Hızlı cevap: alıcılar üzerinde çalışıyor waterborne appliance basecoats usually get a cleaner first shortlist when they stop treating every panel defect like one vague additive problem and instead separate three different jobs. CHLUMIWE® 3071 should move first when the real bottleneck is difficult-surface wetting and first-contact spread on smooth appliance panels or already-primed appliance substrates. CHLUMIAG® 3467 deserves the earlier screen when the basecoat still shows a compatibility-first crater, fisheye, or pullback problem. CHLUMIFE® 3166 is the cleaner first move when the basecoat already can form a usable film but still needs a stronger laydown, dry-feel, and smoother-surface route before clearcoat.
That is the commercially useful split. This page stays inside the CHLUMICRYL® coating-and-ink-additives direction and does Olumsuz drift back to the older photoinitiator cluster. It also is not a duplicate of Longchang’s already-live waterborne primer, waterborne topcoat, waterborne plastic basecoat, veya waterborne appliance clearcoat pages. It is a narrower waterborne appliance-basecoat buyer page for teams qualifying appearance-sensitive appliance panels where wetting, crater-sensitive compatibility, and laydown before clearcoat need to be separated early.
Why waterborne appliance basecoats deserve their own additive page
Waterborne appliance basecoats sit in a tighter buyer lane than a broad industrial or appliance-coating article. They are often judged not only on whether the film reaches the surface, but on whether the pigmented or appearance-setting layer looks commercially acceptable before clearcoat and leaves a stable enough surface for the next coating step. That creates a different first-screen question from either a primer page or a clearcoat page.
In practical formulation work, the first additive decision often needs to separate a difficult-surface wetting problem from a crater-sensitive compatibility problem, and both from a later laydown and surface-refinement problem before clearcoat. Those are not the same first screen, even when the same panel trial shows all three symptoms.
General industry framing supports that split. Surface modifiers and leveling additives in waterborne coatings are commonly used to improve substrate wetting, reduce cratering or poor leveling, and help produce a smoother, more uniform film. This page uses that outside framing only conservatively, while keeping product-level claims anchored 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 wetting route with low viscosity ve low surface tension, giving excellent spreadability, wetting, and penetration. The current company page also supports broader usefulness around flow, leveling, recoatability, and gloss retention. Supported dosage is 0.1% ile 1.0% arası, and the page notes that the product may have a foam-stabilizing effect on water-based systems.
- CHLUMIAG® 3467 is supported by Longchang as a çok bileşenli modifiye polisiloksan and a reactive leveling route that can be used across UV, çözücü, ve su bazlı sistemler. The current company-supported route keeps together leveling, krater karşıtı, yüzey ıslatma, and a clear note that it prioritizes sistem uyumluluğu. 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.
- CHLUMIFE® 3166 desteklenmektedir polieter modifiye edilmiş poliorganosiloksan için UV, çözücü, ve su bazlı sistemler. Longchang supports reduced surface tension, yüzey ıslatılabilirliği, yüzey pürüzsüzlüğü, çizilmeye karşı dayanıklılık, engelleme karşıtı, leveling, parlaklık iyileştirmesi, and especially mükemmel kuru hisÖnerilen doz şöyledir: 0.05% ile 1.0% arasında, with cautions around pinholes, whitening, and possible foam-stabilizing effects.
That is enough company-supported separation to build a real buyer page. The point is not to invent an appliance-only miracle additive. The point is to help a buyer choose the first better test route based on what the appliance basecoat is actually failing to do.

CHLUMIWE® 3071, ilk adım olarak daha iyi bir seçimdir.
3071 should move first when the appliance basecoat still struggles to enter the surface cleanly. This is the stronger first route when the visible problem starts as reluctant wetting, poor first-contact spread, or a panel read that suggests the film still is not getting a confident early grip on a smooth appliance-facing substrate or already-primed surface.
That matters because a waterborne appliance basecoat is often expected to lay down evenly enough for appearance evaluation and still leave a stable surface for clearcoat. If the film never reaches a clean first-contact state, later crater-cleanup or finish-refinement additives can be harder to judge honestly.
3071 is usually the better first route when:
- the basecoat still beads, hesitates, or spreads unevenly on smooth appliance-facing surfaces,
- the lab needs a first benchmark focused on surface entry before higher-level finish tuning,
- the project already knows the substrate or primer surface is difficult to wet consistently, or
- the buyer wants a direct water-based wetting route without jumping immediately into a broader compatibility package.
The watchpoint stays visible. Longchang also notes that 3071 may stabilize foam in water-based systems, so it is better treated as a wetting-first decision, not as a complete answer to every defect.
CHLUMIAG® 3467'nin ilk tercih olarak daha iyi olduğu durumlar
3467 should move ahead first when the basecoat can reach the surface, but still shows craters, fisheyes, pullback, or other signs that the real bottleneck is a compatibility-first leveling and anti-cratering problem. This route is stronger when the issue is not simply poor wetting, but unstable film formation after application begins.
