3032 vs 3233 vs 3432 should be decided by formulation evidence, not by overlapping leveling language. CHLUMILE® 3032 is the qualitative hydroxyl-reactive, oil/pigment route but publishes no hydroxyl value or active content. CHLUMILE® 3233 is the 100%-active hydrocarbon-compatible route and cannot replace a true oil-based defoamer. CHLUMILE® 3432 is the 100%-active printing/UV route, but its waterborne fit is ambiguous.
The 3432 introduction says solvent-based and UV-curable coatings while its system table also marks water-based. Confirm the current TDS before any aqueous trial.
3032/3233/3432 decision map
| Formulation evidence | First route | Mandatory gate |
|---|---|---|
| Oil-based pigment/ink needs a potentially reactive leveling route | 3032 after reaction data | Active content, OH/equivalent and cure impact |
| Hydrocarbon or mineral-oil-rich system needs compatibility/feel | 3233 | Do not interpret partial defoaming as full foam control |
| Solvent or UV printing ink needs leveling, low foam stabilization and anticrater support | 3432 | Verify waterborne status separately |
| Defect follows contamination, under-cure or trapped air | Correct cause first | No leveling-additive approval |
| Termék | Published data | First-screen role | Boundary |
|---|---|---|---|
| 3032 | Polyether-modified polysiloxane; 0.01–1%; water/UV/solvent checkmarks | Oil-based pigment/ink leveling with qualitative reactive OH claim | No public active %, OH value or equivalent; avoid mixing |
| 3233 | Modified polysiloxane; 100% active; 0.1–1%; water/UV/solvent | Hydrocarbon compatibility, feel, oil-stain resistance and some defoaming | Page says it cannot completely replace oil-based defoamers |
| 3432 | Polyether-modified polysiloxane; 100% active; 0.05–1% | Solvent/UV coatings, printing inks, leveling and anticrater support | Waterborne checkmark conflicts with solvent/UV application prose |
Define the failure and system
Record resin, pigment, water/solvent/mineral-oil phase, solids, surface tension, viscosity, cure and substrate. Map when the defect appears. Immediate retraction may be contamination or wetting; late haze or softness may be compatibility or cure; bubbles require an air diagnosis.
Hold film weight, application and cure. Leveling cannot be ranked from panels with different sag, solvent loss or cure state.
Use 3032 only after quantitative reaction review
3032 claims hydroxyl functionality and durable crosslinking effects, with a 0.01–1% total range. The page gives no hydroxyl value, equivalent weight or active content. Do not calculate crosslinker demand or claim permanent fixation from the website alone.
Obtain the current TDS/CoA, identify the actual reactive partner and include the additive in NCO/OH or other stoichiometry when applicable. Measure pot life, cure, hardness and chemical resistance.
Use 3233 for hydrocarbon compatibility
3233 is 100% active and positioned for hydrocarbons, their emulsions and mineral-oil-rich products. It also supports feel, leveling, oil-stain resistance and some defoaming. That makes it a compatibility-led screen, not a universal ink defoamer.
The page explicitly says it cannot completely replace oil-based defoamers. If foam is the main failure, run a dedicated defoamer trial with standardized mixing and circulation.
Use 3432 after resolving waterborne ambiguity
3432 supports printing inks, overprint varnishes, solvent and UV coatings, low foam stabilization, scratch/abrasion, wetting and anticrater behavior. Its table also marks waterborne, creating a conflict with the prose.
For solvent/UV systems, test within 0.05–1%. For waterborne work, request written system confirmation and an incorporation method before sampling. Do not infer water stability from a checkmark alone.
Run a controlled surface trial
- Prepare a blank plus one focused product ladder.
- Report supplied-product and active addition where known.
- Hold resin, solvent, pigment, viscosity, film weight and cure.
- Measure leveling, craters, gloss/haze, color, foam and drying.
- Repeat after liquid and finished-film storage.
Measure print and coating durability separately
ASTM D5264 provides a rub comparison for printed materials. ASTM D4060 evaluates abrasion resistance of organic coatings on flat rigid panels. Choose the method that fits the substrate and end use.
Pair these with adhesion, cure, blocking, scratch, friction, gloss and recoat. A smoother surface that loses ink adhesion or changes cure is not a passing result.
Use defect timing to interpret results
Observe the wet film immediately after application, during flash, at tack-free time and after full cure. Immediate craters that repeat around contamination points are different from late pinholes caused by air release. Haze that grows during cure may indicate compatibility or phase separation rather than poor leveling.
Photograph a fixed area under the same lighting and count defects by type. Record wet and dry film thickness beside gloss and leveling. If a candidate merely increases sag or changes solvent release, an apparently smoother panel is not evidence of a better surface-additive balance.
Confirm storage and recoat before scale-up
Age both the liquid formulation and coated panels under customer-approved conditions. Recheck viscosity, separation, foam, craters, gloss, adhesion, rub or abrasion and recoat. For 3032, also repeat cure-sensitive properties; for 3432 waterborne trials, monitor clarity and separation because the public system description is unresolved.
Common comparison errors
Calling 3032 quantitatively reactive
No public OH value or equivalent is supplied.
Using 3233 as the only defoamer
The page explicitly limits that expectation.
Assuming 3432 is proven waterborne

Request a formulation-specific shortlist
Send resin/system, pigments, solvent/water/mineral oil, crosslinker, cure, current additives, defect timing, foam data and leveling, gloss, rub/abrasion, adhesion and recoat requirements. Ask Longchang Chemical to resolve the 3032 reaction data and 3432 waterborne boundary.
