Jawaban singkat: pembeli sedang mengerjakan waterborne plastic basecoats usually get a cleaner shortlist when they stop treating every defect like a generic waterborne-coating problem and instead separate three different jobs. CHLUMIWE® 3071 should move first when the real bottleneck is difficult-substrate wetting and first-contact spread on plastic. 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 can already form a workable film but still needs a better laydown, dry-feel, and recoat-ready surface balance before clearcoat.
This is the commercially useful split. This page is not another broad plastic-coatings overview, and it is not a duplicate of the already-live waterborne plastic coatings, waterborne plastic primers, atau waterborne plastic clearcoats pages. It is a new substrate-plus-stage CHLUMICRYL® page for buyers whose project is specifically inside the waterborne plastic basecoat window, where a pigmented or appearance-sensitive middle layer must wet the plastic surface, stay stable through application, and leave a cleaner surface for the next coating step.
Why waterborne plastic basecoats deserve their own additive page
Waterborne plastic basecoats sit in a narrower buyer lane than a broad plastic-coating article. They are usually judged not only on whether the film reaches the substrate, but on whether the pigmented layer looks commercially acceptable before clearcoat and whether it leaves a stable surface for the next step. That creates a different screening order from either a primer page or a clearcoat page.
In practical work, the first additive decision often needs to separate a substrate-entry problem from a crater-sensitive compatibility problem, and both from a later laydown and recoat-readiness problem. Those are not the same first screen, even when the same plastic panel shows all three symptoms.
External industry framing supports that waterborne basecoat troubleshooting often revolves around wetting, crater / fisheye control, Dan film laydown before the next layer. This page uses that general framing 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 polisiloksan yang dimodifikasi polieter wetting route for UV, pelarut, Dan sistem berbasis air. The current supported dosage is 0,1% hingga 1,0% of total formulation. Longchang supports it around pembasahan substrat, low surface tension, and broad coating-system usability, while also warning that it may have a foam-stabilizing effect on water-based systems.
- CHLUMIAG® 3467 is supported by Longchang as a polisiloksan termodifikasi multi-komponen dan sebuah reactive leveling route that can be used across UV, pelarut, Dan sistem berbasis air. The current company-supported page gives it 0,05% hingga 1,0% of total formulation for solvent systems, 0,5% hingga 5% of resin amount for resin modification, and 0,5% hingga 5% of total formulation for water-based systems. The supported route includes penyamarataan, anti-kawah, pembasahan substrat, and a clear note that it prioritizes system compatibility over a more refined feel.
- CHLUMIFE® 3166 didukung sebagai polyether-modified polyorganosiloxane untuk UV, pelarut, Dan sistem berbasis air. Longchang supports reduced surface tension, keterbasahan substrat, kehalusan permukaan, tahan gores, anti-pemblokiran, penyamarataan, gloss improvement, and especially sensasi kering yang sangat baikDosis yang disarankan adalah 0,05% hingga 1,0%, with cautions around pinholes, whitening, and possible foam-stabilizing effects.
That is enough supported separation to build a real buyer page. The point is not to invent a plastic-basecoat miracle additive. The point is to help a buyer choose the first better test route based on what the basecoat is actually failing to do.
Tabel perbandingan singkat: rute mana yang layak ditampilkan di layar pertama?
| Buyer priority in waterborne plastic basecoats | Rute pertama terbaik | Mengapa ini harus didahulukan? | Titik pengawasan utama |
|---|---|---|---|
| Poor substrate entry, hesitant wetting, or uneven first-contact spread on plastic | CHLUMIWE® 3071 | Longchang supports it as a broad wetting route with low surface tension and water-based applicability | Water-based systems still need to watch for possible foam stabilization |
| Crater-sensitive breakup, fisheyes, pullback, or a pigmented basecoat that still reads like a compatibility problem | CHLUMIAG® 3467 | The supported route keeps together leveling, anti-cratering, substrate wetting, and compatibility-first logic | Its current product logic prioritizes compatibility more than refined feel, so it should be screened when stability comes before touch or finish tuning |
| The basecoat already forms, but still needs smoother laydown, cleaner surface feel, and a better recoat-ready read before clearcoat | CHLUMIFE® 3166 | Longchang supports it for smoothness, dry feel, leveling, anti-blocking, gloss support, and scratch balance across water-based systems | Qualification still needs to watch for pinholes, whitening, or foam stabilization |
When CHLUMIWE® 3071 is the better first move
3071 should move first when the basecoat still struggles to enter the plastic surface cleanly. This is the stronger first route when the visible problem starts as reluctant wetting, poor initial spread, or a surface read that suggests the film still is not getting a confident first grip on the substrate.
