빠른 답변: Buyers choosing between OXE-06, 1206, 그리고 262 for negative photoresist usually get a better first shortlist when they separate a direct LED395 LCD route, a 365 nm ultra-thin colored-system route, 그리고 a broader visible-light or PCB-oriented process window. In Longchang’s current public product set, CHLUMINIT® OXE-06 is the clearest first screen when the buyer needs a product Longchang directly positions for negative photoresist of LCD at LED395 nm with stated tolerance for 35% by weight of carbon black pigment. 광개시제 1206 moves up when the real job is 365 nm curing in colored or black-pigment systems, especially when the film is ultra-thin at 1 to 30 μm. CHLUMINIT® 262 deserves earlier review when the buyer wants a broader visible-light response, a product Longchang positions for photoresist and etch resist for PCB, and a route with stronger handling flexibility through high solubility, low volatility, 그리고 mild smell.
This page is intentionally narrower than the broader 네거티브 포토레지스트 가이드 and more comparison-led than the existing LCD negative photoresist page. The intent here is commercial selection. A buyer is not asking for a general overview of photoresist chemistry. The buyer is asking which of these three Longchang routes should go into the first sample round.
Quick comparison table: OXE-06 vs 1206 vs 262
| 제품 | 최적 첫 번째 적합 | 구매자들이 왜 그것을 후보에 올리는가 | 첫 번째 옵션이 아닐 때 |
|---|---|---|---|
| OXE-06 | LCD negative photoresist routes centered on LED395 nm | Longchang directly states LED395 nm, negative photoresist of LCD, tolerance for 35% by weight of carbon black pigment, and zero VOC emissions. | When the process is clearly centered on 365 nm ultra-thin colored work or a broader PCB-oriented visible-light route. |
| 1206 | 365 nm colored and black-pigment systems, especially ultra-thin films | Longchang states high sensitivity to 365 nm, suitability for colored systems including black pigment systems, tolerance up to 35 wt% carbon black pigment, ultra-thin-film 1 to 30 μm relevance, and use in TFT-LCD color filters, photosensitive inks, and electronic material inks. | When the buyer wants the most direct LCD negative-photoresist wording at 395 nm or needs broader visible-light and PCB-etch-resist flexibility first. |
| 262 | Broader visible-light and PCB-oriented negative-photoresist screening | Longchang says 262 can cure under visible light, lists absorption peaks at 300, 390, and 450 nm, and places it in photoresist and etch resist for PCB with high solubility, low volatility, and mild smell. | When the buyer already knows the job is a tighter 395 nm LCD route or a 365 nm ultra-thin colored display route. |
Why this comparison page is worth having
These three products do not solve the same first-stage buying problem, even though all of them can appear in photoresist conversations. The fastest way to waste sample cycles is to compare them as if they were interchangeable.
- OXE-06 is the direct-route answer when the job is specifically LCD negative photoresist at LED395 nm.
- 1206 is the process-detail answer when 365 nm sensitivity, black-pigment tolerance, and ultra-thin-film behavior drive the decision.
- 262 is the process-flexibility answer when the buyer needs a broader visible-light and PCB-oriented shortlist rather than one narrow display window.
That makes this a legitimate comparison page, not a rewrite of an existing article. The buyer intent here is product-to-product selection inside one technical use family.
When OXE-06 is the better fit
OXE-06 should usually be the first sample when the project is tightly tied to LCD negative photoresist and the curing window is already centered on LED395 nm. Longchang’s current product page is unusually direct here. It does not only describe broad UV curing. It explicitly states LED395 nm and says the product is suitable for negative photoresist of LCD.
- Direct LCD fit: the company page names negative photoresist of LCD directly.
- Clear wavelength fit: the same page calls out LED395 nm.
- 색소 내성 Longchang states tolerance for 35% by weight of carbon black pigment.
- Cleaner processing position: the page also states zero VOC emissions.
If a buyer is trying to reduce qualification noise in an LCD line, that directness matters. OXE-06 is not the broadest option here, but it is the clearest first screen when the process window is already known.
