Réponse rapide : acheteurs travaillant sur revêtements industriels à base d'eau usually move faster when they separate three different first-screen jobs instead of throwing several silicone additives into the same trial. CHLUMIWE® 3071 should move first when the immediate problem is substrate wetting and fast spreading on difficult industrial surfaces. CHLUMILE® 3345 deserves the earlier screen when the lab needs a équilibre plus large d'humidification et de nivellement instead of only one wetting push. CHLUMIAF® 094 belongs earlier when the coating already has the right resin route but persistent foam, microbubbles, or air-release problems keep ruining the film.
That is the commercially useful split. This page is not another broad coatings-additives article. It is a system-specific CHLUMICRYL® selection page for buyers who already know the project is a waterborne industrial coating and need a cleaner first shortlist.
Why waterborne industrial coatings deserve their own additive page
Longchang possède déjà des pages en direct pour revêtements pour bois à base d'eau, waterborne epoxy anti-sticking additives, revêtements anticorrosion, and the broader defect-driven additive guide. Those pages solve different buyer questions.
A waterborne industrial coating project often creates a narrower first-screen decision: is the main bottleneck substrate wetting, smoother leveling after wetting, or foam collapse and air release? That question shows up across general industrial coatings, protective coatings, and similar factory-applied waterborne systems. It deserves its own page because the buyer job is more system-specific than the wood page and less overlap-heavy than another generic defect article.
What makes these three routes different
- CHLUMIWE® 3071 is positioned by Longchang as an agent mouillant organosilicone. The company-supported page gives it 0,1% à 1,0% dosage guidance, allows addition during grinding, stirring, or after production, and supports use in Systèmes à base d'UV, de solvants et d'eau. Its listed watchpoint is important for waterborne work: it may stabilize foam dans les systèmes à base d'eau.
- CHLUMILE® 3345 est positionné directement comme un agent mouillant et nivelantLongchang soutient également 0,1% à 1,0% dosage, addition during grinding, stirring, or after production, compatibility with Systèmes à base d'UV, de solvants et d'eau, and notes that adding co-solvents such as éther méthylique de dipropylène glycol peut amplifier l'effet.
- CHLUMIAF® 094 est le voie d'abord antimousseLongchang le soutient pour systèmes à base d'eau uniquement, with dosage guidance at 50 à 500 ppm, and explicitly says it should normally be diluer avant utilisation rather than dropped into the working solution at full strength.
That is enough separation to help a buyer choose a smarter first sample path.
Tableau comparatif rapide : quel itinéraire mérite la première place ?
| Buyer priority in waterborne industrial coatings | Meilleur premier itinéraire | Pourquoi cela devrait être la première chose à faire | Point de surveillance principal |
|---|---|---|---|
| Difficult substrate wetting, poor spread, or weak first-contact flow on industrial surfaces | CHLUMIWE® 3071 | Longchang positions it as an organosilicone wetting agent with low surface-tension behavior and broad system fit | In water-based systems it may stabilize foam, so wetting gains must be checked alongside bubble risk |
| The coating needs wetting help, but the real commercial target is smoother, more even laydown instead of wetting alone | CHLUMILE® 3345 | Longchang positions it directly as a wetting-and-leveling route and notes that co-solvent use can strengthen the effect | Buyers still need to verify whether the project needs broader leveling balance or a stronger defoaming intervention |
| Persistent foam, microbubbles, or air-release defects are blocking acceptable film quality | CHLUMIAF® 094 | Longchang supports it as a waterborne-coating defoamer with ppm-level use and a water-only operating window | It should generally be pre-diluted before use, and it is not a substitute for a true wetting or leveling route |
Quand CHLUMIWE® 3071 est le meilleur premier choix
3071 should move to the front when the coating team is failing at the tout premier contact. If the waterborne system does not spread cleanly on the substrate, keeps pulling back, or struggles to wet a harder industrial surface, a wetting-first route is often more informative than jumping straight to a broader surface package.
Longchang supports 3071 as a polyether-modified polysiloxane wetting agent with a recommended dosage of 0,1% à 1,0%. The page allows addition during grinding, stirring, or after production, and supports use in water-based, solvent, and UV systems. For this page, the key point is not that it fits every system. The key point is that it gives buyers a clear wetting-first benchmark inside a waterborne industrial-coating project.
