빠른 답변: 구매 담당자가 작업 중입니다 waterborne plastic topcoats usually get a better first shortlist when they separate three different finish-stage jobs instead of asking one additive to rescue every panel defect at once. Start with 슐루밀® 3345 when the topcoat still needs calmer wetting and leveling on the visible plastic finish. Move 클루미아그® 3501 forward when the topcoat already lays down directionally but the finished parts still need stronger anti-sticking and downstream handling control. Start with 클루미크릴® DF-D9904BR when the real visible blocker is microbubbles, foam carry-through, or pinholes in the water-based topcoat film.
This page stays inside the redirected 클로미크릴® 코팅 및 잉크 첨가제 direction and does ~ 아니다 fall back to the older photoinitiator cluster. It also is not a duplicate of Longchang’s already-live waterborne topcoat page, the broader waterborne plastic coatings page, or the narrower waterborne plastic clearcoats page. It answers a tighter B2B question: which additive deserves the first trial when a waterborne plastic topcoat still is not giving a clean, stable, handling-ready finish?
Why waterborne plastic topcoats deserve their own additive page
A waterborne plastic topcoat sits in a narrower buyer lane than either a broad waterborne topcoat article or a general plastic-coatings page. The finish layer is usually judged less by raw primer adhesion and more by how the visible film lays down, how the dried surface behaves in contact handling, 그리고 whether trapped air still survives into the final film read.
That creates a different first-screen question from a clearcoat page. A clearcoat buyer usually keeps transparency, crater sensitivity, and clean surface read at the center. A topcoat buyer often has to balance visible laydown on plastic, blocking or contact-mark risk after drying, 그리고 water-based air-release discipline at the same time. Those are not the same first screen, even when the same plastic part test panel shows more than one symptom.
General industry framing supports that split conservatively. Waterborne coatings on plastic parts often force buyers to think about substrate-sensitive wetting, finish appearance, stacked-part handling, and bubble cleanup together. The product-specific facts below still stay tied to current Longchang-supported product pages.
What the current company-supported evidence actually separates
- 슐루밀® 3345 롱창의 지원을 받습니다. polyether modified polysiloxane and positioned directly as a 습윤 및 평활성제. The current company page supports use across 수성, 용매 및 UV 시스템, with supported dosage at 0.1% ~ 1.0%. Longchang also supports flexible addition during grinding, stirring, 또는 after production, plus the practical note that co-solvents such as dipropylene glycol methyl ether can enhance the effect.
- 클루미아그® 3501 지원됩니다 다성분 변성 폴리실록산 route for UV, 용매 및 수성 시스템. The company-supported route keeps together anti-sticking-agent use, release-coating use, and broad finishing compatibility across 인쇄 잉크, 잉크젯 잉크, 스크린 인쇄 잉크, 그리고 오버프린트 바니시롱창 또한 지원합니다. addition at any stage or later, which matters when a finish project already is directionally acceptable but still needs handling cleanup.
- 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. Supported dosage is 0.1% ~ 1.0%, with the practical recommendation to incorporate by 고속 교반 or grinding and, when practical, through a co-solvent-first route for easier dispersion.
That is enough company-supported separation to build a real buyer-selection page without inventing unsupported product facts. External framing is used only conservatively for the general point that finish-stage plastic topcoats are often screened by laydown quality, post-dry contact behavior, and bubble control rather than by one generic additive story.

CHLUMILE® 3345가 더 나은 첫걸음이 될 때
3345 should move first when the waterborne plastic topcoat still needs calmer wetting and more even leveling. This is the cleaner route when the coating can already form a film, but the visible result still looks less uniform, less smooth, or less commercially ready than the buyer wants on finished plastic parts.
That distinction matters because plastic topcoat buyers often are not only solving substrate entry. They are solving how the finish reads on the visible part. Longchang’s product page is useful here because 3345 is positioned directly as a wetting and leveling agent and supports flexible process-stage addition.
3345번 도로를 먼저 선택하는 것이 일반적으로 더 나은 경우는 다음과 같습니다.
- the waterborne plastic topcoat still shows uneven laydown or rough visual flow-out,
- the team wants one first screen for both surface entry and calmer final-film formation,
- the project still is early enough to benefit from flexible addition timing, or
- the buyer needs a broader wetting-plus-leveling benchmark before moving into narrower handling or defoaming routes.
