Risposta rapida: acquirenti confrontano CHLUMIWE® 2100, CHLUMIWE® 3280e CHLUMIAG® 3501 per packaging and printing inks Non bisogna considerarli come additivi al silicone intercambiabili. CHLUMIWE® 2100 appartiene prima quando il primo collo di bottiglia è broad substrate wetting, spread, or cleaner laydown on film, plastic, or general packaging-print surfaces. CHLUMIWE® 3280 should move ahead when the project is more specifically about bagnatura di substrati difficili, coated or smoother paper surfaces, or a screen-ink style wetting job where lower surface tension and stronger first contact matter more than a broad compatibility story. CHLUMIAG® 3501 è la prima via più pulita quando la pressione reale è broader anti-sticking, release-oriented handling, O compatibilità lato stampa rather than only substrate wetting.
That is the commercially useful split. This page is not another general label page or another broad wetting-additive overview. It is a pagina di confronto for buyers who are already down to three realistic CHLUMICRYL® routes and need to decide which one deserves the first sample round.
Perché questo confronto merita una pagina dedicata
Longchang already has live CHLUMICRYL® application pages for label inks, shrink sleeve inks, paper cup inks, folding carton inks, blister packaging inks, and broader process pages such as flexographic inks, gravure inks, screen inkse inchiostri a getto d'inchiostro. Those pages answer application or process questions first.
Questa pagina risponde a una domanda B2B più specifica e pratica: if the shortlist is already down to 2100, 3280, and 3501, which one should be tested first, and why? That is a different search intent from a broad application article. It is product-selection intent inside the CHLUMICRYL® branch.
It also helps reduce overlap in a mature packaging-and-print cluster. Instead of publishing another near-duplicate packaging-substrate page, this comparison gives buyers a cleaner decision tool that can route back into several live application pages and core product pages.
Ciò che le prove supportate dall'azienda effettivamente distinguono
I dati presenti sulla pagina del prodotto forniscono già una suddivisione utile:
- CHLUMIWE® 2100 è posizionato come un multi-component modified polydimethylsiloxane wetting route with Da 0,1% a 1,0% recommended dosage, addition during grinding, stirring, O after production, dilution with acqua, alcoli, alcani e aromaticie applicabilità in Sistemi a base di raggi UV, solventi e acqua. The current Longchang page also places it in the printing inks / packaging coatings lane and describes it for broader packaging-surface wetting and acrylic-resin coating adhesion improvement.
- CHLUMIWE® 3280 è posizionato come un polisilossano modificato con polieteri wetting route with 0.2% to 3.0% recommended dosage, addition during grinding, stirring, O after production, the same broad dilution window, and applicability in Sistemi a base di raggi UV, solventi e acqua. Longchang’s public product page also explicitly ties it to inchiostri per serigrafia, Rivestimenti a polimerizzazione UV, excellent substrate wetting, prevenzione dei fori stenopeicie non-foaming behavior in water-based systems.
- CHLUMIAG® 3501 è posizionato come un polisilossano modificato multicomponente that can be added at any stage of production or later and used in Sistemi a base di raggi UV, solventi e acqua. The current Longchang page directly lists inchiostri da stampa, inchiostri a getto d'inchiostro, inchiostri per serigrafia, vernici di sovrastampa, rivestimenti antiaderentie anti-sticking-agent use.
That is enough company-supported separation to build a real shortlist without inventing unsupported performance claims for specific end uses.
