Schnelle Antwort: Käufer arbeiten an can coatings usually get a cleaner first shortlist when they separate three different jobs instead of asking one additive to solve every surface problem at once. CHLUMIFE® 3166 should move first when the main target is a breitere Oberflächenbilanzroute across wetting, smoothness, gloss, anti-blocking, and scratch support. CHLUMIAG® 3467 deserves earlier review when the system is more compatibility-sensitive and the first question is whether a leveling and anti-cratering route can clean up the film without narrowing the formulation window too quickly. CHLUMIFE® 3307X gehört früher, wenn die Beschichtung bereits zufriedenstellend abgeschieden ist, aber die Auch ausgehärtete Folien benötigen noch eine höhere Kratz- und Abriebfestigkeit. und Die Überlackierbarkeit ist weiterhin wichtig.
That is the commercially useful split. This page is not another broad coatings-additives overview. It is a narrower CHLUMICRYL® application page for buyers who already know the project is a metal-packaging or can-coating job and need a faster first screen.
Why can coatings deserve their own additive page
Longchang hat bereits Live-Seiten für CHLUMICRYL® Beschichtungs- und Druckfarbenadditive, Zusatzstoffe für die Spulenbeschichtung, anti-corrosion coating additives, Nivellierungsadditiveund kratzfeste Zusätze. Those pages solve broader buyer questions.
A can-coating project creates a narrower one: should the first additive screen focus on broad surface balance, compatibility-first defect control, or final-film scratch and recoat performance? That is a different decision from a general industrial-coating page because metal-packaging buyers often care about smooth laydown, crater control on metal surfaces, blocking or scuff risk during handling, and whether later coating or overprint steps still stay practical.
That broader industry framing is used here only as conservative application context. The product-specific facts below stay tied to current Longchang-supported product pages.
Was unterscheidet diese drei Routen?
- CHLUMIFE® 3166 wird von Longchang als ein Polyether-modifiziertes Polyorganosiloxan used to control surface tension, with supported gains around ausgezeichnetes Trockengefühl, Substratbenetzbarkeit, Oberflächenglätte, Kratzfestigkeit, Antiblockierung, Nivellierungund Glanzverbesserung. The page supports use in UV-, lösungsmittel- und wasserbasierte Systeme.
- CHLUMIAG® 3467 wird von Longchang als ein Mehrkomponenten-modifiziertes Polysiloxan that prioritizes Systemkompatibilität. Its current company-supported route includes Nivellierung, Antikrater, Substratbenetzung, and flexible use either as a direct coating additive or during polyurethane resin modification. The page supports use in UV-, lösungsmittel- und wasserbasierte Systeme.
- CHLUMIFE® 3307X ist die spezifischere cured-film scratch and abrasion route. Longchang explicitly supports it around improving Abriebfestigkeit und Kratzfestigkeit nach der Filmbildung, along with Oberflächenglätte, Nivellierungund ein Überlackierbarkeit zuerst position. Its current company page supports UV- und Lösungsmittelsysteme, not water-based systems.
That is enough separation to justify a real buyer-selection page instead of sending every can-coating team back to a generic additive hub.
Kurzvergleichstabelle: Welche Route verdient den ersten Bildschirm?
| Buyer priority in can coatings | Beste erste Route | Warum es an erster Stelle steht | Hauptbeobachtungspunkt |
|---|---|---|---|
| Broader surface balance across wetting, smoothness, gloss, anti-blocking, and scratch support | CHLUMIFE® 3166 | Longchang supports it as a broader surface-control route across UV, solvent, and water-based systems | May cause pinholes or whitening and may stabilize foam, so risk checks should stay visible early |
| Compatibility-first anti-cratering, leveling, and wetting control in a more defect-sensitive formulation | CHLUMIAG® 3467 | Longchang positions it around compatibility-first use, anti-cratering, and flexible direct-add or resin-modification routes | Feel is not its main strength when compared with more feel-led options |
| Cured film still scratches or abrades too easily and recoatability still matters | CHLUMIFE® 3307X | Longchang explicitly ties it to scratch and abrasion resistance after film formation with recoatability priority | Non-water-based only, and solvent pre-dilution is recommended before use |
Wann CHLUMIFE® 3166 der bessere erste Schritt ist
3166 should move first when the can-coating project is still balancing more than one surface KPI at once. Longchang’s current product page is clear that this route is not only about one narrow defect. It highlights ausgezeichnetes Trockengefühl, Substratbenetzbarkeit, Oberflächenglätte, Kratzfestigkeit, Antiblockierung, Nivellierungund Glanzverbesserung. The page supports a recommended dosage of 0.05% to 1.0% of total formulation and says it can be added at any stage of production, with optional solvent dilution for easier addition.
That makes 3166 commercially useful when the team is not only chasing crater cleanup or only post-cure durability. It is often the better first route when the buyer wants one broader benchmark that helps answer whether the can coating still needs stronger wetting, smoother laydown, safer anti-blocking balance, and better surface feel together.
