Jawaban singkat: buyers comparing CHLUMIWE® 3280, CHLUMILE® 3432, Dan CHLUMIAG® 3501 should not treat them as three versions of the same silicone additive. 3280 should move first when the problem is still pembasahan substrat yang sulit, spread, atau pinhole-risk control on film, coated stock, or other harder-to-wet surfaces. 3432 belongs earlier when the substrate already wets reasonably well but the printed face still needs better penyamarataan, kelancaran, tergelincir, atau anti-cratering balance. 3501 becomes the cleaner first route when the buyer needs broader anti lengket, release-oriented handling, atau downstream compatibility across printing and finishing work.
That is the useful shortlist split. This page is not another broad packaging-format article. It is a tighter comparison page for buyers already inside the CHLUMICRYL® print branch and trying to decide which route deserves the first lab round.
Why this page is distinct from the already-live 2100 and print-application pages
Longchang already has live CHLUMICRYL® pages for flexographic inks, gravure inks, screen inks, offset inks, and several packaging-print branches. Longchang also already has a live shortlist at 2100 vs 3432 vs 3501 for broader ink wetting, print-face leveling, and anti-sticking screening.
This page answers a narrower buyer question: what if the wetting route itself needs to be tighter and more difficult-substrate-led than the broader 2100 benchmark? That is where 3280 earns its own page. The intent is different from another application article and different from the broader 2100 shortlist because the first lane here is not generic wetting. It is harder-surface wetting plus pinhole-risk and low-foam behavior.
What the current company-supported facts actually separate
- CHLUMIWE® 3280 is the difficult-substrate wetting route. Current Longchang-supported product information positions it as an organic silicone wetting agent and surfactant with direct suitability for screen inks, waterborne coating systems, and surface-tension-sensitive use. It supports 0.01% to 1.0% dosage, allows addition at any stage, can be diluted with water, and is described as non-foaming dengan pencegahan lubang kecil.
- CHLUMILE® 3432 is the print-face leveling routeLongchang mendukungnya dengan 0,05% hingga 1,0% dosage, any-stage addition, and use across UV, pelarut, Dan sistem berbasis air. The current product information and related Longchang-controlled application notes place it in tinta cetak, pernis cetak berlebih, and smoothness-led work where buyers need leveling, slip, anti-adhesion, anti-blocking, wetting, and anti-cratering support.
- CHLUMIAG® 3501 is the broader anti-sticking and handling route. Longchang supports it as a multi-component modified polysiloxane used across UV, pelarut, Dan sistem berbasis air, with addition possible at any stage or later. The current product page directly lists tinta cetak, tinta inkjet, tinta sablon, pernis cetak berlebih, lapisan pelepas, Dan anti-sticking-agent use.
That gives enough supported separation to build a real buyer shortlist. Outside research was used only for conservative framing that printing-ink additive selection often splits into surface entry and wetting, printed-face appearance control, Dan downstream handling compatibility, rather than one generic silicone story.

| Buyer priority | 3280 | 3432 | 3501 |
|---|---|---|---|
| Main first-screen job | Difficult-substrate wetting, spread, and pinhole-risk control | Print-face leveling, smoothness, slip, and anti-cratering balance | Broader anti-sticking, release-oriented handling, and downstream compatibility |
| Supported dosage | 0.01% to 1.0% | 0,05% hingga 1,0% | Current public page emphasizes stage flexibility more clearly than a visible dosage band in the summary used here |
| System window | Especially useful where screen-ink or waterborne surface sensitivity matters | UV, solvent, water-based | UV, solvent, water-based |
| Logika penambahan | Any stage, water dilution supported | Any stage, optional dilution when needed | Any stage or later addition |
| Best use when | The substrate still does not accept the ink or coating cleanly and low-foam wetting is the first bottleneck | The substrate already wets, but the printed face still lays down roughly, slips poorly, or shows crater-like surface defects | The buyer needs a broader print-side anti-sticking and compatibility route rather than only wetting or leveling correction |
| Titik pengawasan utama | Use it for the true wetting bottleneck, not as a catch-all replacement for broader handling work | Do not force it into a defoamer-first job when the issue is really surface appearance and print-face behavior | Do not use it as a substitute for a harder-surface wetting benchmark when first contact is still failing |
When CHLUMIWE® 3280 is the better first move
3280 should move first when the print surface itself is still resisting the formulation. This is the cleaner route when films, coated papers, smoother packaging stocks, or screen-print substrates still are not accepting the ink or coating evenly enough, or when the buyer also wants a non-foaming wetting route with pinhole-prevention value.
The current Longchang-supported product information gives several useful signals for this job:
- direct use in screen inks
- support for waterborne coating systems
- 0.01% to 1.0% recommended dosage
- addition at any stage
- dilution with air
- non-foaming behavior
- pencegahan lubang kecil
That makes 3280 the better first route when:
- the first failure is still weak spread or incomplete surface entry,
- the stock is harder to wet than a broader printing benchmark would suggest,
- the team wants to reduce wetting risk without adding a high-foam correction step, or
- surface defects are starting close to the wetting stage rather than later in printed-face handling.
