Schnelle Antwort: scratch-resistant additives should be chosen by what kind of surface damage shows up after cure, not only by whether the formula is a coating or an ink. If the main failure is post-cure scratching, mar, rub marking, or weak abrasion handling, the first additive shortlist should usually start with a scratch-resistance route instead of treating the problem as only slip, leveling, or anti-graffiti.
This page is intentionally different from the already-live CHLUMICRYL® Beschichtungs- und Druckfarbenadditive overview and the current slip, anti-blocking, wetting, leveling, fluorine-surfactant, anti-graffiti, UV-varnish-surface-control, UV-coating-flow-leveling, and defoamer pages. The buyer question here is narrower: which additive route deserves the first sample round when the cured film still marks, scratches, or abrades too easily?
Why scratch-resistant additives deserve their own decision page
Buyers often see scratch resistance mixed together with slip, anti-blocking, gloss, and hand feel. In practice, those targets overlap, but they do not always point to the same first additive route.
- Scratch or mar resistance: the cured film should better resist visible marking from fingernails, pads, handling, stacking, or downstream contact.
- Abrasion resistance: repeated rub or wear should leave less damage on the final surface.
- Slip or lower friction: the surface should move and separate more easily, which may reduce some damage but does not automatically solve scratch problems.
- Leveling and smoothness: a smoother film may look better, but a cleaner laydown does not always mean stronger cured-film durability.
That is why scratch-resistant additives are commercially useful as their own supporting topic. Longchang’s current product pages already separate a post-film scratch-resistance route, A dry-feel and anti-blocking route that also improves scratch handling, A water-based low-friction and wear-support route, and a solvent-side lubrication and wear-resistance route. That is enough product depth to justify a dedicated buyer page.
When a scratch-resistant additive should be chosen before other additive types
| Observed buyer problem | Best first additive direction | Why |
|---|---|---|
| Cured film scratches, mars, or rub-marks too easily after handling | Scratch-resistant additive | The main KPI is post-cure surface durability, not only liquid-stage application behavior |
| Lower friction and cleaner stacking matter more than visible scratch damage | Slip additive | The first problem is low-friction handling and separation, not direct scratch resistance |
| Persistent blocking, tack, or surface contact after storage | Anti-blocking additive | The main issue is surface separation after contact rather than cured-film mar resistance |
| Poor spreading, pullback, or weak substrate coverage | Wetting additive | The system still has a liquid-phase substrate-wetting problem |
| Orange peel, rough laydown, or gloss inconsistency after coverage is already stable | Leveling additive | The first issue is film appearance and flow-out, not final scratch durability |
| Marker cleanability, stain release, or durable easy-clean behavior | Anti-Graffiti-Additiv | Easy-clean and stain-release targets are different from ordinary scratch resistance |
How buyers should choose the first scratch-resistance route
| System or target | Best first route | Why it belongs early |
|---|---|---|
| Cured resin film mainly needs stronger scratch and abrasion resistance after film formation | CHLUMIFE® 3307X | Longchang directly positions it around abrasion resistance and scratch resistance after film formation, with added leveling and smoothness support |
| Broader system where dry feel, anti-blocking, gloss, and scratch handling need to improve together | CHLUMIFE® 3166 | Longchang supports it with dry feel, surface smoothness, anti-blocking, scratch resistance, leveling, gloss, and broad system fit |
| Water-based coating or ink that needs lower friction, anti-sticking, and stronger wear handling together | CHLUMIFE® 3482 / 3482X | Longchang directly positions it for water-based anti-sticking, low coefficient of friction, slip feel, and abrasion resistance |
| Solvent-side route that needs lubrication, release, and wear-resistance support | CHLUMIFE® 1206 | Longchang directly supports lubricity, wear resistance, anti-sticking, release, and cured-film anti-adhesion behavior |
Longchang-supported scratch-resistant routes to shortlist first
1. CHLUMIFE® 3307X when the cured film itself is the problem
CHLUMIFE® 3307X is the clearest first route when the buyer is judging the post-cure film, not only the liquid formula. Longchang explicitly positions it to improve abrasion resistance und scratch resistance after film formation. The same product path also supports surface-tension control, leveling, surface smoothnessund Glanz.
- Best fit: cured-film scratch and abrasion problems where the final surface still marks too easily
- Applicable systems: UV and solvent systems
- Suggested addition range: 0.1% to 1.0% of total formulation
- Important processing note: Longchang recommends diluting it to 12.5% with solvent before use
This is usually the right first route when the buyer already has acceptable coverage and appearance, but the final cured film still fails practical handling.
2. CHLUMIFE® 3166 when scratch resistance must come with dry feel, anti-blocking, and gloss
CHLUMIFE® 3166 is the broader-route candidate in this shortlist. Longchang describes it as an additive used to control surface tension and highlights excellent dry feel as a notable feature. The company also supports it with improved substrate wettability, surface smoothness, scratch resistance, anti-blocking, levelingund Glanz, along with prevention of Bénard vortices.