That matters because a waterborne plastic basecoat is often expected to lay down evenly enough to support color development and still leave a stable interface for the next coating layer. If the film never reaches a clean first-contact state, later crater-cleanup or feel additives can be harder to judge honestly.
3071 is usually the better first route when:
- the basecoat still beads, hesitates, or breaks during early wetting on plastic,
- the lab needs a first benchmark focused on substrate entry before higher-level finish tuning,
- the project already knows the plastic surface is difficult to wet consistently, or
- the buyer wants a simple first route that is directly tied to water-based wetting support.
The watchpoint stays visible. Longchang also warns 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 application-side defect.
When CHLUMIAG® 3467 is the better first move
3467 should move ahead first when the basecoat can reach the plastic 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 substrate entry, but unstable film formation after application begins.
That distinction matters in pigmented basecoats. Once color and solids are in the layer, crater-sensitive surface defects can make it difficult to read whether the rest of the package is acceptable. Longchang’s current product page is useful here because 3467 is not positioned only as a feel additive. The supported route keeps together penyamarataan, anti-kawah, pembasahan substrat, Dan compatibility-first logic.
3467 is usually the better first route when:
- the basecoat still shows fisheyes, pullback, or crater-sensitive breakup on plastic,
- the formulator wants a compatibility-led surface-stability route before moving to touch or scratch tuning,
- the pigmented layer needs a cleaner read before clearcoat qualification, or
- the project still is unstable enough that better feel alone would be the wrong first screen.
The watchpoint is also clear. Longchang says this route prioritizes system compatibility, so it is useful when the line still needs to stabilize the basecoat, not when the main job already has shifted to final tactile refinement.
Kapan CHLUMIFE® 3166 merupakan langkah pertama yang lebih baik?
3166 deserves the earlier screen when the basecoat already can wet and stay on the plastic surface reasonably well, but the film still needs a better laydown, dry-feel, and recoat-ready surface balance. This is the cleaner first path when the project is no longer fighting basic substrate entry or obvious 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 narrow touch additive. It is supported around kehalusan permukaan, dry feel, penyamarataan, anti-pemblokiran, gloss improvement, Dan tahan gores. That combination is useful when a buyer wants one route that can help the basecoat surface calm down directionally before clearcoat without inventing unsupported plastic-specific claims.
3166 is usually the better first route when:
- the basecoat already reaches and stays on the plastic surface well enough,
- crater and fisheye behavior are no longer the main blocker,
- the team still wants a smoother surface read or better dry-feel before the next layer, or
- the lab needs a broader recoat-ready 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, atau 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 plastic 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 two routes early usually makes the first sample round cleaner.
3. Keep recoat-readiness separate from defect rescue
Surface smoothness, dry feel, and laydown 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 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 plastic-basecoat projects, the cleanest first plan is one 3071 wetting route, satu 3467 compatibility route, dan satu 3166 laydown route. That usually teaches more than forcing several near-neighbor additives into the same first screen.

PERTANYAAN YANG SERING DIAJUKAN
Which additive should I screen first if my waterborne plastic basecoat still will not wet the substrate evenly?
Usually 3071, because Longchang supports it as a wetting route with low surface tension and water-based applicability, which fits the first-contact spread 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 cleaner recoat-ready surface before clearcoat.
Is this page the same as the broader waterborne plastic coatings page?
No. The broader page covers a wider branch. This page narrows the buyer question to the waterborne plastic-basecoat stage and separates substrate entry, compatibility-first crater cleanup, and laydown before the next layer.
Can one of these additives solve every waterborne plastic 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.
Need a tighter shortlist?
If your waterborne plastic-basecoat project is stuck between poor plastic wetting, crater-sensitive film instability, Dan recoat-ready 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.
