Quick answer: buyers comparing CHLUMILE® 3032, CHLUMILE® 3233, and CHLUMILE® 3432 usually get a cleaner shortlist when they separate three different first-screen jobs instead of treating every leveling additive as the same silicone tool. 3032 should move first when the project is an oil-based pigment, ink, or leather-finishing route that needs reactive durable surface control. 3233 belongs earlier when the buyer needs excellent compatibility with hydrocarbons or their emulsion systems and values feel improvement plus some defoaming support. 3432 deserves earlier review when the real problem is print-face smoothness, wetting, anti-cratering, and low-foam leveling in printing inks, varnishes, or UV-curable coatings.
That is the commercially useful split. This page is not another broad leveling article. It is a tighter CHLUMICRYL® comparison page for buyers who already know the job belongs in the surface-leveling lane and need a faster first sample round.
Why this comparison is a cleaner next step than another broad ink or coating page
Longchang already has live pages for leveling additives for coatings and inks, offset ink additives, gravure ink additives, and UV coating flow and leveling. Those pages help buyers decide which function branch they are in. The next buyer question is narrower: which Longchang leveling product should be screened first when the project is stuck between reactive oil-based leveling, hydrocarbon-heavy compatibility, and printing-ink surface smoothness?
That makes a product-vs-product shortlist cleaner than another broad application page. The intent here is not “what is a leveling additive?” It is “which supported Longchang route deserves the first lab trial?”
What these three routes share, and where they split
All three product pages place the additives in broad coating-system windows, but the practical selection logic separates quickly.
- CHLUMILE® 3032 is positioned as a reactive silicone leveling agent for pigments and inks and oil-based coatings. Longchang says it can improve surface smoothness, scratch resistance, anti-blocking, and release properties, and that its hydroxyl functional groups can crosslink to the surface to achieve more durable properties.
- CHLUMILE® 3233 is positioned around surface-tension control with excellent compatibility with hydrocarbons and their emulsion systems. Longchang also says it can improve feel, resist substrate oil stains, and defoam, while showing strong mineral-oil affinity in daily chemical systems.
- CHLUMILE® 3432 is positioned as a high-efficiency leveling route with excellent smoothness, low foaming stability, abrasion and scratch resistance, increased substrate wetting, and anti-cratering, with explicit application fit for printing inks, overprint varnishes, wood coatings, and UV coatings.
That is enough separation to justify a distinct buyer page.
Quick comparison table: which route deserves the first screen?
| Observed buyer priority | Best first route | Why it belongs first | Main watchpoint |
|---|---|---|---|
| Oil-based pigment, ink, or leather-finishing route needs durable surface leveling with anti-blocking and release support | CHLUMILE® 3032 | Longchang explicitly frames it for pigment and ink leveling with reactive hydroxyl functionality for durable surface properties | Avoid mixing with other additives and keep the route tied to suitable solvent-side systems |
| Formulation needs strong hydrocarbon compatibility, broader dilution flexibility, feel improvement, and some defoaming support | CHLUMILE® 3233 | Longchang positions it around hydrocarbons and emulsion compatibility, oil-stain resistance, feel improvement, and defoaming support | It cannot completely replace an oil-based defoamer when rapid defoaming is the real bottleneck |
| Printing ink, varnish, or UV-curable surface needs smooth laydown, wetting, and anti-cratering with lower foam instability | CHLUMILE® 3432 | Longchang explicitly positions it for smoothness, high efficiency, wetting, anti-cratering, and printing-ink or varnish use | Industrial-production testing is still required before scale-up |
When CHLUMILE® 3032 is the better first move
3032 should move earlier when the buyer is solving an oil-based pigment or ink leveling problem and wants a route that is not only surface-slick but also tied to durable surface fixation. Longchang calls it a reactive silicone leveling agent for pigments and inks and an oil-based coating leveling agent. The product introduction also says it improves surface smoothness, scratch resistance, anti-blocking, and release properties, while its hydroxyl functional groups can crosslink to the surface through reactive groups.
That makes 3032 the cleaner first route when:
- the project is already solvent-side or oil-based rather than a broad waterborne screening exercise
- the team wants a reactive durability story instead of a compatibility-first route
- anti-blocking and release behavior matter alongside leveling
- pigment, ink, or leather-finishing work is part of the brief
Longchang recommends 0.01% to 1% dosage, allows addition at any production stage, and says it can be diluted with alkanes and aromatics in any ratio. The main watchpoint is that the current product page says to avoid mixing with other additives, so buyers should keep the trial design disciplined.
