Jawaban singkat: pembeli sedang mengerjakan wood varnishes usually get to a better first shortlist when they stop asking for one additive to solve every surface issue and instead separate three different jobs. CHLUMIFE® 3370 should move first when the project is clearly solvent or UV-side, water-based compatibility is unnecessary, and the buyer wants a more feel-focused silicone route. CHLUMILE® 3432 deserves the earlier screen when the team needs a broader leveling, smoothness, slip, and anti-blocking route for a cleaner-looking varnish film. CHLUMIAG® 3501 belongs earlier when the film already looks directionally acceptable but the buyer still needs a stronger anti-sticking and downstream handling route.
That is the commercially useful split. This page is not a return to the older photoinitiator cluster, and it is not a duplicate of Longchang’s already-live pelapis kayu berbahan dasar air atau 2K PU topcoat pages. It is a new CHLUMICRYL® application page for buyers who need a tighter shortlist for wood varnish feel, surface laydown, Dan handling after film formation.
Why wood varnishes deserve their own additive page
Wood varnish work often gets judged on more than one performance signal at the same time. The buyer may want a smoother or more premium hand feel, but the same film still has to lay down cleanly, avoid obvious surface defects, and keep enough handling stability for conversion, packing, or downstream use. In general industry practice, that means teams often need to separate a feel-focused route from a broader leveling-and-slip route, and both from a more specific anti-sticking route.
Longchang already has live support pages for the broader Pelapis dan Aditif Tinta CHLUMICRYL® hub, plus pages for pelapis kayu berbahan dasar air, 2K polyurethane topcoats, soft-touch coatings, Dan slip, mar resistance, and printability. Those pages help buyers understand the larger branch logic. This page answers the narrower B2B question that comes up sooner in wood-finishing labs: which additive route deserves the first sample round when the varnish still needs better feel, cleaner laydown, or more reliable anti-sticking behavior?
What the current company-supported evidence actually separates
- CHLUMIFE® 3370 is supported as an organosilicon feel agent dan silicone surfactant dengan 0.05% to 3% recommended dosage. Longchang supports it for Sistem UV dan sistem pelarut, while explicitly marking water-based systems as not applicable. The product can be added at any stage or later, can be diluted with alkanes or aromatics, and is described as a waxy solid with an initial melting point of at least 50°C. Longchang’s current public wood-varnish application tables also place 3370 inside the wood varnish, wood coating, and furniture coating branch.
- CHLUMILE® 3432 is supported as an organosilicone leveling agent and surfactant with 0,05% hingga 1,0% recommended dosage. Longchang supports any-stage addition, optional dilution before use, and applicability across UV, pelarut, Dan sistem berbasis air. Current Longchang-controlled product information and application routing place it around penyamarataan, kelancaran, tergelincir, anti-pemblokiran, wetting, Dan anti-kawah work. The same public wood-coating routing tables keep 3432 in the wood-varnish branch, which is enough support for a buyer-selection page without inventing narrower unsupported claims.
- CHLUMIAG® 3501 didukung sebagai polisiloksan termodifikasi multi-komponen that can be added at any stage or later and is supported across UV, pelarut, Dan sistem berbasis air. Longchang directly positions it inside anti-sticking-agent use together with broader printing-ink, overprint-varnish, and release-coating work. Longchang’s current public wood-varnish application tables also place 3501 in the wood varnish, wood coating, and furniture coating branch, which makes it a reasonable handling-first route for buyers who have already moved beyond simple leveling correction.
That is enough company-supported separation to build a real buyer page. External research was used only conservatively for general framing that wood-finishing additive decisions often split into surface feel, film appearance and leveling, Dan blocking or handling stability, rather than one generic silicone story.
Tabel perbandingan singkat: rute mana yang layak ditampilkan di layar pertama?
| Buyer priority | 3370 | 3432 | 3501 |
|---|---|---|---|
| Main first-screen job | Solvent or UV feel-focused varnish routing | Broader leveling, smoothness, slip, and anti-blocking balance | Anti-sticking and downstream handling route |
| Supported dosage | 0.05% to 3% | 0,05% hingga 1,0% | Current public summary used here emphasizes system fit and stage flexibility more clearly than a visible dosage band |
| System window | UV and solvent only | UV, solvent, water-based | UV, solvent, water-based |
| Logika penambahan | Any stage or later addition, with alkane or aromatic dilution possible | Any stage, optional dilution before use | Any stage or later addition |
| Best use when | The buyer wants a clearer feel route in non-waterborne wood varnish work | The varnish reaches the surface but still needs cleaner laydown, smoother appearance, or better slip and anti-blocking balance | The film already looks directionally acceptable but handling or anti-sticking performance still is not stable enough |
| Titik pengawasan utama | Water-based systems are not supported, and waxy-solid handling should be planned early | Use it when the real job is surface appearance and laydown balance, not as a substitute for a handling-first route | Use it when the project has already moved into anti-sticking and handling questions, not when first-layer leveling is still the main bottleneck |
When CHLUMIFE® 3370 is the better first move
3370 deserves earlier review when the buyer is already committed to a solvent or UV wood varnish route and wants a more clearly feel-focused additive path. Longchang’s current public product information makes the boundary unusually clear by supporting 3370 in pelarut dan UV systems while explicitly excluding berbasis air gunakan.
