3032 vs 3432 vs 3501 is a comparison of three different evidence levels, not three interchangeable surface additives. CHLUMILE® 3032 is the oil/pigment leveling route with a qualitative hydroxyl-reactive claim but no public active content or hydroxyl value. CHLUMILE® 3432 is the 100%-active, dosed printing and coating route. CHLUMIAG® 3501 lists printing, overprint-varnish and release applications but publishes no dosage.
Choose by system, first failed endpoint and the data needed for approval. Smoothness, rub, blocking, release and cure are separate results.
3032/3432/3501 decision map
| Formulation evidence | First route | Approval gate |
|---|---|---|
| Oil-based pigment or ink needs leveling and a potentially reactive surface effect | 3032 after reaction-data review | Active content, OH value/equivalent and cure balance |
| Solvent or UV print face needs leveling, wetting, anticrater support and controlled wear | 3432 | Resolve waterborne ambiguity; check rub, adhesion and recoat |
| Printing or release project specifically requires 3501 | Evidence request before a dose ladder | Current dosage and quantified endpoint |
| Defect is trapped air, contamination or under-cure | Correct the mechanism | No surface-additive ranking |
| Termék | Published data | Documented role | Critical boundary |
|---|---|---|---|
| 3032 | Polyether-modified polysiloxane; 0.01–1%; system table marks water/UV/solvent | Oil-based coatings, pigments and inks; qualitative hydroxyl-reactive route | No public active %, OH value or equivalent; dilution guidance names alkanes/aromatics |
| 3432 | 100% active; 0.05–1%; water/alcohol/alkane/aromatic dilution | Printing inks, overprint varnishes, solvent and UV coatings | Water checkmark conflicts with the solvent/UV application prose |
| 3501 | Multi-component modified polysiloxane; 100% active; all three system checkmarks | Printing, inkjet, screen ink, overprint varnish and anti-sticking/release categories | No public recommended dosage or quantified rub, block or release result |
Define the first failed endpoint
Record resin, water/solvent/UV phase, pigments, substrate, film weight, cure and downstream contact. Observe the film immediately, during flash and after full cure. Immediate retraction, circulating foam, late haze, blocking and poor rub resistance require different experiments.
Lock application, solvent loss and cure before judging leveling. A panel that appears smoother because it sagged or cured less is not an improvement.
Use 3032 only with reaction evidence
3032 is published at 0.01–1% and is positioned for oil-based pigment and ink leveling. Its hydroxyl-functional claim suggests a possible reaction route, but the page supplies neither active content nor a hydroxyl value/equivalent. Do not calculate crosslinker demand or claim permanent fixation from that page.
Request the current TDS and CoA, identify the reactive partner and include the additive in stoichiometry when applicable. Check pot life, cure, hardness, chemical resistance, adhesion and recoat.
Use 3432 for a dosed print-surface screen
3432 supplies a 0.05–1% total-formulation range, 100% active content and printing/overprint-varnish applications. It is the most directly calculable route for solvent or UV work in this comparison. Start low and test leveling, craters, gloss, color, rub, blocking and adhesion.
Its table marks waterborne use and water dilution, while its product introduction names solvent and UV coatings. Treat aqueous use as unresolved until current written guidance confirms resin compatibility, incorporation and storage stability.
Keep 3501 behind an evidence gate
3501 names relevant printing and release categories, but no public dosage is available. The page also provides no defined release force, rub cycles, blocking load or heat/pressure condition. Those omissions prevent a controlled first ladder and a meaningful claim comparison.
If 3501 is specifically requested, obtain a supplier-supported dose and endpoint protocol first. Compare it with the blank and the current production reference rather than assuming that an application label proves performance.
Control incorporation and storage
Record addition stage, predilution solvent, ratio, batch temperature and mixing energy. Test each product alone because all three pages caution against additive combinations. If a combination is later required, keep order and shear fixed and include the single-additive controls.
Age the liquid formulation and finished film. Recheck clarity/separation, viscosity, foam, craters, gloss, cure, rub, blocking and recoat. For an aqueous 3432 trial, liquid stability is a mandatory gate; for 3032, repeat cure-sensitive properties after aging.
Run a controlled print or coating trial
- Prepare a blank and one product-specific dose ladder.
- Hold resin, pigment, solvent, viscosity, film weight and cure.
- Record wet-film defects, foam/density and drying.
- Condition panels or prints before rub, block and adhesion tests.
- Repeat performance after liquid and finished-film aging.
Measure rub and abrasion without merging them
ASTM D5264 provides a rub comparison for printed materials. ASTM D4060 evaluates abrasion resistance of organic coatings on flat rigid panels. Select the method that matches the substrate and end use.
Pair wear with cure, adhesion, gloss/haze, color, blocking, friction and recoat. A low-friction surface that loses intercoat adhesion is not passing.
Common comparison errors
Calling 3032 quantitatively reactive
The public page does not provide the data needed for a reaction calculation.
Treating 3432 as proven waterborne
Resolve the application-prose and system-table conflict before an aqueous trial.
Inventing a 3501 starting dose
Request current supplier guidance and a measurable endpoint.
Request an evidence-based shortlist
Send resin/system, pigments, crosslinker, cure, substrate, application, film weight, current additives, defect timing, foam data and rub, block, adhesion and recoat requirements. Ask Longchang Chemical to resolve the 3032 reaction data, 3432 water boundary and 3501 dosage before sampling.
