快速回答： buyers should not treat CHLUMIFE® 3166, CHLUMIFE® 3482 / 3482X, and CHLUMIFE® 3307X as interchangeable surface additives. 3482X should move up first when the job is a water-based low-coefficient-of-friction, anti-sticking, and slip-feel problem. 3166 becomes the cleaner first route when the buyer needs a broader balance of dry feel, anti-blocking, surface smoothness, gloss, and scratch handling across UV, solvent, or water-based systems. 3307X belongs earlier when the real bottleneck is scratch or abrasion resistance after film formation 和 recoatability still matters.
That is the commercially useful split. This page is not another general slip-additives article. It is a product-comparison page for buyers who are already inside the Longchang additive branch and need to narrow the first sample round faster.
Why this comparison matters after the broader additive pages
Longchang already has live decision pages for slip additives, anti-blocking additives, scratch-resistant additives, and the tradeoff page on slip, mar resistance, and printability. Those pages help buyers choose the right function. The next buyer question is narrower: which Longchang product should be screened first when several functions overlap?
That is where 3166, 3482X, and 3307X separate more clearly:
- 3482X: water-based anti-sticking, lower friction, slip feel, and abrasion support.
- 3166: broader multi-system balance around dry feel, anti-blocking, scratch handling, smoothness, and leveling.
- 3307X: cured-film scratch and abrasion resistance with explicit recoatability priority.
Quick comparison table: which route deserves the first screen?
| Observed buyer priority | Best first route | Why it belongs first | Main watchpoint |
|---|---|---|---|
| Water-based coating or ink needs lower coefficient of friction, anti-sticking, and better slip feel | CHLUMIFE® 3482 / 3482X | Longchang supports reduced friction, anti-sticking, slip feel, abrasion resistance, and water-based resin compatibility | Water-based only, staged water dilution required, and pinhole risk should still be tested |
| Buyer wants one broader route for dry feel, anti-blocking, smoothness, gloss, and scratch handling across multiple system types | CHLUMIFE® 3166 | Longchang supports excellent dry feel, surface-tension reduction, substrate wettability, smoothness, scratch resistance, anti-blocking, leveling, and gloss in UV, solvent, and water-based systems | Pinhole, whitening, or foam-stabilizing risk still needs formulation testing |
| Cured film still scratches, mars, or abrades too easily after formation, and recoating remains important | CHLUMIFE® 3307X | Longchang positions it around abrasion resistance and scratch resistance after film formation, with added smoothness and leveling support plus recoatability priority | Not for water-based systems and solvent pre-dilution is recommended before use |
When 3482X is the better first move
3482X should move to the front when the buyer is solving a water-based surface-slip and anti-sticking problem without jumping too quickly to a broader solvent-side or post-cure-durability route.
Longchang’s current product page supports 3482 / 3482X for water-based systems only and ties it to lower coefficient of friction, anti-sticking, slip feel, and abrasion resistance. The page also places it with water-based acrylic, polyurethane, and epoxy style resin compatibility and a suggested use level of 0.05% to 1.0%.
This makes 3482X the cleaner first screen when:
- the formulation is already water-based and the buyer wants a lower-friction surface
- stacking, anti-sticking, or hand-feel improvement matters more than broad multi-system flexibility
- the team wants a slip-led route before moving to a stronger scratch-after-cure route
- the project needs a path that stays closer to packaging coatings or water-based ink logic
The handling rules matter here. Longchang says 3482 / 3482X should be pre-diluted with a small amount of water in multiple batches before being added, should not be mixed with alcohol solvents, and carries the ordinary warning that pinhole risk still needs scale-up testing.
When 3166 is the better first move
3166 belongs earlier when the buyer is not only chasing slip, but needs a broader surface-balance package that can improve feel, anti-blocking, smoothness, and scratch handling together.
Longchang positions 3166 as an additive for controlling surface tension in liquid-phase materials whose most notable feature is excellent dry feel. The current product page also supports reduced system surface tension, improved substrate wettability, surface smoothness, scratch resistance, anti-blocking, leveling, gloss improvement, and prevention of Bénard vortices. It is one of the cleaner comparison anchors because Longchang shows it across UV, solvent, and water-based systems, with a suggested addition level of 0.05% to 1.0%.