Tabella comparativa rapida: quando ogni percorso merita la prima schermata
| Priorità dell'acquirente | 2100 | 3280 | 3501 |
|---|---|---|---|
| Principale ruolo di primo schermo | Broad wetting, spread, and packaging-surface contact | Difficult-substrate wetting, coated-stock wetting, or stronger screen-ink style first contact | Broader anti-sticking, release-oriented handling, and print-side compatibility |
| Dosaggio supportato | Da 0,1% a 1,0% | 0.2% to 3.0% | Current public page highlights stage flexibility rather than a dosage band in the excerpted operating section |
| Finestra di sistema | UV, solvente, a base d'acqua | UV, solvente, a base d'acqua | UV, solvente, a base d'acqua |
| Logica di addizione | Macinazione, miscelazione o post-produzione | Macinazione, miscelazione o post-produzione | Any stage or later addition |
| Da utilizzare preferibilmente quando | The ink still needs a broad wetting benchmark across film, plastic, or general packaging surfaces | The project is more specifically about difficult substrates, coated stock, or a stronger first-contact wetting route | The ink already wets reasonably well but still needs broader anti-sticking, release, or downstream handling compatibility |
| Punto di osservazione principale | Do not use it as a vague catch-all if the real issue is anti-sticking or release behavior after printing | Do not treat it as simply the same route as 2100 with a different number, because its public positioning is more specific around difficult-substrate and screen-ink wetting | Do not use it as a substitute for a true wetting-first decision when the visible failure is still initial spread and substrate contact |
When CHLUMIWE® 2100 is the better first move
2100 should move first when the packaging or printing project still looks like a broad wetting and spread problem. This is often the cleaner benchmark when the surface may be filmic, plastic, or otherwise packaging-oriented, but the team is not yet at the point where it needs a more specialized difficult-substrate route or a broader anti-sticking route.
Longchang’s current public product page gives 2100 a practical operating window for that job. It supports Da 0,1% a 1,0% dosage, flexible addition during grinding, stirring, or after production, and dilution with acqua, alcoli, alcani e aromatici. The same page also places it in the printing inks / packaging coatings lane and points toward broader packaging-surface wetting and adhesion-improvement use.
2100 is usually the better first route when:
- il progetto si estende film, plastic, or mixed packaging-print surfaces rather than one very specific difficult stock,
- the team still needs to confirm that the real bottleneck is substrate contact and spread,
- the buyer wants a more general wetting screen before moving into narrower screen-ink or coated-stock discussions, or
- the application may later branch into several packaging or print routes and needs a broader first benchmark.
In short, 2100 is the more flexible first move when the decision is still how broadly the ink wets the target surface family.
When CHLUMIWE® 3280 is the better first move
3280 deserves earlier review when the project no longer looks like a general wetting question. It becomes the cleaner route when the buyer needs a more difficult-substrate, coated-stock, O screen-ink style wetting benchmark.
Longchang’s public page is more specific here than with a generic wetting additive. 3280 is positioned as a silicone wetting agent e agente bagnante per inchiostro serigrafico, and the excerpted product content also emphasizes excellent substrate wetting, prevenzione dei fori stenopeici, improved leveling, excellent resin miscibilitye non-foaming behavior in water-based systems. The supported dosage window is broader at 0.2% to 3.0%.
3280 is usually the better first route when:
- the coating or ink is running on coated paperboard, smoother stock, or another harder-to-wet substrate,
- the team wants a route that is publicly tied more directly to inchiostri per serigrafia or UV-curable wetting work,
- the first question is not general spread but whether a more aggressive or more specifically positioned wetting route is needed, or
- the water-based project wants a wetting benchmark that is explicitly described as non-foaming on the current company page.
So 3280 is not just another version of 2100. It is the more logical first screen when the buyer already knows the surface is more demanding or more specific than a broad packaging-wetting problem.
When CHLUMIAG® 3501 is the better first move
3501 should move to the front when the project is no longer only about wetting. It becomes the stronger route when the ink already lays down reasonably well, but the buyer still needs a broader antiaderente, release-oriented, O compatibilità lato stampa sentiero.
The current Longchang page makes that broader positioning unusually clear. 3501 is directly listed for inchiostri da stampa, inchiostri a getto d'inchiostro, inchiostri per serigrafia, vernici di sovrastampa, rivestimenti antiaderentie anti-sticking-agent use. It can also be added at any stage or later and stays open across Sistemi a base di raggi UV, solventi e acqua.
