快速回答： buyers comparing CHLUMIAG® 3367, CHLUMIAG® 3500， 和 CHLUMIAG® 3565 usually get a cleaner shortlist when they separate three different first-screen jobs instead of treating every reactive leveling additive as the same silicone tool. CHLUMIAG® 3367 should move first when the real need is cross-system compatibility, resin-modification flexibility, or a leveling route that can also sit inside PU handling logic. CHLUMIAG® 3500 belongs earlier when the buyer wants an explicit UV-cured leveling route with a straightforward 0.05% 至 1% first-screen window and can manage the product’s light-protected, heat-sensitive storage discipline. CHLUMIAG® 3565 deserves earlier review when water dispersibility or oil solubility matters, but the team is willing to screen the product’s stated 针孔风险 早期的。
That is the commercially useful split. All three Longchang products are supported across 紫外、溶剂和水基体系, but they do not solve the same buyer problem first.
为什么这项比较值得单独成页？
龙昌已经有了更宽泛的页面 leveling additives for coatings and inks, UV coating flow and leveling， 和 缺陷驱动的添加剂选择. Those pages help buyers decide whether a leveling route belongs in the shortlist. This page answers the narrower commercial question that comes after that: which reactive or cross-system leveling route should be sampled first?
That is a different decision from asking whether the defect is flow-out, wetting, crater pressure, or trapped air. Once the team has already decided the job belongs inside the leveling lane, the next useful split is usually about compatibility, addition method, storage constraints, resin-modification fit， 和 risk factors such as pinholing.
What these three products share, and where they split
Longchang’s current product pages place all three products in 紫外线, solvent， 和 水性 systems. That shared positioning is exactly why buyers can waste time if they treat them as plug-and-play substitutes.
The split starts when the team checks the narrower supported details:
- CHLUMIAG® 3367 is positioned around system compatibility, with dosage guidance that separates solvent-based screening from resin-modification 和 水性 use. Longchang also says it can be added together with the polyol during polyurethane prepolymerization or later.
- CHLUMIAG® 3500 is explicitly titled as a UV-cured leveling agent, with a straightforward 0.05% 至 1% recommendation and a clear storage watchpoint: it must be kept sealed, protected from light, and protected from high temperatures.
- CHLUMIAG® 3565 is supported as a polyether-modified polysiloxane 那是 可分散于水中 和 油溶性, should be added before the curing agent, and carries an explicit pinhole-risk warning.
That difference is enough to justify a real buyer-selection page instead of sending people back to a broad function article.
Quick comparison table: CHLUMIAG® 3367 vs 3500 vs 3565
| 购买因素 | CHLUMIAG® 3367 | CHLUMIAG® 3500 | CHLUMIAG® 3565 |
|---|---|---|---|
| Main supported systems | 紫外、溶剂和水基 | 紫外、溶剂和水基 | 紫外、溶剂和水基 |
| 首先是什么推动了它的发展 | Compatibility-first selection, PU or resin-modification flexibility, and broad cross-system screening | Explicit UV-cured leveling route with simple first-screen dosage logic | Water-dispersible or oil-soluble route with early pinhole-risk discipline |
| 建议用量 | 溶剂体系中树脂用量为0.05%至1%；树脂改性用量为0.5%至5%；水基体系中树脂用量为0.5%至5%。 | 总配方量为 0.05% 至 1% | 总配方量为 0.05% 至 1% |
| 加法逻辑 | 可在聚氨酯预聚合过程中与多元醇一起添加，也可稍后添加，或稀释后添加以便于添加。 | Can be added at any stage of production or later | Add before adding the curing agent and stir thoroughly |
| 重要观察点 | Compatibility is prioritized, so the feel is described as slightly less refined | Store sealed, light-protected, and away from high temperature | May cause pinholes and should be tested before industrial production |
When CHLUMIAG® 3367 is the better fit
CHLUMIAG® 3367 should move to the front when the buyer’s first priority is not only leveling, but how widely the same route can travel across systems and processing styles. Longchang supports it in 紫外、溶剂和水基体系, gives a split dosage structure for 溶剂体系, water-based systems， 和 resin modification, and says it can be introduced during 聚氨酯预聚物 or later.
Longchang also names application scenarios such as industrial protective coatings, architectural coatings, wood or furniture coatings, printing inks， 和 PU. That makes 3367 commercially useful when one project or one customer line is still bridging several related coating windows.
