빠른 답변: 구매자 비교 FS-D9013R, FS-D8950BR, 그리고 FS-D8980 usually get the cleanest shortlist when they separate three different first-screen jobs instead of treating every fluorocarbon additive as the same surface-control tool. FS-D9013R should move first when the real problem is persistent anti-cratering pressure, orange peel in solvent-based UV cure또는 silicone-restricted UV primer route where recoating still matters. FS-D8950BR becomes the stronger first route when the buyer wants 바니시 호환성, 반분화구, and a cleaner fit for large-area spraying or multi-color wet-spray workflows. FS-D8980 belongs earlier when the system is more about 장파장 평탄화에 탁월함, 오렌지 껍질 예방, 그리고 spray-flow stability than about the most aggressive crater-fix route.
That is the commercially useful split. These three Longchang products all sit inside solvent-based UV surface-control work, but they do not solve the same buyer problem first.
이 비교를 위한 별도의 페이지가 필요한 이유
롱창은 이미 더 광범위한 페이지를 보유하고 있습니다. fluorine surfactants for surface control, UV 바니시 표면 제어, UV 코팅의 흐름 및 평활도, 그리고 결함 기반 첨가제 선택. But buyers still reach a narrower decision point after those pages: which fluorocarbon additive should be sampled first for this solvent-based UV varnish or primer job?
That is different from asking whether a fluorine route is needed at all. Once the team has already decided the problem sits inside the fluorocarbon lane, the next commercial question is whether the job is mainly about anti-cratering and silicone restriction, spray-application robustness with anti-cratering, 또는 leveling and orange-peel control without the same crater priority.
What these three products have in common, and where they split
Longchang’s current product pages place all three products in 용매 기반 UV 경화 and describe them as fluorocarbon copolymer solutions. All three are tied to 장파장 평탄화에 탁월함 및 오렌지 껍질 예방. That shared positioning is exactly why buyers can waste time if they treat them as interchangeable.
팀이 보다 세부적인 지원 정보를 확인하는 시점부터 분할이 시작됩니다.
- FS-D9013R adds explicit support for 탁월한 분화구 방지, 빠른 레벨링 속도, 재코팅, and use as an 실리콘 첨가제를 사용할 수 없는 경우의 수축 방지 첨가제, plus an important warning about UV vacuum electroplating primer.
- FS-D8950BR adds explicit support for 바니쉬와의 호환성이 좋습니다., 탁월한 분화구 방지적합성 넓은 지역 분무, and control of color channeling between colors after wet spraying and drying.
- FS-D8980 keeps the stronger emphasis on 바니쉬와의 호환성이 좋습니다., 장파장 평탄화에 탁월함, 오렌지 껍질 예방, 그리고 multi-color spray-flow control, but without the same direct anti-cratering claim found on 9013R and 8950BR.
That difference is enough to justify a real comparison page rather than forcing buyers back into a broad additive overview.

When FS-D9013R is the better fit
FS-D9013R should move to the front when the surface problem is still refusing to settle after more ordinary varnish-leveling adjustments, especially in 일반 UV 프라이머 work where 반분화구 및 재코팅 both matter. Longchang’s current product page supports 장파장 평탄화에 탁월함, 오렌지 껍질 예방, 탁월한 분화구 방지, 빠른 레벨링 속도, 그리고 high temperature resistance. The same page also says it 재코팅이 가능할 수도 있습니다 그리고 종종 다음과 같이 사용됩니다. 실리콘 첨가제를 사용할 수 없는 시스템에서 수축 방지 첨가제.
That makes 9013R the strongest first route when:
- the project is inside a solvent-based UV primer or varnish window
- the panel still shows persistent crater pressure or anti-shrinkage problems
- 팀에게는 지원되는 경로가 필요합니다. 실리콘 제한 systems
- recoating still matters in the supported application window
The caution matters just as much as the strengths. Longchang explicitly says 9013R is useful in common UV primer anti-cratering work without affecting recoating, but also says it is UV 진공 전기 도금 프라이머에는 적용되지 않습니다. because it will affect recoating. That limitation is commercially important and should be screened early, not after scale-up.
