Jawaban singkat: pembeli memilih additives for paper varnishes usually get a faster first shortlist when they separate three different additive jobs instead of asking one product to solve every finishing problem at once. CHLUMIWE® 2100 should move first when the main issue is paper-surface wetting, spread, or cleaner first contact on coated or harder-to-wet paper. CHLUMILE® 3432 deserves earlier review when the buyer needs a clearer visible-face leveling dan surface-smoothness route in the varnish film. CHLUMIAG® 3501 belongs earlier when the varnish already lays down directionally well enough, but the line still needs a stronger anti lengket, sheet-handling, atau downstream converting compatibility route.
That is the commercially useful split. This page is intentionally narrower than a broad overprint-varnish article. It is a paper-varnish application page for buyers who already know the job is on paper or paperboard and need a cleaner first screen before requesting samples.
Why paper varnishes deserve their own additive page
Longchang sudah memiliki halaman aktif untuk UV overprint varnish additives, waterborne overprint varnish additives, and nearby paper-packaging ink routes such as paper bag ink additives dan corrugated box ink additives. Those pages answer broader chemistry or printing-format questions.
A paper-varnish project creates a different buyer question: is the first additive decision mainly about getting the varnish to wet the paper surface cleanly, about improving the visible smoothness of the varnish film, or about reducing sticking and handling pressure after drying and stacking? That is a distinct paper-finishing question because paper varnishes often sit close to coated paper, paperboard, printed sheets, and post-varnish stacking or converting pressure where the finish still has to stay workable.
The broader industry framing here is conservative. External paper-finishing references commonly separate pembasahan substrat, leveling and surface appearance, Dan blocking or handling behavior as different additive jobs in varnish formulation. The product-specific facts below stay tied to current Longchang-supported product pages.
Apa yang sudah dipisahkan oleh fakta-fakta yang didukung perusahaan saat ini?
- CHLUMIWE® 2100 is supported by Longchang as a multi-component modified polydimethylsiloxane wetting route with recommended dosage of 0,1% hingga 1,0%, addition during grinding, stirring, atau after production, optional pre-dilution with water, alcohols, alkanes, or aromatics, and applicability across UV, pelarut, Dan sistem berbasis air. The current company page also places it in tinta cetak, pernis cetak berlebih, Dan tinta inkjet.
- CHLUMILE® 3432 is supported by Longchang as a polyether-modified polysiloxane leveling agent with recommended dosage of 0,05% hingga 1,0%, any-stage addition, and applicability across UV, pelarut, Dan sistem berbasis air. The current company-supported application list places it in tinta cetak, packaging coatings, pernis cetak berlebih, and nearby finish-film routes.
- CHLUMIAG® 3501 is supported by Longchang as a polisiloksan termodifikasi multi-komponen that can be added at any stage or later and used across UV, pelarut, Dan sistem berbasis air. The current product page directly lists tinta cetak, tinta inkjet, pernis cetak berlebih, lapisan pelepas, Dan anti-sticking-agent use.
That is enough product-level separation to build a real paper-varnish shortlist without inventing unsupported printability, food-contact, or regulatory claims.
Tabel perbandingan singkat: rute mana yang layak ditampilkan di layar pertama?
| Buyer priority in paper varnishes | Rute pertama terbaik | Mengapa ini harus didahulukan? | Titik pengawasan utama |
|---|---|---|---|
| Poor paper-surface contact, weak spread, or a drawdown that still looks like a wetting-first problem | CHLUMIWE® 2100 | Longchang directly supports it for overprint-varnish and print-side use with a clear dosage window and flexible addition timing | Keep the first screen focused on wetting and spread instead of expecting one additive to solve later handling pressure |
| Visible unevenness, rough laydown, or a finish-face that still needs a cleaner leveling route | CHLUMILE® 3432 | The current company page clearly places it in printing inks, packaging coatings, and overprint varnishes with a dedicated leveling role | Because the job is appearance-led, test the film with the actual paper surface and varnish build rather than assuming one drawdown answers every sheet grade |
| Stacking pressure, anti-sticking concerns, or downstream converting compatibility after varnishing | CHLUMIAG® 3501 | The product page directly combines overprint-varnish use with release-coating and anti-sticking positioning | Define the actual KPI first, such as sheet separation, handling feel, or broader downstream compatibility, so the lab result stays interpretable |
When CHLUMIWE® 2100 is the better first move
2100 should move to the front when the paper-varnish project still looks like a wetting and spread problem. This is often the cleaner first route when coated paper, denser paperboard, or a smoother printed paper surface is not accepting the varnish the way the team expects, the drawdown still shows weak first contact, or the lab needs a simpler benchmark before moving into broader finish-face and handling tradeoffs.
The current Longchang page gives 2100 a useful operating window for that job. It supports 0,1% hingga 1,0% dosage, can be added during grinding, stirring, or after production, and can be diluted with air, alcohols, alkanes, atau aromatics. The same page directly lists pernis cetak berlebih among its application scenarios.
