Hızlı cevap: alıcılar karşılaştırıyor CHLUMIWE® 3071, CHLUMILE® 3345, ve CHLUMIAG® 3467 usually get a cleaner shortlist when they stop treating them as three near-identical silicone additives. CHLUMIWE® 3071 should move first when the real bottleneck is difficult-surface wetting, spread, and first-contact coverage. CHLUMILE® 3345 deserves earlier review when the film already reaches the substrate but still needs broader wetting-and-leveling cleanup. CHLUMIAG® 3467 belongs earlier when the complaint behaves more like a compatibility-first anti-cratering, fisheye, or pullback problem inside a broader coating package.
That is the commercially useful split. This page stays inside the redirected CHLUMICRYL® coating-and-ink-additives direction and does Olumsuz drift back to the older photoinitiator cluster. It also is not just a repeat of the broader CHLUMICRYL® Kaplama ve Mürekkep Katkıları, ıslatıcı katkı maddeleri, tesviye edici katkı maddeleri, veya coating fisheye pages. Those pages explain the families or the defect branch. This new page answers the tighter buyer question that comes after that: which one of these three supported routes deserves the first sample round?
Why this 3071 vs 3345 vs 3467 comparison deserves its own page
In practical formulation work, these three products often get pulled into the same conversation because all three touch surface behavior. That is exactly why buyers can lose time. A project with poor first-contact spread on metal or plastic should not start from the same first additive screen as a project where the film already reaches the surface but still looks visually unsettled. Neither of those should be confused with a crater-sensitive system that really needs a more compatibility-first route.
General industry framing supports that separation. Surface-additive troubleshooting often starts by asking whether the failure begins at substrate entry, at film laydown and leveling, or in a more formulation-sensitive crater / fisheye / pullback window. This page uses that outside framing only conservatively. The product-specific claims below stay tied to current Longchang-supported product pages.
What the current company-supported evidence actually separates
- CHLUMIWE® 3071 is supported by Longchang as a polieter modifiye polisiloksan with recommended dosage of 0.1% ile 1.0% arası. The current company page supports excellent spreadability, wetting, and penetration, with use across UV, çözücü, ve su bazlı sistemler. Longchang also notes a practical watchpoint: it may have a foam-stabilizing effect in water-based systems.
- CHLUMILE® 3345 desteklenmektedir polieter modifiye polisiloksan positioned directly as a ıslatıcı ve düzleştirici madde. The supported dosage is 0.1% ile 1.0% arası, the product page keeps it open across UV, çözücü, ve su bazlı sistemler, and Longchang supports flexible addition during grinding, stirring, veya after production. The company page also notes that suitable co-solvents can enhance the effect.
- CHLUMIAG® 3467 is supported by Longchang as a çok bileşenli modifiye polisiloksan with a more uyumluluk öncelikli route around leveling, krater karşıtı, ve yüzey ıslatma. Supported dosage is 0.05% ile 1.0% arasında of total formulation for solvent systems, 0.5% - 5% of resin amount for resin modification, and 0.5% - 5% of total formulation for water-based systems. Longchang also states that this route prioritizes sistem uyumluluğu, even if the feel is slightly less refined.
That is enough company-supported separation to build a real buyer-selection page. The goal here is not to declare one universal winner. The goal is to help a buyer choose the first better screening route based on what the coating or ink actually is failing to do.
Hızlı karşılaştırma tablosu: Hangi rota ilk ekranda yer almayı hak ediyor?
| Observed formulation problem | En iyi ilk rota | Neden ilk sırada yer alıyor? | Ana gözetleme noktası |
|---|---|---|---|
| The coating or ink still struggles with first-contact spread, difficult-surface coverage, or weak substrate entry | CHLUMIWE® 3071 | Longchang supports it directly around spreadability, wetting, penetration, and broad cross-system use | Water-based systems still need to watch for possible foam stabilization |
| The film already reaches the surface, but still needs calmer visible laydown and a broader wetting-plus-leveling route | CHLUMILE® 3345 | Longchang positions it directly as a wetting and leveling agent with flexible process-stage addition | Use it when the main issue is broader laydown cleanup, not when crater-sensitive compatibility is the real blocker |
| The defect behaves more like crater, fisheye, pullback, or compatibility-sensitive film instability inside the formulation | CHLUMIAG® 3467 | The supported route keeps together anti-cratering, leveling, wetting, and system-compatibility logic | Its supported logic prioritizes compatibility more than a more refined final feel |
CHLUMIWE® 3071, ilk adım olarak daha iyi bir seçimdir.
3071 should move first when the project still is failing at surface entry. This is the stronger first route when the coating or ink still beads, hesitates, or spreads unevenly on plastic, metal, coated stock, or another difficult surface. If the liquid does not reach the substrate correctly, later-leveling discussions can become noisy because the film never had a fair first-contact start.
That supported logic is commercially useful because Longchang does not position 3071 only as a vague silicone aid. The current product page keeps together spreadability, wetting, ve penetration, while keeping the route open across UV, çözücü, ve su bazlı sistemler.
