Gyors válasz: fluorine surfactants are usually the right shortlist when a coating or ink needs more aggressive surface control than a standard wetting or leveling additive is giving you. In practical buying terms, they belong early when the system shows persistent craters, orange peel, difficult substrate response, slip demands, or a need to manage shrinkage and recoat behavior in solvent-based UV systems.
That makes this page narrower than the broader CHLUMICRYL® bevonat- és tintaadalékok overview. It is for buyers who already know the formulation problem sits at the surface, and now need to decide when a fluorine-surfactant route is a better fit than a leveling additive, wetting additive, or anti-graffiti additive.
What fluorine surfactants solve in coatings and inks
Across the coatings and inks market, fluorine surfactants are commonly used when formulators need strong surface-tension reduction and tighter control over wetting, leveling, crater resistance, and final-surface behavior. For Longchang’s current CHLUMICRYL® branch, that general market framing aligns with a fluorocarbon-copolymer product set built for Oldószer alapú UV kikeményítés and positioned around varnish compatibility, anti-cratering, long-wave leveling, slip, and related surface-control work.
Typical buyer-side warning signs include:
- Persistent craters or shrinkage: the film still defects after ordinary additive changes.
- Orange peel or weak long-wave leveling: the surface cures, but still does not settle cleanly.
- Difficult wetting or surface-tension control: the coating or ink needs stronger spreading and surface response control.
- Slip or special final-surface behavior: the system needs more than simple flow improvement.
- Silicone-additive restrictions: the project needs a surface-control route for systems where silicone additives cannot be used.
If one of those is the real bottleneck, fluorine surfactants deserve a focused screen instead of being treated as a last-minute additive swap.
When to choose fluorine surfactants before other additive types
| Observed problem | Best first additive direction | Why |
|---|---|---|
| Persistent craters, anti-shrinkage pressure, or stronger surface-tension control needs | Fluoros felületaktív anyag | The system needs a more specialized surface-control route |
| Basic spreading problems on plastic, film, or metal | Wetting additive | Start with substrate coverage if the problem is still basic wetting |
| Orange peel or gloss inconsistency after acceptable wetting | Leveling additive | Standard flow and appearance control may be enough before moving to a narrower fluorine route |
| Pigment instability, flooding, or color drift | Diszpergálószer | The root problem is pigment management, not surface control |
| Final cleanability or graffiti-resistance requirements | Graffiti-ellenes adalékanyag | The decision is driven more by end-use maintenance than by coating application defects alone |
CHLUMICRYL® fluorine-surfactant routes to review first
The current Longchang fluorine-surfactant branch already gives a practical shortlist of fluorocarbon-copolymer solutions for solvent-based UV cure. The strongest first review set is usually CHLUMICRYL® FS-D9013R, CHLUMICRYL® FS-D8975BR, CHLUMICRYL® FS-D8950BRés CHLUMICRYL® FS-D8980.
CHLUMICRYL® FS-D9013R
- What Longchang supports: fluorocarbon copolymer solution for solvent-based UV cure
- Key supported surface-control points: good long-wave leveling, anti-cratering, fast leveling speed, high-temperature resistance, and recoating support
- Important selection note: Longchang explicitly positions it for systems where silicone additives cannot be used, while also noting that it is not applicable in UV vacuum electroplating primer because it will affect recoating
- Suggested addition range: 0.1% to 1.0% of total formulation
CHLUMICRYL® FS-D8975BR
- What Longchang supports: fluorocarbon copolymer solution for solvent-based UV cure
- Key supported surface-control points: good compatibility in varnish, good long-wave leveling, excellent anti-cratering ability, suitability for large-area spraying, and no foam inhibition
- Why it belongs early: Longchang also gives it strong slip and surface-tension guidance in the product recommendation block, which makes it a practical route when the buyer needs both appearance control and final-surface response
- Suggested addition range: 0.05% to 0.8% of total formulation
CHLUMICRYL® FS-D8950BR
- What Longchang supports: fluorocarbon copolymer solution for solvent-based UV cure
- Key supported surface-control points: good compatibility in varnish, long-wave leveling, anti-cratering, suitability for large-area spraying, and no foam inhibition
- Why it belongs early: it gives another practical fluorine route for buyers who need to compare active-content level and application-window fit inside the same CHLUMICRYL® surface-control family
- Suggested addition range: 0.1% to 1.0% of total formulation
CHLUMICRYL® FS-D8980
- What Longchang supports: fluorocarbon copolymer solution for solvent-based UV cure
- Key supported surface-control points: good compatibility in varnish, good long-wave leveling, anti-orange-peel support, suitability for large-area spraying, and no foam inhibition
- Why it belongs early: Longchang’s recommendation block again points to strong slip and useful dynamic and static surface-tension control, which is commercially relevant when buyers need a more specialized surface-behavior screen
- Suggested addition range: 0.05% to 0.8% of total formulation
How buyers should screen fluorine surfactants
1. Confirm that standard wetting or leveling changes are not enough
Fluorine surfactants are strongest when the issue is not just ordinary spreading or film appearance, but a more stubborn surface defect or stronger surface-response target.
2. Separate silicone-free needs from general surface tuning
If the formulation cannot use silicone additives, FS-D9013R deserves early attention because Longchang explicitly positions it for that case.
3. Screen by defect type, not by additive family name alone
A crater problem, an orange-peel problem, and a slip-demand problem can all land in the fluorine branch, but buyers should still define which one matters most before comparing products.
4. Keep recoating and downstream process fit visible
Longchang’s own note on FS-D9013R shows why this matters. A product can be valuable for common UV primer anti-cratering work while still being the wrong fit for UV vacuum electroplating primer.
5. Start with a short first shortlist
For the current CHLUMICRYL® branch, the cleanest first comparison is usually FS-D9013R, FS-D8975BR, FS-D8950BR, and FS-D8980 rather than a mixed test across unrelated additive families.

GYIK
What is the main reason to use a fluorine surfactant in coatings or inks?
The main reason is to solve a stronger surface-control problem, such as persistent craters, difficult wetting, orange peel, shrinkage, slip, or other final-surface behavior that ordinary additive choices are not handling well enough.
Should I start with a fluorine surfactant or a wetting additive?
Start with a wetting additive when the problem is still basic substrate coverage. Move to a fluorine-surfactant route when the issue is more specialized surface control or when standard wetting adjustments are not enough.
Why is FS-D9013R an important comparison point?
Because Longchang explicitly positions it for silicone-free systems, anti-cratering, fast leveling, and recoating support in common UV primer work, which makes it commercially distinct inside the branch.
Can the same fluorine-surfactant route work for every UV coating or ink?
No. Buyers should still screen by formulation type, defect profile, recoating requirement, and process constraints. Longchang’s note that FS-D9013R should not be used in UV vacuum electroplating primer is a good reminder that surface-control fit is application-specific.
Need help narrowing the fluorine-surfactant shortlist?
If your UV coating or ink project is still fighting craters, orange peel, shrinkage, difficult wetting, or special final-surface behavior after ordinary additive changes, start with the specific defect and compare the most relevant CHLUMICRYL® fluorine-surfactant routes first. That usually creates a cleaner buying path than treating fluorine chemistry as a generic last-step fix.