That distinction matters in appliance basecoats because the appearance-setting middle layer is often what buyers judge before approving the next step. Longchang’s current product page is useful here because 3467 is not positioned only as a feel additive. The supported route keeps together leveling, krater karşıtı, yüzey ıslatma, ve compatibility-first logic.
3467 is usually the better first route when:
- the basecoat still shows fisheyes, pullback, or crater-sensitive breakup on appliance-facing panels,
- the formulator wants a compatibility-led surface-stability route before moving to final feel or gloss tuning,
- the pigmented layer still needs a cleaner read before clearcoat qualification, or
- the project is unstable enough that better feel alone would be the wrong first screen.
The watchpoint is also clear. Longchang says this route prioritizes sistem uyumluluğu, so it is most useful when the line still needs to stabilize the basecoat, not when the main job already has shifted to tactile refinement.
CHLUMIFE® 3166, ilk adım olarak daha iyi bir seçimdir.
3166 deserves the earlier screen when the basecoat already can wet and stay on the surface reasonably well, but the film still needs a better laydown, dry-feel, and smoother surface balance before clearcoat. This is the cleaner first path when the project is no longer fighting obvious wetting failure or crater breakup, but still does not like how the basecoat settles or reads before the next layer.
Longchang’s current product page keeps 3166 commercially useful here because it is not positioned only as a niche hand-feel additive. It is supported around yüzey pürüzsüzlüğü, dry feel, leveling, engelleme karşıtı, parlaklık iyileştirmesi, ve çizilmeye karşı dayanıklılık. That combination is useful when a buyer wants one route that can help the appliance basecoat calm down directionally before clearcoat without inventing unsupported appliance-specific claims.
3166 is usually the better first route when:
- the basecoat already reaches and stays on the surface well enough,
- crater and fisheye behavior are no longer the main blocker,
- the team still wants a smoother panel read or better dry feel before the next layer, or
- the lab needs a broader laydown benchmark before narrowing toward more specialized finish additives.
The watchpoint should stay visible. Longchang also warns that similar products may lead to pinholes, whitening, veya foam stabilization, so 3166 should be screened when the basecoat already is stable enough to judge those tradeoffs honestly.
How buyers should choose before the first sample round
1. Start with the real first failure in the basecoat
If the film still struggles to wet the surface, start with 3071. If the basecoat reaches the surface but still breaks into crater or fisheye behavior, move 3467 forward. If the layer already forms but still needs smoother laydown before clearcoat, start with 3166.
2. Keep wetting logic separate from crater logic
A basecoat that will not spread and a basecoat that spreads but then pulls back are not the same additive problem. Separating those routes early usually makes the first sample round cleaner.
3. Keep laydown refinement separate from defect rescue
Surface smoothness and dry feel before clearcoat are not just smaller versions of wetting rescue or crater rescue. If the basecoat still has basic surface-entry or compatibility problems, it can distort how the team reads every later additive.
4. Respect the system watchpoints
3071 may stabilize foam in water-based systems. 3467 prioritizes compatibility more than refined finish feel. 3166 may bring pinholes, whitening, or foam stabilization if the system is not ready. Those watchpoints are part of the selection logic, not a footnote.
5. Keep the first trial set small and honest
For many waterborne appliance-basecoat projects, the cleanest first plan is one 3071 wetting route, bir 3467 compatibility routeve bir 3166 laydown route. That usually teaches more than forcing several near-neighbor additives into the same first screen.

SSS
Which additive should I screen first if a waterborne appliance basecoat still will not wet the surface evenly?
Usually 3071, because Longchang supports it as a low-surface-tension wetting route with spreadability, wetting, and penetration that fit the first-contact problem more directly than a crater-only or feel-only route.
When should 3467 move ahead of 3071?
3467 should move ahead when the basecoat can already reach the surface but still shows crater-sensitive breakup, fisheyes, or pullback that read more like a compatibility and leveling problem than a simple wetting shortfall.
When does 3166 make more sense than the other two?
It makes more sense when the basecoat already forms acceptably and the main question has shifted into smoother laydown, dry feel, and a calmer surface read before clearcoat.
Is this page the same as the broader waterborne primer or appliance clearcoat pages?
No. Those pages answer adjacent stage questions. This page narrows the buyer question to the waterborne appliance-basecoat stage and separates surface entry, compatibility-first crater cleanup, and laydown before the next layer.
Can one of these additives solve every waterborne appliance basecoat 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, crater-sensitive compatibility, or final laydown before clearcoat.
Daha dar bir aday listesi mi gerekiyor?
If your waterborne appliance-basecoat project is stuck between poor surface wetting, crater-sensitive film instability, ve smoother laydown before clearcoat, stop treating them as the same additive request. Start with the real bottleneck. That usually makes the next CHLUMICRYL® sample decision faster and more commercially useful.