In short, 3280 belongs first when the job still is a difficult-substrate wetting problem.
When CHLUMILE® 3432 is the better first move
3432 deserves earlier review when the surface already wets reasonably well, but the printed face still is not behaving properly. That usually means the team has moved beyond first contact and now needs better penyamarataan, kelancaran, tergelincir, anti-pemblokiran, atau anti-kawah balance.
Current Longchang-supported information makes 3432 a strong route for that stage. It is positioned with 0,05% hingga 1,0% dosage, any-stage addition, and applicability across UV, solvent, and water-based systems. Related Longchang-controlled application notes keep using it where buyers need smoother laydown, anti-adhesion, anti-blocking, lower stable foam, and more stable print-face appearance in inks and varnishes.
3432 is usually the better first route when:
- the ink already reaches the substrate but still looks rough, drags, or blocks,
- the team needs one route balancing surface appearance and handling on the printed face,
- wetting alone has already improved but crater-like or leveling-sensitive defects remain, or
- the buyer wants a cleaner print-face benchmark before stepping into broader anti-sticking compatibility work.
That makes 3432 the better first move when the real question is not will it wet? but will it lay down and handle cleanly after wetting?
When CHLUMIAG® 3501 is the better first move
3501 should move earlier when the project has already gone beyond a narrow wetting or leveling discussion and the buyer now needs a broader anti lengket, release-oriented, atau downstream compatibility route. This is often the cleaner choice when the surface already wets and lays down directionally well enough, but downstream converting, overprint-varnish contact, release-adjacent use, or general print-side handling still is not stable enough.
The current Longchang product page supports that broader position directly. 3501 is listed for tinta cetak, tinta inkjet, tinta sablon, pernis cetak berlebih, lapisan pelepas, Dan anti-sticking-agent use. It can be added at any stage or later and stays open across UV, solvent, and water-based systems.
3501 is usually the better first route when:
- the buyer needs a broader handling and compatibility route instead of only wetting or leveling correction,
- the first screening decision needs to stay commercially aligned with OPV, melepaskan, atau anti lengket questions,
- the printed face already looks directionally acceptable but downstream handling remains weak, or
- the team wants one route that can bridge several printing and finishing conversations.
So 3501 belongs first when the project is really asking about what happens after laydown, not only how the surface is first wetted.
How buyers should choose before the first sample round
1. Start with the first real bottleneck
If the surface still is not accepting the formulation cleanly, start with 3280. If the substrate wets but the printed face still lays down badly or shows crater-like defects, move 3432 up. If the problem has already shifted into broader anti-sticking and downstream handling, move 3501 up.
2. Keep difficult wetting separate from broader handling work
One common mistake is to keep testing broad anti-sticking or compatibility routes when the real failure is still first-contact wetting on a harder surface. Another is to keep tuning wetting when the project has already moved into printed-face leveling and slip. Separating those stages usually shortens the lab cycle.
3. Use the operating notes, not only the headline role
3280 has a low starting dosage window and low-foam, pinhole-prevention framing. 3432 has broad system fit with explicit smoothness and anti-cratering positioning. 3501 has the broadest handling and anti-sticking framing of the three. Those details are part of the selection logic, not minor side notes.
4. Keep the page type honest
This is not a catch-all “best additive for all inks” page. It is a product-comparison page for buyers already deciding between three specific CHLUMICRYL® routes. That narrower intent is why it can sit cleanly beside the broader application pages and the already-live 2100 comparison.

PERTANYAAN YANG SERING DIAJUKAN
Which product should I test first if the surface still is not wetting cleanly?
Usually CHLUMIWE® 3280, because it is the tighter difficult-substrate wetting route on this page and carries direct non-foaming and pinhole-prevention framing.
When should 3432 move ahead of 3280?
3432 should move ahead when the substrate already wets reasonably well and the real issue becomes print-face leveling, smoothness, slip, anti-blocking, or crater-like appearance control.
When should 3501 move ahead of the other two?
3501 should move ahead when the buyer needs a broader anti-sticking, release-oriented, or downstream compatibility route instead of only wetting or leveling correction.
Is this page replacing the live application pages for screen, gravure, or label inks?
No. Those pages still answer application-specific questions first. This page is narrower and serves the buyer who is already comparing these three additive routes.
Why not just use the broader 2100 comparison instead?
Use the broader 2100 comparison when the first wetting route can stay general. Use this page when the wetting route itself needs to be tighter and more difficult-substrate-led, especially when low-foam behavior and pinhole-risk matter earlier.
Need a tighter first shortlist?
Jika proyek Anda terjebak di antara pembasahan substrat yang sulit, printed-face leveling, Dan broader anti-sticking or handling compatibility, separate the bottleneck before requesting samples. That usually makes it much clearer whether CHLUMIWE® 3280, CHLUMILE® 3432, or CHLUMIAG® 3501 deserves the first trial.
