빠른 답변: 구매 담당자가 작업 중입니다 UV screen varnishes usually get a cleaner shortlist when they stop treating every surface issue like one vague varnish problem and instead separate 서로 다른 세 가지 첫 화면 작업. 클루미아그® 2750 should move first when the real question is a reactive UV surface-control route, especially when the project overlaps with reverse-varnish logic or wants a route that becomes more permanently fixed at the cured surface. 클루마일® 3432 deserves the earlier screen when the varnish already belongs in the right UV family but the visible varnish face still needs better leveling, slip, and crater balance. CHLUMIAF® 3062 belongs earlier when the thicker screen-varnish film is being limited by foam, trapped air, or bubble-sensitive process instability.
That is the commercially useful split. This page is not another general screen-ink article, and it is not a duplicate of the already-live UV 오버프린트 바니시 또는 UV varnish surface-control pages. It is a new CHLUMICRYL® application page for buyers whose job is specifically a UV screen varnish 또는 screen-applied spot varnish route, where a heavier deposited UV varnish film has to cure, look commercially acceptable, and stay practical in downstream handling.
Why UV screen varnishes deserve their own additive page
UV screen varnish sits in a narrower buyer lane than either a general UV varnish page or a broader screen-ink page. In practice, screen-varnish work often adds a thicker film build, a stronger visual expectation around gloss and surface smoothness, and more pressure to avoid bubbles, craters, or unstable cured-surface behavior on decorative printed work. External industry framing around spot UV and packaging varnish also commonly separates surface appearance, blocking or handling pressure, 그리고 film defects such as bubbles or craters instead of treating them as one interchangeable additive question.
That makes UV screen varnish a real B2B application page, not filler. Buyers here are usually not looking for a broad chemistry lesson. They are trying to decide which additive route deserves the 첫 번째 샘플 라운드 in a finishing workflow where the varnish itself is the visible effect layer.
What the current company-supported evidence actually separates
- 클루미아그® 2750 sits in a reactive UV family that Longchang says contains 반응성 아크릴 작용기, is suitable for solvent-free UV radiation-curing systems, solvent-based UV coatings, and other acrylic-resin systems, and can 고분자 네트워크 구조로 가교 결합 so it stays more permanently fixed at the coating surface. Longchang also highlights 수준 측량, 표면 평활도, and specifically notes that 2750은 역광택 처리에 더 적합합니다.. The supported dosage is 0.1% ~ 3% of total formulation, and the current company page marks it as suitable for UV 및 용제 systems, not water-based systems.
- 클루마일® 3432 지원됩니다 폴리에테르 변성 폴리실록산 route with a recommended dosage of 0.05% ~ 1.0% of total formulation. Longchang supports addition at any stage, optional dilution with water, alcohols, alkanes, or aromatics, and applicability across UV, 용제, 그리고 수계 시스템. This makes it a practical print-face route when the buyer needs a narrower screen around leveling and surface balance rather than a reactive-UV-only decision.
- CHLUMIAF® 3062 롱창의 지원을 받습니다. 폴리에테르 변성 폴리실록산 defoamer for 인쇄 잉크, industrial coatings, and related systems, with a supported dosage of 0.1% ~ 0.5% for printing inks and applicability across UV, 용제, 그리고 수계 시스템. The current company page also warns that if solvent dilution is used, stability and defoaming performance should be tested first.
That is enough supported separation to build a real buyer page. The point is not to invent unsupported screen-varnish miracle claims. The point is to help the buyer choose the first better route based on what the UV screen varnish is actually failing to do.
간략 비교표: 어떤 경로가 먼저 화면에 나와야 할까요?
| Buyer priority in UV screen varnishes | 최적의 첫 번째 경로 | 왜 이것이 첫 번째에 있어야 하는가 | 주요 감시 지점 |
|---|---|---|---|
| Reactive UV surface fixation, reverse-varnish logic, or a cured-surface route that should become more permanently anchored in the film | 클루미아그® 2750 | Longchang directly supports reactive acrylic UV logic, crosslinking into the cured network, and a reverse-varnish fit | Keep the route inside reactive UV logic instead of treating it like a generic drop-in slip additive |
| Visible-face leveling, smoother laydown, slip, and crater-sensitive print-surface balance in the varnish film | 클루마일® 3432 | The supported route gives a flexible any-stage screen around leveling and broader surface balance across UV systems | Use it when the real first defect sits on the visible varnish face, not when trapped air is the primary failure |
| Foam, entrained air, or bubble cleanup in higher-build screen-varnish processing and letdown | CHLUMIAF® 3062 | Longchang directly supports it as a printing-ink defoamer with UV, solvent, and water-based applicability | If solvent dilution is used, screen solvent stability and defoaming performance first |
When CHLUMIAG® 2750 is the better first move
2750 deserves earlier review when the buyer wants the additive decision anchored in reactive UV chemistry rather than only in broad surface tuning. The current company-supported product page is useful here because it does not only talk about smoother appearance. It explicitly says the route contains reactive acrylic functionality 그리고 할 수 있습니다 고분자 네트워크로 가교결합, and it directly notes that 2750은 역광택 처리에 더 적합합니다..
That matters because some UV screen varnish programs are not mainly fighting a bubble or wetting problem. They are trying to control how the cured varnish surface behaves when the decorative varnish layer itself is part of the product value. This is especially relevant when the screen-applied UV layer is expected to hold a more deliberate surface effect than a lighter OPV route.
