Réponse rapide : acheteurs travaillant sur low-surface-energy films usually get to a better first shortlist when they stop asking one additive to solve every film-surface problem at once and instead separate three different jobs. CHLUMIWE® 3071 should move first when the project needs a broad coating-side wetting and spread route dans les systèmes à base d'UV, de solvants ou d'eau. CHLUMIWE® 2100 deserves the earlier screen when the real bottleneck is difficult-film wetting in packaging inks or other film-facing print routes where very low surface tension matters early. FS-D8975BR is the cleaner first move when ordinary wetting routes are no longer enough and the job has become a stronger solvent-based UV surface-control problem around anti-cratering, orange peel, slip, or tougher spray-flow behavior.
That is the commercially useful split. This page stays inside the redirected CHLUMICRYL® Additifs pour revêtements et encres direction and does pas drift back to the older photoinitiator cluster. It is also not a duplicate of Longchang’s already-live additifs mouillants page or fluorine surfactants page. Those are broader branch pages. This page answers a narrower buyer question: which additive route deserves the first trial when the target surface is a low-surface-energy film and the formulation still is not behaving honestly on that film face?
Why low-surface-energy films deserve their own additive page
Low-surface-energy film work often looks simple until it reaches the actual substrate. In conservative general-industry framing, film-facing systems such as polyolefin-style packaging films and other difficult plastic-film surfaces often challenge wetting more than metal, mineral, or already-absorbent surfaces do. A drawdown can look directionally acceptable on one panel and still fail commercially when the real target film shows beading, pullback, weak edge coverage, or an unstable print or coating face.
That is why a film-specific buyer page is useful. The first additive decision often needs to separate broad coating wetting from film-print wetting, and both from a later stronger fluorine-surfactant escalation route when ordinary organosilicone wetting still is not enough. Those are related decisions, but they are not the same first screen.
This page uses outside industry framing only conservatively. The product-level facts below stay tied to current Longchang-supported product pages.
What the current company-supported evidence already separates
- CHLUMIWE® 3071 is supported by Longchang as a polysiloxane modifié par un polyéther avec low surface tension, suitability across UV, solvantet systèmes à base d'eau, and supported benefit language around spreadability, mouillageet penetration. The current company page supports a recommended dosage of 0,1% à 1,0% and flags a possible foam-stabilizing effect in water-based systems.
- CHLUMIWE® 2100 is supported by Longchang as a multi-component modified polydimethylsiloxane route with surface tension below 25 mN/m, adéquation à UV, solvantet systèmes à base d'eau, and a direct product-application path inside printing inks and packaging coatings. The current page supports a recommended dosage of 0,1% à 1,0% and says that with a small amount added it will ne produit pas de mousse stable lors d'une dispersion à grande vitesse.
- FS-D8975BR is supported by Longchang as a fluorocarbon copolymer solution pour polymérisation UV à base de solvant. The current company-supported route keeps together bonne compatibilité avec le vernis, bon nivellement des ondes longues, prévention de la peau d'orange, excellente capacité anti-cratérisation, adéquation à pulvérisation à grande échelle, and a recommendation range of 0,05% à 0,8%. The product recommendation block also supports strong glisser plus meaningful dynamic and static surface-tension control.
That is enough supported separation to build a real buyer page. The goal is not to pretend that every low-surface-energy film project wants the same additive family. The goal is to help buyers choose the first better screening route based on what the film-facing system actually is failing to do.
Tableau comparatif rapide : quel itinéraire mérite la première place ?
| Observed low-surface-energy film situation | Meilleur premier itinéraire | Pourquoi cela devrait être la première chose à faire | Point de surveillance principal |
|---|---|---|---|
| The coating still struggles with broad first-contact wetting, spread, or clean coverage on difficult film surfaces across multiple system types | CHLUMIWE® 3071 | Longchang supports it directly around low surface tension, spreadability, wetting, and broad UV, solvent, and water-based system fit | Water-based systems still need to watch for possible foam stabilization |
| The main pressure sits in packaging inks or other film-facing print routes where very low surface tension and difficult-substrate entry matter first | CHLUMIWE® 2100 | The current Longchang route directly supports printing inks and packaging coatings, very low surface tension, and difficult-substrate use | Use it when the real first problem is film entry, not when the job already has become a fluorine-level crater or spray-flow problem |
| Ordinary wetting routes already have been screened and the project now needs stronger solvent-UV surface control for crater pressure, orange peel, slip, or tougher flow control | FS-D8975BR | Longchang supports it as a fluorocarbon route for solvent-based UV cure with anti-cratering, long-wave leveling, and stronger surface-response control | It is not a broad water-based or packaging-ink wetting route, and it should not be mistaken for a defoamer |
Quand CHLUMIWE® 3071 est le meilleur premier choix
3071 should move first when the buyer still needs a broad wetting benchmark for low-surface-energy film work. This is the cleaner route when the system still is failing at the first-contact stage and the team wants one practical wetting-and-spread screen that already fits UV, solvantet water-based development paths.
That matters because many film-facing coating projects are still in the stage of proving whether the surface can be entered cleanly at all. If the first coating film still beads, retreats, or spreads unevenly, it becomes harder to judge whether later defect-control or slip-control changes actually helped. Longchang’s current product page is useful here because 3071 is not positioned only as a narrow niche additive. It is supported around spreadability, mouillage, penetration, and broader surface-tension reduction across a wide system window.
3071 usually is the better first route when:
- the system still shows obvious surface-entry hesitation on difficult plastic-film faces,
- l'acheteur veut un cross-system wetting benchmark before narrowing the chemistry window,
- the line is more coating-led than packaging-print-led, or
- the team still needs a practical first answer before moving toward stronger fluorine-surfactant work.
