빠른 답변: 구매 담당자가 작업 중입니다 waterborne wood primers usually get a cleaner first shortlist when they stop treating every early wood-coating 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 timber, veneer, or wood-based board surfaces. 클루미아그® 3467 deserves the earlier screen when the primer still shows a compatibility-first crater, fisheye, or pullback problem. 클루미크릴® DF-D9904BR is the cleaner first move when the primer already can reach the surface but still is carrying microbubbles, foam carry-through, or pinholes that block an honest film read before topcoat.
That is the commercially useful split. This page stays inside the CHLUMICRYL® coating-and-ink-additives direction and does ~ 아니다 drift back to the older photoinitiator cluster. It also is not a duplicate of Longchang’s already-live 수성 목재 코팅제, waterborne wood sealer, 또는 wood varnish pages. It is a narrower waterborne wood-primer buyer page for teams that need to stabilize the primer layer before the finish system moves into the next coating step.
Why waterborne wood primers deserve their own additive page
A waterborne wood primer sits in a tighter decision lane than a broad wood-coating article. The buyer is usually not asking for a general explanation of wood finishes anymore. The project already is inside the primer stage, and the practical question is which additive deserves the first sample round when the primer still is not wetting cleanly, is breaking into crater-like defects, or is trapping enough air to corrupt the surface read before the next layer.
That creates a different selection problem from the already-live waterborne wood sealer page. A sealer-stage page is earlier and more porous-entry focused. A varnish or topcoat page is later and more finish-surface focused. A primer page sits between them. In normal formulation work, the first additive decision often needs to separate a difficult-surface wetting problem from a compatibility-first crater and leveling problem, and both from a true water-based microbubble and pinhole problem. Those are not the same first screen, even when the same drawdown shows all three symptoms.
The general industry framing here is conservative. Wood-primer programs commonly are judged first by surface entry, film stability, 그리고 air-release discipline before the topcoat gets a fair chance. This page uses that outside framing only lightly while keeping product-level claims anchored to current Longchang-supported product pages.
What the current company-supported evidence actually separates
- CHLUMIWE® 3071 롱창의 지원을 받습니다. 폴리에테르 변성 폴리실록산 wetting route with excellent spreadability, wetting, and penetration. The current company page supports a recommended dosage of 0.1% ~ 1.0%, use across UV, 용매 및 수성 시스템, and notes that it may have a foam-stabilizing effect in water-based systems. That makes it the cleaner first route when the wood primer still is not entering the surface honestly enough to judge later-stage appearance.
- 클루미아그® 3467 롱창의 지원을 받습니다. 다성분 변성 폴리실록산 that can be used across UV, 용매 및 수성 시스템. The current company-supported route keeps together 수준 측량, 반분화구, 기판 습윤, and a clear note that it 시스템 호환성을 우선시합니다.. Supported dosage is 0.05% ~ 1.0% of total formulation for solvent systems, 0.5%에서 5%까지 of resin amount for resin modification, and 0.5%에서 5%까지 of total formulation for water-based systems.
- 클루미크릴® DF-D9904BR 지원됩니다 polyether modified polysiloxane compound, silica-free, for 수계 시스템. Longchang directly positions it to prevent microbubbles and pinholes in the coating film of water-based coatings and inks. The supported dosage range is 0.1% ~ 1.0%, and the product page recommends co-solvent-first, high-shear incorporation instead of treating it as a casual late after-add shortcut.
That is enough company-supported separation to build a real buyer page. The point is not to invent a wood-only miracle additive. The point is to help a buyer choose the first better test route based on what the waterborne wood primer actually is failing to do.
간략 비교표: 어떤 경로가 먼저 화면에 나와야 할까요?
| Buyer priority in waterborne wood primers | 최적의 첫 번째 경로 | 왜 이것이 첫 번째에 있어야 하는가 | 주요 감시 지점 |
|---|---|---|---|
| Poor wetting, hesitant spread, or weak first-contact laydown on wood, veneer, or board surfaces | CHLUMIWE® 3071 | Longchang supports it as a low-surface-tension wetting route with spreadability, wetting, and penetration across water-based systems | Water-based systems still need to watch for possible foam stabilization |
| Crater-sensitive breakup, fisheyes, or pullback that still read like a compatibility problem inside the primer | 클루미아그® 3467 | The supported route keeps together leveling, anti-cratering, substrate wetting, and compatibility-first logic | Its current product logic prioritizes compatibility more than refined finish feel |
| The primer already reaches the surface, but trapped air still creates microbubbles or pinholes before topcoat | 클루미크릴® DF-D9904BR | Longchang directly positions it to prevent microbubbles and pinholes in water-based coating films | It is not a casual late after-add, and the recommended co-solvent plus high-shear route should be respected |
CHLUMIWE® 3071이 더 나은 첫걸음이 될 때
3071 should move first when the waterborne wood primer still struggles at first contact. This is the stronger first route when the visible problem starts as reluctant wetting, weak spread, or a drawdown read that suggests the primer still is not getting a confident early grip on the wood surface.