- Best first-screen use: harder-to-wet industrial substrates and early spread problems
- Dosage guidance: 0,1% à 1,0% de la formulation totale
- Addition logic: during grinding, stirring, or after production
- Main caution: in water-based systems it may stabilize foam, so do not judge it only by wetting improvement
In short, 3071 is the better first move when the coating is not making good enough contact with the substrate.
Quand CHLUMILE® 3345 est le meilleur premier choix
3345 deserves the earlier screen when the buyer is not only chasing substrate wetting. It is the stronger first route when the coating must also lay down more evenly after it wets. Longchang’s company-supported positioning is more specific here because the product is named and framed directly as a agent mouillant et nivelant.
The supported page gives 3345 the same 0,1% à 1,0% dosage range, broad water-based, solvent, and UV applicability, and flexible addition timing during grinding, stirring, or later addition. Longchang also notes that co-solvents such as éther méthylique de dipropylène glycol can enhance the effect, which makes it a practical screening route when the project needs a more refined wetting-plus-leveling balance instead of only a stronger surfactant push.
- Best first-screen use: waterborne industrial finishes that need smoother laydown after wetting
- Dosage guidance: 0,1% à 1,0% de la formulation totale
- Addition logic: during grinding, stirring, or after production
- Practical note: co-solvent adjustment may improve the effect during development work
So 3345 is the cleaner first benchmark when the buyer wants balanced wetting and leveling, not only stronger wetting.
Quand CHLUMIAF® 094 est le meilleur premier choix
094 should move ahead when the project already has a plausible wetting route but the film keeps failing because of persistent foam, entrained air, or microbubble-type defects. That is a different job from surface wetting. It is also one that can waste a lot of development time if the team keeps testing more surfactants before solving the foam problem.
Longchang supports 094 as a polyether silicone defoamer pour systèmes à base d'eau uniquement. Its recommended dosage is much lower than the wetting or leveling routes, at 50 à 500 ppm based on total formulation. The company page also states that direct full-strength addition to the working solution is generally not conducive to dispersion, so the product should usually be diluted below 60% and then further diluted with water to prepare a working solution for use.
- Best first-screen use: persistent foam, microbubbles, or poor air release in waterborne industrial coatings
- Dosage guidance: 50 to 500 ppm based on total formulation
- Preparation rule: dilute before use rather than adding it full strength into the working solution
- System fit: systèmes à base d'eau uniquement
That makes 094 the better first move when the project is failing because of contrôle de la mousse, not because of a missing wetting or leveling route.
Comment les acheteurs doivent choisir avant de demander des échantillons
1. Start with the first visible failure
If the coating cannot wet the substrate cleanly, start with 3071. If it wets but still does not level into an even film, move 3345 earlier. If the film quality is being destroyed by foam or trapped air, 094 should move first.
2. Keep the operating window visible
3071 and 3345 both have broader system fit on the company pages, but 094 is explicitly a à base d'eau uniquement route. That alone helps keep early screening more disciplined.
3. Do not confuse related surface problems with the same additive job
Wetting failure, leveling failure, and foam failure often show up on the same panel, but they are not the same selection problem. Buyers usually get faster answers when they identify which one is the first cause.
4. Use the watchpoint, not just the headline benefit
3071 may stabilize foam in water-based systems. 3345 may need co-solvent support to deliver the best balance. 094 should be diluted before use. Those practical notes often decide the better first route more than the headline product family.
5. Keep the first round tight
For most waterborne industrial-coating buyers, one wetting-first route, one wetting-and-leveling route, and one defoamer-first route teach more than an overloaded first panel with too many overlapping additives.

FAQ
Which additive should I screen first if a waterborne industrial coating will not wet the substrate well?
Start with CHLUMIWE® 3071 when the main early failure is poor wetting or spreading on a difficult industrial surface.
When is 3345 a better first route than 3071?
3345 is usually the better first route when the project needs wetting support but the real commercial target is more even film laydown and broader leveling balance.
When should 094 move ahead of wetting or leveling additives?
094 should move ahead when persistent foam, entrained air, or microbubble defects are the main barrier to acceptable film quality in a waterborne system.
Can 094 replace a wetting or leveling additive?
No. 094 is a defoamer-first route. It helps solve a different problem and should not be treated as a substitute for true wetting or leveling selection.
Need a faster shortlist for waterborne industrial coatings?
If your team is stuck between stronger wetting, smoother wetting plus levelinget direct foam control, define the real first-screen job before you ask for samples. That usually shows much faster whether CHLUMIWE® 3071, CHLUMILE® 3345, or CHLUMIAF® 094 deserves the first round.