- 最佳匹配： buyers who want one reactive leveling route to screen across more than one formulation boundary
- 主要优势： broader compatibility and explicit resin-modification flexibility
- 主要观察点： the current page says compatibility is prioritized, so the feel is slightly less refined than a feel-first substitute route
In short, 3367 is the more defensible first screen when the lab wants a compatibility-first benchmark instead of the narrowest specialized route.
When CHLUMIAG® 3500 is the better fit
CHLUMIAG® 3500 deserves earlier review when the project is being framed first as a UV-cured leveling job and the buyer wants a simple, direct first sample plan. Longchang explicitly titles it as a UV-cured leveling agent, supports it across 紫外、溶剂和水基体系, and gives a straightforward recommended dosage of 0.05% 至 1% of total formulation.
That matters because buyers often want one route that is easy to explain to production and easy to screen in a narrow low-dose window before a larger additive package is considered.
- 最佳匹配： buyers who want an explicit UV-cured leveling route with simple low-dose screening logic
- 主要优势： clean positioning around UV-cured leveling instead of broader compatibility storytelling
- 主要观察点： the current page requires sealed, light-protected storage and protection from high temperature
That storage discipline is commercially important. A route that looks attractive on paper can still become inconvenient if the real plant handling window is loose.
当 CHLUMIAG® 3565 更合适时
CHLUMIAG® 3565 belongs earlier when the buyer wants a leveling route that is explicitly 可分散于水中 和 油溶性, while still staying inside a cross-system window. Longchang supports it in 紫外、溶剂和水基体系, recommends a 0.05% 至 1% dosage range, and says it should be added before the curing agent 充分搅拌。
What makes 3565 commercially distinct is the watchpoint. Longchang explicitly says the risk of this product is that it 可能导致针孔, and that users should pay close attention to this when selecting similar products and test before industrial production.
- 最佳匹配： buyers who need water dispersibility or oil solubility and can control the addition sequence carefully
- 主要优势： useful cross-system handling language for formulations that still bridge aqueous and oil-side logic
- 主要观察点： pinhole risk should be screened early, not after scale-up
That makes 3565 the smarter first choice when the handling route is attractive enough to justify a more disciplined defect-risk check.
买家在索取样品前应该如何选择
1. Start with whether compatibility or specialization matters more
If the project still needs one route that can move across solvent, water-based, PU, or resin-modification work, 3367 deserves earlier attention. If the job is already framed more narrowly as a UV-cured leveling route, 3500 is cleaner.
2. Keep the addition sequence visible
3565 explicitly belongs before the curing agent. 3367 carries PU prepolymerization logic. 3500 is simpler about stage-of-addition. Those differences are not minor when plant transfer matters.
3. Use the real watchpoint, not just the headline benefit
3367 warns that feel is slightly less refined because compatibility is prioritized. 3500 needs better storage discipline. 3565 may cause pinholes. Those are the practical reasons one route beats another in a real buying decision.
4. Do not confuse cross-system fit with identical behavior
All three products are supported across UV, solvent, and water-based systems, but that shared system fit does not make their handling, risk profile, or selection logic the same.
5. Keep the first screen small
For many buyers, the cleanest first round is one compatibility-first route, one explicit UV-cured route, and one pinhole-watch cross-system route. That usually teaches more than loading the first panel with too many overlapping leveling candidates.

常见问题
Which product is the better first screen when one line needs solvent, water-based, and PU flexibility?
Usually CHLUMIAG® 3367, because Longchang supports it across UV, solvent, and water-based systems and also gives explicit polyurethane prepolymerization and resin-modification handling logic.
When should buyers start with CHLUMIAG® 3500 instead of 3367?
Start with 3500 earlier when the project is already framed as a UV-cured leveling job and the team wants a straightforward 0.05% to 1% first-screen route with simpler addition-stage language.
What makes CHLUMIAG® 3565 different from the other two?
Its current Longchang page makes water dispersibility, oil solubility, addition before curing agent, and pinhole-risk control much more explicit, which gives it a different selection role even though the system window overlaps.
Are these three products interchangeable because they all fit UV, solvent, and water-based systems?
No. They share a broad system window, but the supported selection logic, addition method, and watchpoints are different enough that buyers should not treat them as drop-in substitutes.
Need a tighter reactive-leveling shortlist?
If your coatings or inks team is stuck between broad compatibility, a narrower UV-cured route, and a water-dispersible option with more defect-risk discipline, define the real first-screen job before asking for samples. That usually points to 3367, 3500, or 3565 much faster than screening them as if they solved the same problem.