The supported watchpoint also matters. Longchang notes that 3071 may stabilize foam in water-based systems, so it is best treated as a wetting-first decision, not as a zero-tradeoff fix.
When CHLUMIWE® 2100 is the better first move
2100 deserves earlier attention when the low-surface-energy film project is behaving more like a film-print or packaging-coating route than a broad industrial coating screen. This is the stronger first move when the buyer needs a very low-surface-tension entry route and the main pressure sits in how the ink or coating meets the film surface during transfer, print formation, or early spread.
That distinction matters because many difficult-film jobs are not only coating problems. They are press-side or converting-side problems where the system has to wet a challenging film face quickly enough to give an honest printed or coated result. Longchang’s current page helps here because 2100 is not only described by chemistry. It is also tied directly to encres d'imprimerie et packaging coatings, with a supported position around difficult-to-wet substrates and a note that small additions will not create stable foam under high-speed dispersion.
2100 usually is the better first route when:
- the target is clearly a film-facing print or packaging-coating application,
- the team wants a difficult-substrate wetting route before broader defect-control changes,
- surface-entry speed matters more than later fluorine-level spray control, or
- the buyer needs a cleaner first screen for difficult films without jumping immediately into a solvent-UV fluorine route.
That makes 2100 the cleaner first move when the real question is not just broad coating wetting, but whether the ink or packaging-coating system can meet the film surface honestly enough to perform.
When FS-D8975BR is the better first move
FS-D8975BR should move ahead when the team already knows the project has gone beyond ordinary wetting. This is the stronger route when the system now needs a more aggressive solvent-based UV surface-control path around anti-cratérisation, prévention de la peau d'orange, nivellement à ondes longues, or tougher final-surface response on difficult film-facing work.
Longchang’s current product page is direct here. FS-D8975BR is supported as a fluorocarbon copolymer solution for solvent-based UV cure, avec bonne compatibilité avec le vernis, excellente capacité anti-cratérisation, adéquation à pulvérisation à grande échelle, and a recommendation block that points to strong glisser together with meaningful dynamic surface-tension control. That is different from simply asking for one more organosilicone wetting trial.
FS-D8975BR usually is the better first route when:
- ordinary wetting additives already improved entry but the surface still is not commercially clean,
- the project sits inside a solvent-based UV window rather than a broad water-based or ink-only screen,
- the defect pattern points toward crater-sensitive or orange-peel-sensitive surface control, ou
- L'acheteur a besoin de plus de force slip and final-surface response than a basic wetting route is giving.
The system boundary must stay visible. FS-D8975BR is not the broad first answer for every film job. It belongs when the work specifically has become a solvent-UV fluorine-surfactant decision.
Comment les acheteurs doivent-ils choisir avant la première série d'échantillons ?
1. Start with the real first failure on the film face
If the coating still cannot enter the difficult film surface cleanly in a broad development window, start with 3071. If the route is clearly packaging-ink or film-print oriented and very low-surface-tension entry matters first, move 2100 ahead. If ordinary wetting already has been screened and the project now needs stronger solvent-UV crater and surface-control logic, move FS-D8975BR forward.
2. Keep broad wetting separate from film-print wetting
A general coating route and a packaging-print route can both mention difficult wetting, but they are not always the same additive decision. Separating those routes early usually makes the first screen cleaner.
3. Keep fluorine escalation separate from ordinary wetting
When the project still has a basic surface-entry failure, start there. Do not jump into a narrower fluorine-surfactant route before proving that the system truly needs it.
4. Respect the watchpoints
3071 may stabilize foam in water-based systems. 2100 belongs earlier when the job is genuinely film-facing and print or packaging oriented. FS-D8975BR belongs in solvent-based UV cure and should not be treated as a general wetting shortcut or a defoamer. Those boundaries are part of the selection logic, not a footnote.
5. Keep the first trial set small and honest
For many low-surface-energy film projects, the cleanest first plan is one 3071 broad wetting route, un 2100 difficult-film wetting routeet un FS-D8975BR fluorine-surfactant escalation route only when the chemistry window really supports it. That usually teaches more than forcing several overlapping products into the same first panel.

FAQ
Which additive should I screen first if a low-surface-energy film still beads or pulls back?
Usually 3071 when the project still needs a broad wetting benchmark across coating systems, or 2100 when the route is more clearly a film-facing print or packaging-coating job and very low-surface-tension entry matters first.
When should 2100 move ahead of 3071?
2100 should move ahead when the application is more directly tied to printing inks or packaging coatings on difficult film surfaces and the team wants a film-facing wetting route before broader defect-control work.
When should FS-D8975BR move ahead of the organosilicone wetting routes?
FS-D8975BR should move ahead when ordinary wetting already has been screened and the remaining problem sits inside a solvent-based UV surface-control lane with crater pressure, orange peel, stronger slip, or tougher flow-control demands.
Is this page the same as the broader wetting-additives page?
No. The broader wetting page helps buyers decide when the problem belongs in the wetting family at all. This page is narrower and helps low-surface-energy film buyers decide which specific route deserves the first trial.
Can one of these three routes solve every low-surface-energy film issue?
No. Their first-screen logic is different enough that buyers should not treat them as interchangeable. The faster path is to define whether the first problem is broad coating wetting, film-print wetting, or a later solvent-UV fluorine-surfactant escalation job.
Besoin d'une liste plus courte ?
If your low-surface-energy film project is stuck between broad wetting failure, film-facing print entry problemset stronger solvent-UV surface-control pressure, 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.