This is often the most useful first move when the finish is reaching the plastic surface, but not finishing cleanly enough.
When CHLUMIAG® 3501 is the better first move
3501 should move ahead first when the plastic topcoat already lays down directionally well enough, but the finished parts still need a stronger anti-sticking and downstream handling route. This is the cleaner first choice when the visible finish is no longer the whole problem and the project is being judged by what happens when coated plastic parts touch during movement, stacking, packing, or downstream assembly.
Longchang’s current product page keeps 3501 inside 달라붙지 않음 및 release-oriented use windows and supports broad finishing compatibility across inks and varnish-side work. That makes it commercially useful as a finish-handling route when the buyer question has shifted from film formation into surface contact behavior after drying.
3501 is usually the better first route when:
- the waterborne plastic topcoat already looks workable but coated parts still block or stick too easily in contact handling,
- the lab wants a more dedicated surface-release route than a broad leveling aid,
- the finish needs to stay open to wider coating-system comparisons later, or
- the buyer has moved beyond appearance cleanup and into downstream handling stability.
This is the stronger first move when the real commercial question is not only how the plastic finish looks but how the coated surface behaves after drying.
CHLUMICRYL® DF-D9904BR이 더 나은 첫 번째 선택일 때
DF-D9904BR deserves the earlier screen when the visible defect is still being driven by trapped air. This is the better route when the waterborne plastic topcoat already wets directionally enough to judge the film, but microbubbles, foam carry-through, or pinholes still distort the finish.
The current Longchang page is direct enough to make this a real finish-stage route. DF-D9904BR is supported for 수계 시스템 and positioned explicitly around microbubble and pinhole prevention. That makes it commercially useful when the finish complaint is not really about surface release or leveling anymore, but about air surviving into the dried film.
DF-D9904BR is usually the better first route when:
- the panel still shows fine bubble traces, pinholes, or persistent foam-related marks,
- the line already has directionally acceptable laydown but still cannot get a clean read on the final film,
- the process can respect the supported high-shear incorporation 및 co-solvent-first handling logic, or
- the buyer needs a direct answer on water-based air-release cleanup before changing the broader topcoat package.
This route is usually more useful than adding more surface-control material when the real blocker is still air trapped in the film.
구매자는 첫 번째 샘플 검토 전에 어떻게 선택해야 할까요?
1. Start with the first failure the customer can actually see
If the waterborne plastic topcoat still looks uneven, start with 3345. If the finish looks directionally acceptable but parts still stick or mark in contact, move 3501 forward. If the film still shows microbubbles or pinholes, start with DF-D9904BR.
2. Keep appearance logic separate from handling logic
Many finish projects collapse leveling and blocking into the same request. That usually makes the first sample round noisy. A panel that looks unsettled and a panel that handles poorly after drying are not necessarily asking for the same additive first.
3. Treat bubble cleanup as its own route
Microbubbles and pinholes are not just weaker versions of poor wetting. If trapped air still dominates the film, that needs its own decision path.
4. Keep this page distinct from the clearcoat route
The already-live waterborne plastic clearcoat page stays tighter around transparent-finish and crater-sensitive clear-film behavior. This topcoat page is broader around visible laydown, contact handling after drying, 그리고 water-based bubble cleanup on the finish layer.
5. Keep the first trial set small and honest
For many waterborne plastic topcoat projects, the cleanest first plan is one 3345 laydown route, 하나 3501 handling 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 my waterborne plastic topcoat still looks uneven after application?
Usually CHLUMILE® 3345, because Longchang directly positions it as a wetting and leveling agent with flexible addition timing across water-based systems.
When should 3501 move ahead of 3345?
3501 should move ahead when the finish already looks directionally acceptable and the bigger problem has shifted to anti-sticking, contact marking, or handling after drying.
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 high-shear, co-solvent-first incorporation route.
Is this page the same as the broader waterborne topcoat page?
No. The broader page still answers the stage-level selection question first. This new page is narrower and helps plastic-topcoat buyers decide whether the first bottleneck is visible laydown, post-dry handling, or water-based air release.
다음 단계
If your waterborne plastic topcoat project is stuck between uneven laydown, blocking or contact-mark risk, 그리고 microbubble carry-through, stop treating them as the same additive request. Start with the real bottleneck first. That usually makes the next CHLUMICRYL® sample decision faster and more commercially useful.