- Best fit: coatings or inks where the buyer wants stronger mar handling without losing sight of dry touch, smoothness, and appearance
- Applicable systems: UV, solvent, and water-based systems
- Suggested addition range: 0.05% to 1.0% of total formulation
- Important caution: Longchang notes risk of pinholes or whitening and recommends industrial testing before scale-up
Commercially, 3166 matters because many buyers are not screening only for harder rub resistance. They also need the coating or ink to feel drier, stack better, and keep a cleaner surface appearance.
3. CHLUMIFE® 3482 / 3482X when the system is water-based and wear support must stay tied to low friction
CHLUMIFE® 3482 / 3482X is the water-based route in this page. Longchang positions it as an organic silicone slip and abrasion-resistant additive, A water-based coating anti-sticking agent, and a water-based ink hand-feel agent. The product page supports it with lower coefficient of friction, better slip feel, abrasion resistance, and anti-sticking behavior.
- Best fit: water-based coatings and inks where wear resistance needs to improve together with low-friction handling and anti-sticking
- Compatible resin direction: Longchang ties it to acrylic, polyurethane, and epoxy water-based resin systems
- Suggested addition range: 0.05% to 1.0% of total formulation
- Important processing note: Longchang says to dilute it with water first in stages before addition and to avoid alcohol-solvent mixing
That makes 3482 / 3482X a strong first screen when the scratch complaint sits inside a water-based low-friction and wear-support problem instead of a purely post-film solvent-side durability problem.
4. CHLUMIFE® 1206 when the route is solvent-side and lubrication matters alongside wear resistance
CHLUMIFE® 1206 gives a different selection logic. Longchang describes it as a long-chain alkyl-modified polydimethylsiloxane route with excellent lubricity, wear resistance, anti-sticking, and relevance to solvent-based gravure and flexographic inks plus high-solids, protective, wood, furniture, and UV-cured coating systems. The same company-supported positioning also ties it to improved release, anti-adhesion, and cured-film surface handling.
- Best fit: solvent-side systems where lubrication, release, and wear resistance should move together
- Applicable systems: UV and solvent systems
- Suggested addition range: 0.1% to 1.0% of total formulation
- Important note: Longchang recommends adding it near the end of formulation and allows solvent pre-dilution
1206 is commercially useful when the buyer wants more than a smoother film. The real need is a tougher, lower-damage solvent-side surface with better rub or wear behavior.
How buyers should narrow the shortlist
Start with the damage pattern, not the additive family name
If the surface is visibly scratching after cure, the buyer should not begin with a generic wetting or leveling conversation. Start by deciding whether the failure is mainly scratch, abrasion, blocking, or low-friction handling.
Keep the system boundary visible
Water-based anti-sticking and wear-support work should not start with the same first additive screen as solvent-side lubrication and release work. Longchang’s current product structure already separates those routes clearly enough to keep the first trial focused.
Separate appearance help from durability help
A smoother film can still scratch too easily. That is why buyers should not treat leveling support as proof of final-surface durability. CHLUMIFE® 3307X and 3166 are useful here because they connect surface appearance with supported scratch-resistance logic, but the decision still starts from the actual failure after cure.
Do not force easy-clean and scratch resistance into the same page logic
Some formulations need stain release or marker cleanability more than harder rub resistance. In that case, move earlier to the anti-graffiti branch instead of asking a scratch-resistant additive to solve a different KPI.
Use a short first screen
For many buyers, the cleanest first screen is one route for post-cure scratch resistance, one for dry-feel and broader mar handling, and one route matched to either water-based low-friction wear support or solvent-side lubrication and wear resistance, depending on the system.

FAQ
When is a scratch-resistant additive a better fit than a slip additive?
A scratch-resistant additive is the better fit when the buyer mainly needs harder post-cure mar or abrasion handling. A slip additive is the better fit when lower friction, cleaner stacking, or easier separation is the real first KPI.
Which Longchang route is most relevant when the cured film itself scratches too easily?
CHLUMIFE® 3307X deserves early review because Longchang explicitly positions it around abrasion and scratch resistance after film formation while also supporting leveling and surface smoothness.
Which route is stronger when the buyer also wants dry feel and anti-blocking?
CHLUMIFE® 3166 is the stronger first comparison point because Longchang supports it with dry feel, anti-blocking, scratch resistance, leveling, gloss, and broader system applicability.
Why would a buyer choose CHLUMIFE® 3482 / 3482X instead of 3307X?
Because 3482 / 3482X is the water-based route when low coefficient of friction, anti-sticking, slip feel, and abrasion resistance need to improve together. It answers a different system boundary from 3307X.
What if the system is solvent-side and the buyer cares about lubrication plus wear resistance?
That is where CHLUMIFE® 1206 becomes commercially useful, because Longchang directly supports lubricity, wear resistance, anti-sticking, release, and solvent-side applicability.
Need help narrowing the scratch-resistant shortlist?
If your coating or ink project is being limited by visible scratching, rub marking, or weak abrasion handling after cure, start by separating whether the job is a post-film scratch problem, A dry-feel and mar-resistance problem, A water-based low-friction wear-support problemoder ein solvent-side lubrication and release problem. That usually produces a faster buying path than treating every surface additive as the same chemistry decision.