- Systempassform: UV-, lösungsmittel- und wasserbasierte Systeme
- Hauptstärke: broader balance instead of one narrow function
- Wichtigste Vorsichtsmaßnahme: Longchang explicitly flags possible Nadellöcher, Aufhellungund ein schaumstabilisierende Wirkung, so defoamer planning may still be needed during testing
In short, 3166 is the cleaner first screen when the project needs a broad answer before the team narrows into a more specialized route.
Wann ist CHLUMIAG® 3467 der bessere erste Schritt?
3467 deserves earlier review when the formulation window looks more compatibility-sensitive and the first question is whether a leveling and anti-cratering route can solve the surface problem without forcing the lab into a less tolerant package too early. Longchang supports 3467 as a Mehrkomponenten-modifiziertes Polysiloxan and explicitly says the product Priorisiert die Systemkompatibilität.
The current company page also supports multiple practical routes. For coating modification, it can be added directly or diluted with a suitable solvent. For polyurethane modification, it can be added with the polyol during prepolymerization or added later. Longchang’s supported dosage windows are 0,05% bis 1% of the total formulation for solvent-based systems, 0,5% bis 5% of the resin amount for resin modification, and 0,5% bis 5% of the total formulation for water-based systems.
- Systempassform: UV-, lösungsmittel- und wasserbasierte Systeme
- Hauptstärke: compatibility-first route with anti-cratering, leveling, and wetting support
- Wichtigste Vorsichtsmaßnahme: the product page says its feel is slightly less refined, so it should not be the automatic first choice when premium hand feel is the main target
That makes 3467 a strong first screen when crater control, formulation tolerance, and practical addition flexibility matter more than a more feel-led route.
Wann CHLUMIFE® 3307X der bessere erste Schritt ist
3307X becomes more relevant when the can coating already lays down acceptably but the final cured film still marks, scratches, or abrades too easily. Longchang’s product page is explicit that this route is designed to improve Abriebfestigkeit und Kratzfestigkeit nach der FilmbildungDie gleiche Seite unterstützt auch Oberflächenglätte, Nivellierungund ein Überlackierbarkeit zuerst Position.
That creates a meaningful buyer split. Some can-coating projects do not fail first on wet-stage flow. They fail later when the coated metal surface still needs stronger damage resistance while keeping later processing practical. Longchang supports a recommended dosage of 0.1% to 1.0% of total formulation and says the product should be diluted to 12.5% with solvent vor Gebrauch.
- Systempassform: UV and solvent systems only
- Hauptstärke: cured-film scratch and abrasion route with recoatability priority
- Wichtigste Vorsichtsmaßnahme: it is not a water-based route, and solvent pre-dilution should be built into the test plan
So 3307X is the better first move when the buyer is judging the final film, not only the wet film.
Wie Käufer vor der Anforderung von Mustern auswählen sollten
1. Beginnen Sie mit der eigentlichen Phase des Scheiterns.
If the project still needs a broad answer across wetting, smoothness, blocking, and gloss, start with 3166. If the bigger risk is crater control and compatibility, move 3467 earlier. If the film looks acceptable at application but still fails under scratch or abrasion pressure, move 3307X up.
2. Systemgrenzen sichtbar halten
3166 and 3467 both sit inside Longchang’s supported UV, solvent, and water-based windows. 3307X does not. That alone helps keep the first shortlist disciplined.
3. Do not treat overlap as interchangeability
All three routes touch appearance or surface performance. That does not make them interchangeable. The supported first-screen logic is different for each one.
4. Use the watchpoint, not only the headline benefit
3166 brings pinhole, whitening, and foam-stabilization risk. 3467 prioritizes compatibility but not the best feel. 3307X needs solvent pre-dilution and belongs in non-water-based screening. Those practical notes often decide the better first sample more than the product family name.
5. Die erste Runde eng gestalten
For many can-coating teams, one breitere Oberflächenbilanzroute, eins compatibility-first anti-cratering routeund eins cured-film scratch route teach more than an overloaded first panel with too many partially overlapping additives.

FAQ
Which additive should I screen first if the can coating problem is still broad?
Usually CHLUMIFE® 3166, because Longchang supports it as a broader surface-control route across wettability, smoothness, anti-blocking, scratch support, leveling, and gloss.
When should 3467 move ahead of 3166?
3467 should move ahead when compatibility and anti-cratering pressure matter more than a broader feel-led package, or when the project needs the practical option of direct coating modification or resin-modification use.
Wann sollte 3307X die anderen beiden überholen?
3307X should move ahead when the coating already lays down acceptably but the cured film still needs stronger scratch or abrasion resistance and recoatability remains important.
Are these three products interchangeable in can coatings?
No. Their supported system windows, first-screen logic, and risk notes are different enough that buyers should not treat them as drop-in substitutes.
Need a faster shortlist for can coatings?
If your can-coating project is stuck between broader surface balance, compatibility-first crater controlund cured-film scratch resistance, define the real first-screen job before requesting samples. That usually shows much faster whether CHLUMIFE® 3166, CHLUMIAG® 3467, or CHLUMIFE® 3307X deserves the first round.