3501 is usually the better first route when:
- the printed surface already wets acceptably, but the project still has stacking, handling, release, or rub-sensitive compatibility pressure,
- the buyer wants one route that can sit credibly across inks, OPV, release-coating, and anti-sticking conversations,
- the lab is closer to a finished-film handling problem than to a basic substrate-contact problem, or
- the first screening decision needs to stay commercially aligned with downstream varnish or release-oriented use.
That makes 3501 the better first move when the real question is not will the ink wet the surface? but will the printed surface behave properly after laydown?
Why 3062 is not on this page
Some buyers may expect a defoamer route in every printing-ink shortlist because many live CHLUMICRYL® application pages use CHLUMIAF® 3062 as the foam-control route. That would be the wrong structure for this comparison.
This page is intentionally about a narrower decision: two wetting routes versus one broader anti-sticking and print-side compatibility route. If the project is clearly failing because of foam or air release rather than surface contact or finished-surface handling, the better path is to move into the live defoamer selection page or one of the application pages where 3062 is already the explicit third route.
That keeps this page from cannibalizing the existing ink-application pages and makes the product-comparison intent much clearer.
Come dovrebbero scegliere gli acquirenti prima del primo giro di campioni
1. Decide whether the failure is broad wetting or more specific difficult-substrate wetting
If the team still needs a broad packaging-surface wetting benchmark, start with 2100. If the substrate is already clearly more difficult, smoother, coated, or closer to a screen-ink style wetting problem, move 3280 earlier.
2. Keep finished-surface handling separate from first-contact wetting
One of the easiest evaluation mistakes is to keep testing wetting agents when the printed film already wets well enough, but the real failure has moved into anti-sticking, release, or downstream handling compatibility. That is when 3501 deserves the first screen instead.
3. Use the supported addition logic, not only the headline positioning
2100 and 3280 can both be added during grinding, stirring, or after production and share broad dilution flexibility. 3501 can be added at any stage or later. That process-fit difference is part of the comparison, not a minor technical footnote.
4. Do not compare dosage ranges out of context
2100 and 3280 both have public dosage guidance, but their supported positioning is still different. The goal is not to pick whichever number range looks broader. The goal is to match the additive to the first real job.
5. Mantieni onesto il tipo di pagina
This is not a catch-all “best additive for inks” page. It is a shortlist article for buyers already comparing three specific CHLUMICRYL® routes. That narrower comparison intent is exactly why it can coexist cleanly with the broader application pages.

FAQ
Which product should I test first if the project still needs a broad wetting benchmark for packaging or printing surfaces?
Start with CHLUMIWE® 2100. It is the cleaner broad-wetting route when the real problem is still general spread and substrate contact across film, plastic, or packaging-print surfaces.
When should 3280 move ahead of 2100?
3280 should move ahead when the substrate already looks more difficult, smoother, coated, or more like a screen-ink wetting problem than a general packaging-wetting problem.
When should 3501 move ahead of either 2100 or 3280?
3501 should move ahead when the ink already wets reasonably well, but the project still needs broader anti-sticking, release-oriented, or print-side handling compatibility.
Is this page replacing the existing packaging-ink application pages?
No. The application pages stay useful because they answer process or end-use questions first. This page is narrower and serves the buyer who is already comparing these three specific additive routes.
Why is a defoamer not part of this shortlist?
Because this article is intentionally focused on choosing between two wetting routes and one broader print-side compatibility route. If foam control is the real bottleneck, the better path is a dedicated defoamer decision instead.
Hai bisogno di una prima lista di candidati più ristretta?
If your packaging or printing ink project is stuck between broad film wetting, difficult-substrate first contacte broader anti-sticking or handling compatibility, stop testing these three products as if they solve the same first problem. Separate the real bottleneck first. That usually makes the next CHLUMICRYL® sample decision much faster.
