Jawaban singkat: buyers should not treat CHLUMIAG® 5005, CHLUMIAG® 5005-60, Dan CHLUMIFE® 3388 as interchangeable PU-leather additives. 5005 should move up first when the project needs a more deliberate permanent hand-feel plus stain-resistance route in solvent-side or oil-based systems. 5005-60 becomes more relevant when the team wants a reactive hydroxyl-system route that is also positioned as an anti-graffiti or baking-paint hand-feel additive. 3388 deserves earlier review when the finish target is a delicate dry touch for PU leather and the buyer also cares about not damaging gloss or transparency in the gloss layer.
This page is not another broad anti-graffiti overview. It is a narrower buyer-comparison page for leather-finishing and specialty-coating teams who already know the project lives in the hand feel, stain resistance, easy cleanability, or release-performance zone and need a faster first shortlist.
Why this comparison matters after the broader CHLUMICRYL® additive pages
Longchang sudah memiliki halaman aktif untuk Pelapis dan Aditif Tinta CHLUMICRYL®, aditif anti-grafiti, and several coating-surface decision pages. But buyers working on PU leather and specialty finishing often reach a tighter question after that: which product should be screened first when the surface has to feel better, resist staining more reliably, or release more cleanly without ruining the finish?
That is a different commercial decision from a broad function page. In practical finishing work, a route that gives durable stain resistance is not automatically the best route for soft dry touch, and a leather-specific feel modifier is not automatically the best benchmark when the project is really a reactive anti-graffiti or baking-paint problem.
Quick comparison table: which route deserves the first screen?
| Observed buyer priority | Rute pertama terbaik | Why it belongs first | Titik pengawasan utama |
|---|---|---|---|
| Permanent hand feel plus stain resistance in solvent or oil-based finishing systems | CHLUMIAG® 5005 | Longchang supports it around hand feel, stain resistance, resin modification, and direct use in two-component polyester, polyurethane, and acrylate systems | Not a water-based route, and the loading window changes by target job |
| Reactive hydroxyl-system hand-feel and anti-graffiti route for baking-paint style finishing | CHLUMIAG® 5005-60 | Longchang positions it with reactive hydroxyl functionality that can crosslink into the polymer network and stay fixed at the coating surface | Best treated as a reactive finish-design route, not a generic drop-in slip additive |
| PU leather dry hand feel and release performance without sacrificing gloss-layer clarity | CHLUMIFE® 3388 | Longchang directly positions it as a PU-leather hand-feel agent that gives a delicate dry touch without affecting transparency and gloss of the gloss layer | Leather-finish logic is narrower than a broad anti-graffiti or industrial easy-clean route |
When CHLUMIAG® 5005 is the better first move
5005 belongs earlier when the buyer wants one route that can push hand feel, stain resistance, Dan resin-side integration together instead of treating those as separate decisions. Longchang supports 5005 as a polisiloksan termodifikasi multi-komponen with three different commercial use windows:
- Permanent hand feel: 0.2% to 1%
- Stain resistance: 2% to 6%
- Resin modification: 1% to 6%
Longchang also states that 5005 can be added during polymerization as an organosilicon modifier or added directly into two-component polyester, polyurethane, and acrylate systems. The same product page explicitly marks it as suitable for oil-based dan berbasis pelarut sistem, tetapi not for water-based systems.
That makes 5005 the cleaner first benchmark when:
- the project is already inside a solvent-side or oil-based finish-design window,
- the buyer wants a durable hand-feel route instead of a temporary surface-only effect,
- stain resistance matters as much as touch, or
- the team wants a route that can also be considered for resin modification rather than only late-stage additive use.
Kapan CHLUMIAG® 5005-60 merupakan langkah awal yang lebih baik?
5005-60 should move ahead when the commercial logic is more specifically about a reactive hydroxyl-system finish. Longchang positions 5005-60 as an aditif anti-grafiti silikon organik, agen silikon organik untuk meningkatkan rasa sentuhan, agen sentuhan tangan cat panggang, Dan aditif tahan abrasi. The company page also states that it contains reactive hydroxyl functional groups, adalah cocok untuk sistem reaksi hidroksil, dan bisa ikatan silang ke dalam struktur jaringan polimer, which helps fix it permanently to the coating surface.