3370 is usually the better first route when:
- the project does not need to keep a water-based option open,
- the buyer wants to improve feel without turning the first trial into a broad multi-function screen,
- the lab is comfortable planning for a waxy-solid additive, atau
- the wood varnish sits in a furniture or clear-finish route where touch and surface feel matter commercially.
This is the cleaner first path when the real question is which non-waterborne varnish route gives the better feel-first benchmark?
When CHLUMILE® 3432 is the better first move
3432 should move up first when the varnish already reaches the surface but still does not lay down cleanly enough. This is the stronger route when the visible film still needs better penyamarataan, kelancaran, tergelincir, anti-pemblokiran, atau anti-cratering balance.
That distinction matters in wood-finishing work because some films do not fail on chemistry family first. They fail on how the cured or dried varnish actually looks. Longchang’s current product information supports 3432 precisely in that middle lane between first contact and downstream handling.
3432 is usually the better first route when:
- the wood varnish already wets directionally well enough but still looks rough or less even than expected,
- the buyer wants a broader appearance-control route rather than a feel-only route,
- blocking or drag marks seem linked to laydown quality more than to a dedicated anti-sticking package, or
- the team wants one benchmark that can still travel across UV, solvent, and water-based branches later.
This is often the more practical first move when the buyer is asking not only how will it feel? but also how cleanly will it lie down on the wood surface?
When CHLUMIAG® 3501 is the better first move
3501 should move ahead first when the project has already gone beyond a pure appearance discussion and the buyer now needs a broader anti-sticking and handling route. This is the cleaner choice when the varnish film already looks directionally acceptable, but contact, packing, or surface handling still is not stable enough for the intended wood-finishing process.
Longchang directly positions 3501 in anti-sticking-agent use and keeps it open across UV, solvent, and water-based systems with stage-flexible addition. In practical buyer terms, that makes it the stronger first benchmark when the lab is no longer trying to solve only leveling or feel, but a more downstream handling question.
3501 is usually the better first route when:
- the film appearance is already directionally acceptable,
- the buyer wants a route more closely tied to anti-sticking behavior than to broader laydown cleanup,
- the wood varnish project keeps expanding into wider compatibility or handling questions, or
- the team wants one surface additive route that can bridge several coating conversations beyond the first varnish drawdown.
This is the stronger first path when the real job is what happens after the film forms, not only how the film first looks.
How buyers should choose before the first sample round
1. Mulailah dengan hambatan sebenarnya
If the first commercial pressure is touch or feel in a non-waterborne route, start with 3370. If the visible film still needs better laydown, smoother appearance, or anti-blocking balance, start with 3432. If the appearance is already directionally acceptable but anti-sticking handling still is weak, move 3501 up first.
2. Keep feel logic separate from laydown logic
Wood varnish teams often collapse feel, gloss, and surface defects into one additive question. That usually slows down the lab. A feel-first route and a leveling-first route should not be treated as the same experiment.
3. Keep laydown logic separate from handling logic
Another common mistake is to keep tuning leveling when the real problem has already shifted into anti-sticking or downstream surface contact. 3432 is stronger when the film still needs smoother laydown. 3501 is stronger when the film already looks acceptable and the problem has shifted into handling.
4. Respect the system boundary
3370 excludes water-based use. 3432 and 3501 stay open across broader coating-system windows. That boundary matters because a nice-looking first trial can still become the wrong commercial route if it starts in the wrong system family.
5. Keep the first round small and honest
For many labs, the cleanest first sample plan is one 3370 feel-focused route, satu 3432 leveling-and-slip route, dan satu 3501 anti-sticking route. That usually teaches more than trying to force several adjacent silicone additives into the same starting lane.

PERTANYAAN YANG SERING DIAJUKAN
Which additive should I screen first for a solvent wood varnish where feel matters most?
Usually CHLUMIFE® 3370, because Longchang directly supports it for solvent and UV systems while excluding water-based use, making it a cleaner non-waterborne feel-first route.
When should 3432 move ahead of 3370?
3432 should move ahead when the film already reaches the surface but still needs better leveling, smoothness, slip, anti-blocking balance, or anti-cratering control.
When does 3501 make more sense than the other two?
3501 makes more sense when the varnish already looks directionally acceptable and the buyer’s real bottleneck has shifted into anti-sticking behavior or downstream handling stability.
Is this page replacing the waterborne wood coating page?
No. The waterborne page still answers a different buyer question first. This page is narrower and helps the buyer choose between three wood-varnish additive routes that are not the same job.
Need a tighter shortlist?
If your wood varnish project is stuck between surface feel, laydown quality, Dan anti-sticking handling, stop treating them as the same first additive request. Start with the real bottleneck. That usually makes the next CHLUMICRYL® sample decision faster and more commercially useful.
