Snel antwoord: kopers die kiezen voor additives for label inks usually get a faster first shortlist when they separate three different additive jobs instead of asking one product to solve every print problem at once. CHLUMIWE® 2100 should move first when the main issue is substrate-contact wetting, spread, or cleaner laydown on paper, film, or coated labelstock. CHLUMIAG® 3501 deserves earlier review when the buyer needs a broader print-side handling, antiaanbaklaag, of downstream compatibility route across label inks, overprint varnishes, and nearby converting work. CHLUMIAF® 3062 belongs earlier when the system already looks directionally right but foam, entrained air, or circulation-side instability keeps undermining production or print quality.
That is the commercially useful split. This page is not another generic printing-ink overview. It is a narrower CHLUMICRYL® application page for buyers who already know the project is a label ink job and need a clearer first screen before requesting samples.
Why label inks deserve their own additive page
Longchang heeft al livepagina's voor flexographic ink additives, offset ink additives, inkjet ink additives, En waterborne overprint varnish additives. Those pages solve narrower process or varnish questions.
A label-ink project creates a different buyer question: is the first additive decision mainly about getting the ink to wet and spread on the label surface, about improving print-side handling and downstream compatibility, or about suppressing foam and trapped air during manufacture and use? That question sits above one single print process because label work can cross paper labelstock, film labelstock, coated facestocks, overprint steps, and downstream converting requirements.
The broader industry framing here is conservative. External printing-additive references commonly separate wetting behavior, surface-handling compatibility, and efficient defoaming as different additive jobs in printing inks. The product-specific facts below still stay tied to current Longchang-supported product pages.
Wat de huidige, door het bedrijf ondersteunde feiten al scheiden
- CHLUMIWE® 2100 is supported by Longchang for drukinkten, overdrukvernis, En inkjetinkten, with recommended dosage at 0,1% tot 1,0%, addition during grinding, stirring, of after production, optional solvent pre-dilution, and applicability across UV, oplosmiddel, En op water gebaseerde systemen.
- CHLUMIAG® 3501 is supported by Longchang as a meercomponenten gemodificeerd polysiloxaan that can be added at any stage and used across UV, oplosmiddel, En op water gebaseerde systemen. The current company-supported page directly lists drukinkten, inkjetinkten, overdrukvernis, lossingscoatings, En anti-sticking-agent use.
- CHLUMIAF® 3062 is the defoamer-first route. Longchang supports it for drukinkten met een aanbevolen dosering van 0,1% tot 0,5% of total formulation, broad UV, oplosmiddel, En op waterbasis 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 label inks without inventing unsupported application claims.
Snelle vergelijkingstabel: welke route verdient de eerste plek op het scherm?
| Buyer priority in label inks | Beste eerste route | Waarom het op de eerste plaats hoort | Hoofdobservatiepunt |
|---|---|---|---|
| Poor labelstock contact, weak spread, or a drawdown that still looks like a wetting-first problem on paper or film labels | CHLUMIWE® 2100 | Longchang directly lists printing inks and overprint varnishes on the product page and supports broad system fit with flexible addition timing | Keep the screening job focused on wetting and spread instead of expecting one additive to solve every post-print handling issue |
| Broader anti-sticking, print-side handling, or downstream varnish and release-oriented compatibility pressure | 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, letdown, 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® 2100 is the better first move
2100 should move to the front when the label-ink project still looks like a wetting and spread problem. This is often the cleaner first route when the label surface is not accepting the ink the way the team expects, the drawdown still shows weak first contact, or the lab needs a simpler benchmark before moving into broader print-side tradeoffs.
The current Longchang page gives 2100 a useful operating window for that job. It supports 0,1% tot 1,0% dosage, can be added during grinding, stirring, or after production, and can be diluted with water, alcohols, alkanes, and aromatics. The same page directly lists drukinkten en overdrukvernis among its application scenarios.
- Best first-screen use: labelstock wetting, spread, and initial laydown screening
- Dosage guidance: 0,1% tot 1,0% van de totale formulering
- Systeemgeschiktheid: UV-, oplosmiddel- en watergebaseerde systemen
- Commercial reason to shortlist it: it gives a cleaner first answer when the buyer still needs basic surface contact to improve before testing broader handling or foam-control routes
In short, 2100 is the better first move when the real question is still how the label ink meets the substrate.
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 antiaanbaklaag, release-oriented, of print-side compatibility path that can still sit naturally inside a label-ink branch.
The current Longchang page is clear here. 3501 is not only listed for drukinkten; it is also publicly positioned for inkjetinkten, overdrukvernis, lossingscoatings, En anti-sticking-agent use. It can be added at any stage and used across UV, oplosmiddel, En op water gebaseerde systemen.
- Best first-screen use: broader print-side handling questions, including anti-sticking, release-oriented, or varnish-adjacent workflows
- Addition logic: can be added at any stage or later
- Systeemgeschiktheid: UV-, oplosmiddel- en watergebaseerde systemen
- Commercial reason to shortlist it: it is the cleaner route when the buyer needs a wider label-converting compatibility path instead of only a wetting correction
That makes 3501 the better first move when the problem sits more in handling, downstream compatibility, or print-face surface behavior than in basic spread.
When CHLUMIAF® 3062 is the better first move
3062 should move first when the label-ink project already has a plausible wetting route but the system keeps failing because of foam, entrained air, of poor process stability. That is a different job from improving first contact or tuning print-side 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 polyether-modified polysiloxane defoamer for drukinkten, with a recommended dosage at 0,1% tot 0,5% of total formulation and applicability across UV, oplosmiddel, En op water gebaseerde systemen. 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 label-ink workflows
- Dosage guidance: 0,1% tot 0,5% van de totale formulering
- Systeemgeschiktheid: UV-, oplosmiddel- en watergebaseerde systemen
- 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.
Hoe kopers een keuze moeten maken voordat ze monsters aanvragen.
1. Start with the first visible bottleneck
If the label surface still is not accepting the ink cleanly, start with 2100. If the real issue is broader handling, anti-sticking, or downstream compatibility, move 3501 earlier. If the project is already being damaged by foam or trapped air, move 3062 up.
2. Keep the label construction visible
This page is intentionally broader than one press process because label work can move across coated paper, film, and nearby converting steps. That is why the first screen here is about label-ink decision pressure, not only one machine type.
3. Do not force a defoamer into a wetting job
If the buyer has not yet solved basic substrate 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
2100 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, een broader print-side compatibility routeen één defoamer-first route teach more than screening too many nearby additives at once.

FAQ
Which additive should I screen first if a label ink is not spreading cleanly?
Usually CHLUMIWE® 2100, because it is the cleaner wetting-first benchmark when the real problem is labelstock contact and spread.
When should 3501 move ahead of 2100?
3501 should move ahead when the ink already wets reasonably well but the project still needs a broader anti-sticking, print-side 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.
Can one of these additives solve every label-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, downstream handling, or foam control.
Need a faster shortlist for label inks?
If your team is stuck between substraatbevochtiging, print-side handling and downstream compatibility, En foam control, define the real first-screen job before requesting samples. That usually shows much faster whether CHLUMIWE® 2100, CHLUMIAG® 3501, or CHLUMIAF® 3062 deserves the first round.