When FS-D8950BR is the better fit
FS-D8950BR becomes more attractive when the buyer wants a fluorocarbon route that still keeps 바니시 호환성 visible while adding 탁월한 분화구 방지 and a stronger large-area spray story. Longchang’s current page supports 바니쉬와의 호환성이 좋습니다., 장파장 평탄화에 탁월함, 오렌지 껍질 예방, 그리고 탁월한 분화구 방지. It also says the product is 넓은 면적에 분무하기에 적합합니다. and can help prevent and eliminate color channeling between colors after wet spraying and drying.
That pushes 8950BR ahead when:
- the project is closer to a spray-finish varnish or decorative UV coating job
- the buyer still needs 반분화구, but does not need the same silicone-restricted primer logic as 9013R
- the production route includes 넓은 지역 분무 또는 multi-color wet-spray sequencing
- the team wants a supported fluorocarbon route that is explicit about 바니시 호환성
Longchang also says 8950BR has 거품 억제 없음. That is a useful reminder that buyers should not expect this route to solve an air-management problem that actually belongs in a 소포제 screen.
When FS-D8980 is the better fit
FS-D8980 belongs earlier when the first question is more about clean leveling and spray-flow behavior than about the strongest crater-fix route. Longchang’s current page supports 바니쉬와의 호환성이 좋습니다., 장파장 평탄화에 탁월함, 오렌지 껍질 예방적합성 넓은 지역 분무, and reducing color channeling between colors after wet spraying and drying. The page also gives a slightly lower suggested addition range of 0.05-0.8%, which can be useful when buyers want a narrower first dose screen.
That makes 8980 a cleaner first route when:
- the team mainly needs spray-flow uniformity 및 오렌지 껍질 예방
- good 바니시 호환성 still matters
- the panel is not clearly dominated by the same crater pressure that points harder toward 9013R or 8950BR
- the buyer wants to start with a lower-use fluorocarbon route before escalating
In short, 8980 is usually the more defensible first screen when the problem still looks like a leveling-and-spray-behavior issue rather than a crater-heavy rescue job.
구매자가 샘플을 요청하기 전에 선택해야 할 사항
1. Ask whether the real problem is crater-heavy or leveling-heavy
If the panel is still dominated by anti-cratering pressure, start by comparing 9013R and 8950BR more seriously. If the panel is mainly about flow, orange peel, and spray uniformity, 8980 deserves earlier attention.
2. 프로세스 창을 계속 표시해 두십시오.
All three products sit in solvent-based UV cure, but the job type still matters. UV primer, decorative varnish, and large-area wet spray do not always deserve the same first sample.
3. Do not ignore recoating reality
9013R has a strong supported place in common UV primer work, but Longchang’s UV vacuum electroplating primer warning is real and should be treated as a hard screen.
4. Separate foam control from surface-control chemistry
8950BR and 8980 both note no foam inhibition. If the actual defect is trapped air or microbubble behavior, move that discussion back toward a defoamer route instead of asking a fluorocarbon additive to do the wrong job.
5. Start with the minimum practical dose window
Longchang’s supported addition ranges are useful for tightening the first lab round. Buyers usually learn faster from a controlled low-to-mid dose screen than from jumping straight to the top of the range.

자주 묻는 질문
Which product is the best first screen for UV primer anti-cratering?
When the project is a supported common UV primer route and recoating matters, FS-D9013R is often the strongest first screen because Longchang explicitly positions it around anti-cratering, fast leveling, and silicone-restricted primer logic. But it should not be used for UV vacuum electroplating primer.
When should buyers start with FS-D8950BR instead of FS-D9013R?
Start with FS-D8950BR earlier when varnish compatibility, large-area spraying, and anti-cratering all matter, but the project does not specifically depend on 9013R’s silicone-free UV primer positioning.
When does FS-D8980 make more sense than the other two?
FS-D8980 makes more sense when the first problem is mostly leveling, orange-peel prevention, and spray-flow behavior, and the panel is not clearly calling for the strongest crater-control route.
이 세 제품은 서로 호환되나요?
No. They share a solvent-based UV fluorocarbon base and overlap in leveling language, but their current Longchang-supported roles are different enough that buyers should not treat them as plug-and-play substitutes.
보다 엄선된 1차 후보 명단이 필요하신가요?
If your UV varnish or UV primer team is stuck between crater control, spray-flow stability, orange-peel prevention, and recoating limits, define the real bottleneck first: silicone-restricted anti-cratering, varnish-compatible anti-cratering in spraying, 또는 leveling-led spray uniformity. That usually points to the right Longchang fluorocarbon route much faster than screening all three as if they solved the same problem.