That matters because some buyers are not just trying to make the top layer feel nicer. They are trying to build a finish that holds onto the effect more reliably in a reactive system window.
5005-60 deserves earlier review when:
- the finish design already lives in a hydroxyl-functional reactive system,
- the buyer wants a route explicitly framed around anti-graffiti plus hand feel,
- baking-paint or similarly reactive coating logic is part of the project, or
- the team wants a more direct comparison against a conventional hand-feel-only route.
The practical caution is simple: this is best treated as a reactive finishing route, not as a generic slip or anti-blocking additive to be sampled without system context.
When CHLUMIFE® 3388 is the better first move
3388 belongs earlier when the surface target is more specifically PU leather feel control and the buyer wants to protect the visual quality of the gloss layer at the same time. Longchang’s product page positions 3388 as a specially modified organopolysiloxane used as a hand-feel agent for PU leather. The same page states that it can provide a delicate and dry hand feel without affecting the transparency and gloss of the gloss layer. Longchang also ties it to leather finishing and positions it as a polyurethane solvent-based release agent.
That makes 3388 the cleaner first route when:
- the buyer is really solving a PU leather topcoat hand-feel problem,
- dry touch matters more than broader anti-graffiti language,
- the finish still has to preserve gloss-layer clarity and appearance, atau
- release behavior is part of the leather-finishing workflow.
3388 is therefore not just a weaker version of 5005 or 5005-60. It belongs in a more leather-specific lane.
Bagaimana pembeli harus memilih di antara ketiga jalur ini?
1. Start with the real finish KPI
If the project is mainly about permanent hand feel plus stain resistance, 5005 deserves earlier attention. If it is more clearly a reactive hydroxyl-system and anti-graffiti-style finish-design problem, 5005-60 should move up. If it is a PU leather feel and gloss-layer protection project, 3388 is usually the cleaner first route.
2. Separate reactive surface design from leather-touch tuning
5005 and 5005-60 both live closer to durable reactive surface design logic. 3388 lives closer to PU leather finishing and release logic. That is a commercially useful split, not a wording nuance.
3. Keep the system boundary visible
5005 is explicitly solvent or oil-based and not water-based. 5005-60 is best read through its hydroxyl-reactive system fit. 3388 is clearly tied to solvent-based polyurethane leather finishing. If the system fit is wrong, the hand-feel discussion gets noisy fast.
4. Do not confuse dry feel with stain resistance
A drier touch does not automatically mean the strongest stain-resistance route, and a stain-resistance route does not automatically give the most elegant leather feel. Buyers should test the real commercial target instead of assuming those outcomes always travel together.
5. Keep the first sample round short
For most buyers, the cleanest first round is one route for permanent hand feel and stain resistance, satu rute untuk reactive hydroxyl-system finishing, dan satu rute untuk PU leather dry-feel and release. That usually teaches more than comparing too many overlapping additives at once.

PERTANYAAN YANG SERING DIAJUKAN
Which additive should I screen first for PU leather dry hand feel?
If the real target is a delicate dry touch in PU leather without harming gloss-layer clarity, 3388 deserves earlier review because Longchang directly positions it for that job.
When is 5005 a better first route than 5005-60?
5005 is the better first route when the buyer wants a more explicit permanent hand-feel, stain-resistance, or resin-modification route in solvent-side or oil-based systems. 5005-60 moves up when the project is more clearly a reactive hydroxyl-system and anti-graffiti-style finishing decision.
Can 5005 be used in water-based systems?
No. Longchang explicitly marks 5005 as suitable for oil-based and solvent-based systems and not suitable for water-based systems.
Is 3388 just another anti-graffiti additive?
No. Longchang positions 3388 more specifically as a PU-leather hand-feel and release route, with the added advantage that it can preserve gloss-layer transparency and gloss while delivering a dry feel.
Need a faster shortlist for PU leather finishing?
If your program is stuck between better touch, more reliable stain resistance, Dan cleaner release or gloss-layer preservation, stop treating all organosilicone additives as the same first move. Start by separating permanent hand feel, reactive finish design, Dan PU leather dry-feel finishing. That usually shows much faster whether 5005, 5005-60, or 3388 deserves the first sample round.