When CHLUMILE® 3233 is the better first move
3233 belongs earlier when the real decision is about compatibility inside hydrocarbon-rich systems, especially if the project also wants some help on feel, oil-stain resistance, and defoaming support. Longchang describes 3233 as an additive used to control the surface tension of liquid-phase materials with excellent compatibility with hydrocarbons and their emulsion systems. The same page says it can improve feel, resist substrate oil stains, and defoam.
That makes 3233 the better first route when:
- the formula carries a strong hydrocarbon or mineral-oil compatibility constraint
- the buyer does not want a narrower pigment-and-ink reactive route first
- surface feel matters alongside leveling
- some foam cleanup is helpful, but the job is not primarily a heavy-foam emergency
Longchang recommends 0.1% to 1.0% dosage and allows dilution with water, alcohols, alkanes, and aromatics. The product page also gives an important boundary: 3233 cannot completely replace oil-based defoamers, and for fast defoaming Longchang recommends adding a diluted solution of BD-FT-50. That is exactly why 3233 is a compatibility-led leveling route, not a substitute for a true defoamer-first correction.
When CHLUMILE® 3432 is the better first move
3432 deserves earlier attention when the buyer is not mainly chasing hydrocarbon compatibility or reactive crosslinking, but instead needs a cleaner route for surface smoothness, wetting, and anti-cratering in printing inks, overprint varnishes, wood coatings, or UV coatings. Longchang’s current product page is direct here: 3432 offers excellent smoothness, high efficiency, low foaming stability, abrasion and scratch resistance, increased substrate wetting, and anti-cratering properties.
That makes 3432 the cleaner first route when:
- the real pain point is print-face appearance or varnish laydown
- substrate wetting and anti-cratering matter as much as leveling
- the team wants a route explicitly tied to printing inks and overprint varnishes
- the buyer wants a simpler print-surface benchmark before moving to more reactive specialty routes
Longchang recommends 0.05% to 1% dosage, allows dilution with water, alcohols, alkanes, and aromatics, and notes that testing before industrial production is still required. In practice, 3432 is the strongest first screen when the visible finished-surface quality is the main decision driver.
How buyers should choose before asking for samples
1. Start with the real formulation boundary
If the project is clearly an oil-based pigment or ink route and reactive durability matters, 3032 deserves earlier attention. If hydrocarbon compatibility is the main risk, 3233 should move up. If the project is a printing-ink or varnish appearance problem, 3432 is usually the cleaner first benchmark.
2. Separate reactive durability from compatibility-first screening
3032 is the reactive durability-led route. 3233 is the compatibility-led route. 3432 is the print-surface appearance and wetting-led route. That separation usually reduces wasted first-round trials.
3. Keep foam expectations realistic
3233 can support defoaming, but Longchang explicitly says it cannot fully replace an oil-based defoamer for rapid foam collapse. 3432 is framed around lower foam stability, while 3032 is not the first answer for a foam-heavy correction job.
4. Use the real watchpoint, not only the headline benefit
3032 needs disciplined additive pairing. 3233 should not be misused as a full defoamer replacement. 3432 still requires production-stage testing. Those are practical reasons one route will beat another in a real buying decision.
5. Keep the first sample round short
For many buyers, the best first round is one reactive oil-based route, one hydrocarbon-compatible route, and one printing-surface smoothness route. That usually teaches more than loading the first panel with too many overlapping leveling agents.

FAQ
Which additive should I screen first for oil-based pigment and ink leveling?
Usually CHLUMILE® 3032, because Longchang explicitly positions it for pigment and ink leveling in oil-based systems and ties it to reactive durable surface control.
When is 3233 a better first route than 3032?
3233 is a better first route when hydrocarbon compatibility, emulsion-system fit, feel improvement, and some defoaming support matter more than a reactive pigment-and-ink story.
When should 3432 move ahead of the other two?
3432 should move ahead when the real issue is print-face smoothness, wetting, anti-cratering, and low-foam leveling in printing inks, varnishes, or UV-curable surfaces.
Can 3233 replace a true oil-based defoamer?
No. Longchang explicitly says it cannot completely replace oil-based defoamers for rapid defoaming, so buyers should keep that boundary clear during selection.
Need a tighter leveling shortlist for coatings and inks?
If your team is stuck between a reactive oil-based route, a hydrocarbon-compatible route, and a printing-surface smoothness route, define the real first-screen job before requesting samples. That usually shows much faster whether CHLUMILE® 3032, 3233, or 3432 deserves the first trial.