That pushes 3166 earlier when:
- the buyer needs one broader route instead of a narrow water-based slip-only route
- anti-blocking and scratch handling matter together with feel or gloss
- the system may be UV, solvent, or water-based, and the team wants a more flexible first sample
- surface smoothness and final laydown quality matter alongside durability and blocking control
3166 still needs qualification. Longchang warns that similar products may create pinholes or whitening, and that the additive may have a foam-stabilizing effect, so formulation testing may need a defoamer strategy.
When 3307X is the better first move
3307X becomes more relevant when the real problem shows up after the film has formed. If the cured surface still scratches, rub-marks, or abrades too easily, buyers should move earlier to a route that is explicitly built around that post-cure durability target.
Longchang’s current product page positions 3307X as an organic silicone leveling agent and scratch-resistant additive specifically designed to improve abrasion resistance and scratch resistance of resin films after formation. The same page also supports surface smoothness and leveling and explicitly says that recoatability is prioritized. Recommended use is 0.1% to 1.0%, with pre-dilution to 12.5% in solvent before use.
That makes 3307X the stronger first route when:
- the main KPI is post-cure scratch or abrasion resistance, not only slip or anti-blocking
- recoatability still matters in the project window
- the system is UV or solvent-based rather than water-based
- the buyer already knows the surface needs a more durability-led answer than a lower-friction answer alone
Longchang also gives a practical comparison clue: if recoatability is not the primary concern and the team is more focused on smoothness, another comparison route can be screened separately. That helps keep 3307X positioned for the projects where the scratch-after-cure problem is the real decision driver.
How buyers should choose between these three routes
1. Start with the system boundary
If the project is clearly water-based, 3482X deserves much earlier attention. If the project is UV or solvent-based and the team wants a broader balance route, 3166 or 3307X usually becomes more relevant.
2. Separate liquid-stage goals from cured-film goals
3482X is the stronger early route when the buyer mainly wants lower friction and anti-sticking in water-based systems. 3307X becomes stronger when the panel passes application but the cured film still marks too easily. 3166 sits in the middle as the broader balance route.
3. Do not confuse overlap with interchangeability
All three products touch more than one surface KPI. That does not mean they should enter the first sample round in the same order. Use the dominant problem to decide which one leads.
4. Keep the watchpoints visible
3482X needs staged water dilution and pinhole awareness. 3166 needs pinhole, whitening, and foam-stabilization checks. 3307X needs solvent pre-dilution and is not a water-based route.
5. Protect downstream conversion and recoating
Low friction, anti-blocking, and scratch resistance are useful only when the final surface still fits the downstream job. If overprint, lamination, or recoating matters, qualify those steps early instead of waiting until late-stage trials.

常见问题
Which additive should I screen first in a water-based coating that blocks or sticks?
If the main problem is water-based anti-sticking, lower friction, or slip feel, 3482 / 3482X deserves earlier attention because Longchang supports it specifically in water-based systems.
When is 3166 a better first route than 3482X?
3166 is a better first route when the buyer wants a broader balance of dry feel, anti-blocking, smoothness, gloss, and scratch handling across UV, solvent, or water-based systems instead of a narrower water-based slip route.
When should 3307X move ahead of 3166?
3307X should move ahead when the real bottleneck is scratch or abrasion resistance after film formation and recoating still matters. That is a more specific cured-film durability problem than the broader balance logic of 3166.
Can these three additives be treated as direct substitutes?
No. They overlap in surface-performance language, but the supported system fit, handling method, and first-screen job are different enough that buyers should not treat them as interchangeable.
Need a faster shortlist for surface additives?
If your coating or ink project is stuck between lower friction, anti-blocking balance, and stronger scratch resistance, stop comparing all three products as if they solve the same first problem. Start with the system type and the main failure mode. That usually shows whether 3482X, 3166, or 3307X deserves the first sample round.