2750 is usually the better first route when:
- the project is firmly inside a UV radiation-curing system,
- 구매자는 원합니다 reactive surface-fixation route instead of a broader compatibility route,
- the UV screen varnish brief overlaps with 역광택 or a more deliberate cured-surface discipline, or
- surface smoothness matters, but the team still wants the decision anchored in reactive cured-film logic.
The watchpoint is clear. 2750 is strongest when the buyer really needs a reactive UV screen-varnish route, not when the actual first defect is obviously process-side bubbles or a simpler visible-face leveling problem.
When CHLUMILE® 3432 is the better first move
3432 should move first when the UV screen varnish already lives in the right chemistry family, but the visible varnish face still is not behaving well enough. This is the stronger first route when the buyer is staring at a film that looks rough, unstable, or crater-prone even though the system itself is directionally correct.
That distinction matters in screen-applied varnishes because the varnish layer is often expected to create a visible effect, not just a hidden functional coating. A thicker UV screen-varnish film makes it easier for buyers to notice surface unevenness, crater-sensitive breakup, or a slip and laydown balance that still feels commercially off.
3432 is usually the better first route when:
- the first complaint is still visible-face appearance, not only cured-film durability or process foam,
- the varnish reaches the surface but still does not lay down calmly,
- the buyer wants one route centered on leveling and crater balance before switching to a more chemistry-specific or process-specific fix, or
- the lab needs a more flexible UV-compatible benchmark for the print face itself.
This makes 3432 the cleaner first move when the real question is not merely which additive belongs somewhere in UV varnish, but which route should be screened first for the visible face of the screen-applied varnish film.
When CHLUMIAF® 3062 is the better first move
3062 becomes more relevant when the buyer is losing time to 거품, 혼입된 공기, 또는 bubbles that survive into the thicker varnish film. That is a different first job from reactive cured-surface control or visible-face leveling. In a screen-varnish workflow, it can also be one of the most expensive mistakes to ignore, because heavier film builds can make trapped-air defects harder to hide once the varnish cures.
Longchang’s current product page is commercially useful here because 3062 is not boxed into one narrow chemistry window. It is supported for 인쇄 잉크 with a dedicated dosage range and broad system applicability across UV, 용제, 그리고 수계 시스템. That gives buyers a practical route when the first problem is really gas management rather than reactive UV chemistry or visible-face leveling.
3062 is usually the better first route when:
- mixing, circulation, or letdown still is feeding bubbles into the varnish film,
- the heavier screen-varnish layer makes trapped-air defects too visible to ignore,
- the buyer needs a process-side cleanup route before screening more surface modifiers, or
- the team wants a UV-compatible defoamer benchmark without forcing the job back into a broader coating article.
The watchpoint is practical, not theoretical. If solvent dilution is part of the process plan, Longchang says the team should verify stability and defoaming performance 첫째.
구매자는 첫 번째 샘플 검토 전에 어떻게 선택해야 할까요?
1. Start with the real first bottleneck
If the UV screen varnish question is fundamentally a reactive cured-surface route, move 2750 up first. If the varnish face still needs a calmer visible laydown, start with 3432. If the film is being damaged by bubbles or trapped air, move 3062 earlier.
2. Separate visible-face control from process cleanup
One common mistake is to keep tuning leveling when the real failure is trapped air in a heavier film. The opposite mistake is to reach for a defoamer first when the process is stable enough and the actual problem is visible-face crater balance or surface smoothness.
3. Keep the page type honest
This page is not replacing the broader screen ink additives article, and it is not a duplicate of the UV 오버프린트 바니시 page. It is narrower. It is for buyers already inside the UV screen varnish lane who need a cleaner first-screen decision.
4. Use company-supported limits as shortlist boundaries
2750 is strongest when the selection should stay anchored in reactive UV logic. 3432 is strongest when the visible-face varnish layer needs leveling and crater balance. 3062 is strongest when the first problem is foam and trapped air. Those are real decision boundaries, not minor notes.
5. Keep the first round small
For many labs, the cleanest first screen is one 2750 reactive UV route, 하나 3432 visible-face leveling route그리고 하나 3062 air-release route. That usually teaches more than screening several near-neighbor additives without a clear hypothesis.

자주 묻는 질문
Which additive should I screen first for a UV screen varnish with reverse-varnish logic?
Usually CHLUMIAG® 2750, because Longchang directly supports reactive acrylic UV logic, crosslinking into the cured network, and says 2750 is more suitable for reverse varnish.
When should 3432 move ahead of 2750?
3432 should move ahead when the UV screen varnish already sits in the right chemistry family and the real problem is still the visible varnish face, especially leveling, surface smoothness, or crater-sensitive balance.
When does 3062 make more sense than the other two?
3062 makes more sense when the thicker varnish film is being limited by foam, entrained air, or bubble-sensitive process instability and the team needs to clean up the process side before judging further surface-control changes.
Is this page the same as the screen-ink additive page?
No. The screen-ink page is broader and centered on screen-printing inks. This page narrows the buyer question to UV screen varnishes, where the varnish itself is often the visible effect layer and thicker films make cured-surface and bubble control more important.
Can one of these additives solve every UV screen varnish 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 in reactive cured-surface control, visible-face leveling, or trapped-air cleanup.
Need a tighter UV screen-varnish shortlist?
팀이 다음과 같은 상황에 처해 있다면 반응성 UV 표면 고정, visible-face leveling and crater balance, 그리고 bubble cleanup in a thicker screen-varnish film, stop treating them as one vague additive request. Start with the real first bottleneck. That usually makes the next CHLUMICRYL® sample decision much faster.