- En iyi ilk ekran kullanımı: difficult-surface wetting and first-contact spread
- Desteklenen dozaj: Toplam formülasyonun 0,1% ila 1,0%'si
- Başlıca güçlü yönü: one direct route for surface entry before broader laydown tuning
- Başlıca uyarı: water-based systems should still screen for possible foam stabilization
In short, 3071 is the better first move when the panel or print still suggests a coverage problem before a finish problem.
CHLUMILE® 3345, ilk tercih olarak daha iyi bir seçimdir.
3345 should move ahead first when the film can already reach the surface, but still does not lay down calmly enough. This is the stronger route when the buyer no longer needs a pure first-contact wetting answer and instead needs a broader wetting-and-leveling cleanup path for visible film formation.
That distinction matters because many labs collapse 3071 and 3345 into the same shortlist too early. The supported product logic says they should not be treated the same. 3345 is framed directly as a ıslatıcı ve düzleştirici madde, and Longchang supports a flexible addition window during grinding, stirring, or after production. That makes it commercially useful when the film already enters the surface directionally but still needs a calmer final read.
- En iyi ilk ekran kullanımı: broader wetting-plus-leveling cleanup after surface entry is already directionally acceptable
- Desteklenen dozaj: Toplam formülasyonun 0,1% ila 1,0%'si
- Başlıca güçlü yönü: a more balanced route for surface wetting and visible laydown together
- Main practical note: Longchang says suitable co-solvents can enhance the effect
So 3345 is the better first move when the issue has shifted from getting onto the surface için forming a smoother, calmer film on it.
CHLUMIAG® 3467'nin ilk tercih olarak daha iyi olduğu durumlar
3467 deserves the earlier screen when the complaint reads more like a compatibility-sensitive crater or fisheye problem than a simple spreading problem. This is the better first route when the coating or ink already reaches the surface but still shows craters, pullback, fisheyes, or a more unstable laydown pattern that points to a formulation-sensitive anti-cratering job.
Longchang’s current product page is especially useful here because 3467 is not positioned only as a feel additive. The supported route keeps together leveling, krater karşıtı, yüzey ıslatma, ve sistem uyumluluğu. That is why it belongs in a different first-screen lane from 3071 and 3345.
- En iyi ilk ekran kullanımı: crater-sensitive and compatibility-first screening
- Desteklenen dozaj: 0.05% to 1.0% of total formulation for solvent systems, with broader supported ranges for resin modification and water-based systems
- Başlıca güçlü yönü: one route that already combines anti-cratering, wetting, and compatibility logic
- Başlıca uyarı: Longchang says this route prioritizes compatibility, so finish feel is not the only lens to judge it by
This is usually the stronger first move when the defect pattern says the system needs stability and crater cleanup, not just better spread or a calmer finish.
How buyers should choose between 3071, 3345, and 3467 before requesting samples
1. Start with the real first failure
If the material still will not spread or cover the substrate correctly, start with 3071. If it spreads but still looks uneven or visually unsettled, start with 3345. If it already spreads yet still breaks into crater or fisheye behavior, move 3467 forward first.
2. Keep wetting logic separate from leveling logic
A coating that will not enter the surface and a coating that enters but still levels poorly are not asking the same question. Keeping those routes separate usually makes the first sample round much cleaner.
3. Keep compatibility-first crater rescue separate from both
Crater-sensitive pullback or fisheye behavior is not just a slightly worse leveling problem. If the formulation still looks compatibility-sensitive, 3467 belongs in its own first screen.
4. Respect the product watchpoints
3071 may stabilize foam in water-based systems. 3345 gains practical flexibility from its broad addition window and co-solvent support. 3467 should be judged through its compatibility-first logic, not only by final feel. Those watchpoints are part of the commercial selection path.
5. İlk ekranı kısa tutun.
For many coatings and inks, one 3071 wetting route, bir 3345 wetting-and-leveling routeve bir 3467 compatibility-first route teaches more than a crowded first panel full of overlapping silicone choices.

SSS
Which additive should I screen first if the coating still will not spread on metal or plastic?
Usually CHLUMIWE® 3071, because Longchang supports it directly around spreadability, wetting, and penetration for difficult-surface entry across UV, solvent, and water-based systems.
When should 3345 move ahead of 3071?
3345 should move ahead when the film already reaches the substrate directionally and the bigger issue has become calmer visible laydown rather than pure first-contact spread.
When does 3467 make more sense than the other two?
It makes more sense when the defect behaves more like crater, fisheye, or pullback instability and the formulation needs a more compatibility-first anti-cratering route instead of only better wetting or broader leveling cleanup.
Can I treat these three products as direct substitutes?
No. Their supported first-screen logic is different enough that buyers should not treat them as interchangeable without a tighter problem definition.
Is this page only for one coating system?
No. The supported product pages keep all three routes open across multiple system windows, but the correct first choice still depends on whether the failure starts at surface entry, broader laydown, or compatibility-sensitive crater control.
Daha dar bir aday listesi mi gerekiyor?
Eğer projeniz bir iki aşama arasında sıkışıp kaldıysa difficult-surface wetting, broader wetting-and-leveling cleanup, ve compatibility-first anti-cratering, define the real first failure before requesting samples. That usually shows much faster whether 3071, 3345, or 3467 deserves the first round.