1206이 더 적합할 때
광개시제 1206 deserves earlier review when the real selection pressure is not only LCD wording, but 365 nm sensitivity, black-pigment tolerance, 그리고 ultra-thin-film behavior. Longchang states that 1206 has high sensitivity to 365 nm and is suitable for colored systems, including black pigment systems. The current page also says it can withstand up to 35 wt% of carbon black pigment and is intended for ultra-thin film curing systems from 1 to 30 μm.
That combination is commercially useful for buyers working in display-adjacent or precision-imaging routes where a thicker broad-spectrum answer is not the right first benchmark. Longchang also positions 1206 for TFT-LCD flat panel display color filters, photosensitive inks, 그리고 electronic material inks.
In practice, 1206 should move ahead of OXE-06 when the question becomes, “Which route behaves better in a 365 nm, ultra-thin, black-pigment or colored-system process?” rather than, “Which route is the clearest direct LCD negative-photoresist answer at 395 nm?”
When 262 is the better fit
CHLUMINIT® 262 becomes more attractive when the buyer wants process flexibility instead of a narrow single-window screen. Longchang states that 262 can cure under visible light and lists absorption peaks at 300 nm, 390 nm, and 450 nm. The same page places it in photoresist and etch resist for PCB.
That matters because some buyers are not only screening a display line. They are trying to shortlist a route that can stay practical in broader electronics or PCB-related qualification. Longchang further supports 262 with handling-oriented points such as wide absorption range, good thermal stability, high solubility, low volatility, 그리고 mild smell.
262 is usually not the first answer when the buyer already knows the decision is a strict 395 nm LCD or 365 nm ultra-thin color-resist problem. It becomes more valuable when the real requirement is a wider process envelope with PCB relevance.
How buyers should choose between OXE-06, 1206, and 262
Choose OXE-06 first if:
- the project is explicitly LCD negative photoresist,
- the line is already centered on LED395 nm,
- and stated carbon-black tolerance matters in the same screening step.
Choose 1206 first if:
- 365 nm sensitivity is the real first filter,
- the formulation is colored or black-pigmented,
- or ultra-thin 1 to 30 μm imaging layers are part of the process logic.
Choose 262 first if:
- the buyer wants a broader visible-light-capable route,
- PCB photoresist or etch-resist relevance matters,
- or handling practicality and wider process flexibility are more important than one narrow display window.
Common mistakes to avoid
- Do not compare these three only by chemistry-family labels. Their real difference is process fit.
- Do not ignore wavelength discipline. 395 nm, 365 nm, and broader visible-light logic should not be mixed into one vague sample plan.
- Do not hide pigment burden inside a generic photoresist brief. Carbon-black tolerance changes the shortlist quickly.
- Do not use a broad-process product when the job is already narrow. If the line is clearly LED395 LCD, the direct route should usually be screened early.

자주 묻는 질문
Which photoinitiator is the best first choice for LED395 LCD negative photoresist?
In Longchang’s current public product set, OXE-06 is the clearest first choice because the product page directly states LED395 nm, negative photoresist of LCD, carbon-black tolerance, and zero VOC emissions.
When should 1206 move ahead of OXE-06?
1206 should move ahead when the selection is really about 365 nm sensitivity, ultra-thin 1 to 30 μm films, and colored or black-pigment display-adjacent systems rather than a direct 395 nm LCD route.
Why would a buyer choose 262 instead of 1206?
262 becomes more attractive when the buyer needs a broader visible-light and PCB-oriented process window with handling advantages like high solubility and low volatility, instead of a more narrowly defined 365 nm ultra-thin-film route.
Can one of these products replace all the others across every negative-photoresist job?
No. The better commercial approach is to match the first sample round to the actual process window, pigment burden, film profile, and application family instead of treating the three products as interchangeable.
Next step
If your negative-photoresist project is being slowed by confusion between LCD, colored ultra-thin imaging, and broader PCB process needs, first decide whether the real bottleneck is LED395 LCD fit, 365 nm ultra-thin colored performance, or a broader visible-light PCB route. That usually produces a cleaner first sample plan than comparing OXE-06, 1206, and 262 as if they solve the same job.