That matters because the primer layer is supposed to create a more stable base for the next coating step. If the film never reaches a clean first-contact state, later crater-cleanup or air-release routes can become harder to judge honestly.
- 첫 화면 사용에 가장 적합한 방법: difficult-surface wetting and first-contact spread
- 권장 복용량: 총 제형의 0.1% ~ 1.0%
- 주요 강점: one direct wetting route that already carries spreadability and penetration logic
- 주요 주의사항: Longchang notes a possible foam-stabilizing effect in water-based systems
In short, 3071 is the better first move when the wood primer still needs a cleaner surface-entry benchmark before the formulator decides whether the bigger issue is compatibility or air release.
CHLUMIAG® 3467이 더 나은 첫 번째 선택일 때
3467 should move ahead first when the primer 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 wood primers because the primer layer often decides whether the next coat later will be read as a true finish problem or just an inherited base-layer instability problem. Longchang’s current product page is useful here because 3467 is not positioned only as a feel additive. The supported route keeps together 수준 측량, 반분화구, 기판 습윤, 그리고 compatibility-first logic.
- 첫 화면 사용에 가장 적합한 방법: crater-sensitive and compatibility-led primer screening
- Water-based dosage guidance: 0.5% to 5% of total formulation on the current company page
- 주요 강점: one route that already combines anti-cratering, wetting, and system-compatibility logic
- 주요 주의사항: Longchang says this route prioritizes compatibility, so it is best screened when stability comes before finish feel
So 3467 is the better first move when the wood primer still needs a compatibility-first cleanup route before the project moves into a topcoat-facing discussion.
CHLUMICRYL® DF-D9904BR이 더 나은 첫 번째 선택일 때
DF-D9904BR should move ahead first when the waterborne wood primer is losing the fight to microbubbles, foam carry-through, or pinholes. In those cases, better wetting or broader compatibility usually will not clean up the panel enough to judge the rest of the package honestly.
Longchang’s product page is direct here. DF-D9904BR is supported specifically to prevent microbubbles and pinholes in the coating film of water-based coatings and inks, and it comes with a process note that matters commercially: the product should enter through a co-solvent step and be added under high shear rather than being treated as a late shortcut.
- 첫 화면 사용에 가장 적합한 방법: persistent microbubbles and pinholes in waterborne wood primers
- 복용량 안내: 총 제형의 0.1% ~ 1.0%
- 준비 규칙: use the supported co-solvent-first, high-shear route
- Main reason to shortlist it: it solves a different first problem from wetting or compatibility-first leveling routes
This is the stronger first move when the visible primer defect is being limited by air management, not by a missing wetting route or a broader anti-cratering route.
구매자가 샘플을 요청하기 전에 선택해야 할 사항
1. Start with the real first failure in the primer
If the film still struggles to wet the surface, start with 3071. If the primer reaches the surface but still breaks into crater or fisheye behavior, move 3467 forward. If the layer already forms but trapped air still is corrupting the panel read, start with DF-D9904BR.
2. Keep wetting logic separate from compatibility logic
A primer that will not spread and a primer 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 air-release cleanup separate from both surface routes
Microbubble and pinhole control are not just smaller versions of wetting rescue or crater rescue. If trapped air is still in the primer film, 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. DF-D9904BR should not be treated as a late after-add shortcut. Those watchpoints are part of the selection logic, not a footnote.
5. Keep the first trial set small and honest
For many waterborne wood-primer projects, the cleanest first plan is one 3071 wetting route, 하나 3467 compatibility route그리고 하나 DF-D9904BR bubble-control route. That usually teaches more than forcing several near-neighbor additives into the same opening screen.

자주 묻는 질문
Which additive should I screen first if a waterborne wood primer 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 bubble-only route.
When should 3467 move ahead of 3071?
3467 should move ahead when the primer 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 DF-D9904BR make more sense than the other two?
It makes more sense when microbubbles, foam carry-through, or pinholes still dominate the visible defect pattern and the process can follow the recommended co-solvent-first, high-shear addition route.
Is this page the same as the waterborne wood sealer page?
No. The sealer page still answers the earlier sealing-stage question first. This new page is narrower and helps wood-finish buyers choose between difficult-surface wetting, compatibility-first crater cleanup, and water-based bubble control at the primer stage before the next coat.
Need a tighter shortlist?
If your waterborne wood-primer project is stuck between poor surface wetting, crater-sensitive film instability, 그리고 microbubble carry-through, 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.