- Best first-screen use: paper-surface wetting, spread, and initial film-entry screening
- Dosage guidance: 0,1% hingga 1,0% dari total formulasi
- System fit: Sistem berbasis UV, pelarut, dan air.
- Commercial reason to shortlist it: it gives a cleaner first answer when the buyer still needs basic paper entry to improve before testing narrower leveling or anti-sticking routes
In short, 2100 is the better first move when the real question is still how the varnish meets the paper surface.
When CHLUMILE® 3432 is the better first move
3432 deserves earlier review when the project is no longer only about first contact. It is the stronger route when the buyer needs a clearer visible-face leveling dan surface-smoothness path for the varnish film. This is especially relevant when the drawdown already wets directionally well enough, but the finished paper face still looks less even than the buyer wants.
The current Longchang page is clear here. 3432 is positioned as a leveling agent, can be added at any stage, and is supported across UV, pelarut, Dan sistem berbasis air. The same public application list places it in tinta cetak, packaging coatings, Dan pernis cetak berlebih, which makes it commercially sensible for paper-varnish screening.
- Best first-screen use: visible smoothness, leveling, and finish-face cleanup in the paper-varnish film
- Dosage guidance: 0,05% hingga 1,0% dari total formulasi
- Addition logic: any-stage addition
- Commercial reason to shortlist it: it is the cleaner route when the buyer needs a more appearance-led answer than a broad wetting route can give
That makes 3432 the better first move when the real issue is less about paper entry and more about how the varnish surface settles and looks.
When CHLUMIAG® 3501 is the better first move
3501 belongs earlier when the paper-varnish project has started to shift out of visible laydown trouble and into handling trouble after drying or stacking. The current Longchang page is unusually clear about the application spread here. 3501 is positioned for pernis cetak berlebih, lapisan pelepas, Dan anti-sticking-agent use, while still keeping broad UV, solvent, and water-based system relevance.
That makes 3501 the cleaner first route when the varnish already lays down directionally well enough, but the project still has sticking, sheet-to-sheet contact, atau downstream converting compatibility pressure that a pure wetting or leveling route will not answer cleanly.
- Best first-screen use: anti-sticking, release-oriented handling, and downstream paper-stack compatibility
- Addition logic: can be added at any stage or later
- System fit: Sistem berbasis UV, pelarut, dan air.
- Main caution: define the actual handling KPI before screening so the result is not confused with a pure leveling improvement
So 3501 is the better first move when the project is being limited by finished-surface handling, not by missed paper entry or visible roughness alone.
Bagaimana pembeli sebaiknya memilih sebelum meminta sampel?
1. Start with the first visible bottleneck
If the paper surface still is not accepting the varnish cleanly, start with 2100. If the real issue is visible-face smoothness and leveling, move 3432 earlier. If the finish already looks directionally right but the line still has anti-sticking or stacking pressure, move 3501 up.
2. Keep paper-surface behavior separate from post-dry handling
Paper varnish development often drifts into vague language like “surface problem” even when the real job is changing. Wetting belongs earlier when the film is still entering the surface poorly. Leveling belongs earlier when the film enters but still settles unevenly. Anti-sticking belongs earlier when the finish looks better but still causes handling pressure after drying.
3. Use the application lane as a shortcut
2100 is easier to defend when the project brief still sounds like paper entry and spread. 3432 is easier to defend when the language is about visible-face smoothness. 3501 is easier to defend when the production complaint already includes sticking, contact, or downstream handling compatibility.
4. Do not use anti-sticking as a lazy catch-all
3501 is attractive because the application list is broad. That is useful, but it can also blur the first sample round if the team has not decided whether the real KPI is sheet separation, release behavior, or visible smoothness. Keep the first screen focused.
5. Keep the first shortlist short
For many buyers, one paper-entry route, satu visible-leveling route, dan satu anti-sticking route teach more than a crowded first trial full of partially overlapping additives.

PERTANYAAN YANG SERING DIAJUKAN
Which additive should I screen first if a paper varnish is not spreading cleanly?
Usually CHLUMIWE® 2100, because it is the cleaner wetting-first benchmark when the real problem is paper-surface entry and spread.
When should 3432 move ahead of 2100?
3432 should move ahead when the varnish already wets reasonably well but the visible finish still needs a more dedicated leveling route.
When should 3501 move ahead of both 2100 and 3432?
3501 should move ahead when the varnish film already looks directionally acceptable, but the project still has anti-sticking, sheet-handling, or downstream converting pressure that a pure wetting or leveling route will not answer well.
Does this page make regulatory or food-contact claims for paper packaging?
No. This page stays focused on additive-selection logic for paper-varnish workflows. Any food-contact review, migration work, or substrate-specific compliance qualification needs separate formulation and regulatory validation.
Can one of these additives solve every paper-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 at paper entry, visible leveling, or post-dry handling.
Need a faster shortlist for paper varnishes?
If your team is stuck between paper-surface wetting, visible-face leveling, Dan anti-sticking handling, define the real first-screen job before requesting samples. That usually shows much faster whether CHLUMIWE® 2100, CHLUMILE® 3432, or CHLUMIAG® 3501 deserves the first round.
