handling path instead of only a wetting correction
That makes 3501 the better first move when the problem sits more in stack handling, rub behavior, or downstream compatibility than in basic spread.
When CHLUMIAF® 3062 is the better first move
3062 should move first when the corrugated-box ink project already has a plausible wetting route but the system keeps failing because of mousse, entrained air, ou poor process stability. That is a different job from improving first contact or tuning print-face handling. It is also one that can waste a lot of development time if the team keeps screening more surface additives before solving the foam problem.
Longchang supports 3062 as a polysiloxane modifié par un polyéther defoamer for encres d'imprimerie, with a recommended dosage at 0,1% à 0,5% of total formulation and applicability across UV, solvantet systèmes à base d'eau. The product page also adds a practical note: if solvent dilution is used, the team should first verify stability and defoaming performance.
- Best first-screen use: foam control, air-release management, and process-side stability in corrugated-box ink workflows
- Dosage guidance: 0.1% to 0.5% of total formulation
- System fit: Systèmes à base d'UV, de solvants et d'eau
- Main caution: test solvent-dilution stability before scale-up if dilution is part of the process plan
So 3062 is the better first move when the project is being limited by gas management, not by missing wetting or print-side compatibility.
Comment les acheteurs doivent choisir avant de demander des échantillons
1. Start with the first visible bottleneck
If the corrugated surface still is not accepting the ink cleanly, start with 3280. If the real issue is broader handling, anti-sticking, or rub-sensitive stack compatibility, move 3501 earlier. If the project is already being damaged by foam or trapped air, move 3062 up.
2. Keep the corrugated workflow visible
This page is intentionally narrower than the broader flexographic and folding-carton pages. A corrugated-box job carries its own pressure around board variation, stack handling, and keeping the printed surface practical through post-print handling. That makes the first additive screen more application-specific than a general flexo page.
3. Do not force a defoamer into a wetting job
If the buyer has not yet solved basic board contact, a wetting-first route usually teaches more than jumping straight to a defoamer. The opposite is also true: once the real problem is foam and air release, a new wetting additive may only add noise to the first screen.
4. Use the watchpoint, not only the headline benefit
3280 is broad, but that does not mean it is the best first route for every downstream issue. 3501 offers a wider handling and compatibility route, but the KPI still needs to stay clear. 3062 can be diluted, but the team should verify stability and defoaming first. Those practical notes often decide the better first sample more than the product family name.
5. Keep the first round tight
For many buyers, one wetting route, un broader print-face handling routeet un voie d'abord antimousse teach more than screening too many nearby additives at once.

FAQ
Which additive should I screen first if a corrugated-box ink is not spreading cleanly?
Usually CHLUMIWE® 3280, because it is the cleaner wetting-first benchmark when the real problem is corrugated-board contact and spread.
When should 3501 move ahead of 3280?
3501 should move ahead when the ink already wets reasonably well but the project still needs a broader anti-sticking, stack-handling, or downstream compatibility route.
When should 3062 move ahead of the other two?
3062 should move ahead when persistent foam, entrained air, or process-side instability is the main barrier to acceptable print quality or manufacturing stability.
Is this page the same as the flexographic-ink page?
No. The flexographic page is process-first. This new page is application-first and helps corrugated buyers separate board wetting, stack-handling pressure, and foam control in a tighter corrugated workflow.
Can one of these additives solve every corrugated-box ink issue?
No. Their supported first-screen logic is different enough that buyers should not treat them as interchangeable. The faster route is to identify whether the problem starts at wetting, handling, or foam control.
Need a faster shortlist for corrugated-box inks?
If your team is stuck between board-side wetting, print-face handling and rub pressureet contrôle de la mousse, define the real first-screen job before requesting samples. That usually shows much faster whether CHLUMIWE® 3280, CHLUMIAG® 3501, or CHLUMIAF® 3062 deserves the first round.
