快速回答： 买家正在 plastic coatings usually get to a better first shortlist when they stop asking for one additive to solve everything and instead separate three different jobs. CHLUMIWE® 3071 should move first when the immediate problem is low-surface-energy wetting, poor spread, or weak first contact on plastic substrates. CHLUMILE® 3345 deserves the earlier screen when the coating already wets better but still needs a broader wetting-and-leveling balance to lay down more evenly. CHLUMIFE® 1206 belongs earlier when the main commercial target is post-cure abrasion resistance, 不粘, or smoother surface handling in a solvent-side or UV route.
That is the commercially useful split. Plastic-coating projects often fail because the team mixes together 基材润湿, film laydown， 和 cured-film handling as if they were the same additive decision.
Why plastic coatings deserve their own additive page
龙昌已经有了上线页面 润湿添加剂, 找平添加剂, 润滑剂, and the broader CHLUMICRYL® 涂层和油墨添加剂 hub. Those pages help buyers decide which additive family belongs in the discussion.
This page answers the narrower B2B application question that comes next: which route should plastic-coating buyers screen first when the issue is low-surface-energy wetting, smoother film formation after wetting, or post-cure abrasion and sticking control?
That is a distinct page type. It is an application page, not just another broad function page.
What makes plastic coatings different from an ordinary coating screen
In conservative general-industry terms, plastic parts are often harder to wet because many plastics present a lower surface energy than metal or mineral surfaces. When the coating cannot make fast, clean contact with that surface, buyers often see beading, pullback, edge retreat, or an uneven film. That still does not mean every plastic-coating issue is only a wetting issue.
In practice, the first bottleneck usually lands in one of these lanes:
- the coating is not wetting the plastic surface cleanly enough
- the coating wets better after a surfactant push but still does not level the way the buyer wants
- the coating lays down acceptably, but the cured film still needs better abrasion or anti-sticking handling
That is why a plastic-coating page deserves a separate shortlist instead of repeating the general wetting page.
Quick comparison table: which route solves what first?
| Buyer priority in plastic coatings | 最佳首选路线 | 为什么它应该排在第一位 | 主要观察点 |
|---|---|---|---|
| Low-surface-energy wetting, poor substrate contact, or slow spread on plastic parts | CHLUMIWE® 3071 | Longchang positions it as an organosilicone wetting agent with broad system fit, low surface tension, flexible addition timing, and explicit waterborne / solvent / UV applicability | In water-based systems it may stabilize foam, so wetting gains should be checked together with bubble risk |
| The coating wets but still needs smoother, more even laydown on plastic surfaces | CHLUMILE® 3345 | Longchang positions it directly as a wetting-and-leveling route with the same broad system window plus the note that co-solvents can enhance the effect | Buyers still need to confirm whether the job is really film laydown balance instead of a deeper adhesion or foam problem |
| The film already forms, but the cured surface still needs better abrasion, anti-sticking, or handling behavior | CHLUMIFE® 1206 | Longchang positions it in the hand-feel / abrasion-resistance lane and connects it to solvent-side or UV surface-control work where cured-film slip and anti-sticking behavior matter more | Use should stay disciplined around the supported system window and late-stage addition logic rather than treating it as the first answer to pure wetting failure |
When CHLUMIWE® 3071 is the better first move
3071 should move to the front when the project is clearly failing at the surface-contact step龙昌支持它作为 polyether-modified polysiloxane wetting agent with recommended dosage at 0.1% 至 1.0% of the total formulation. The company page allows addition during grinding, stirring, or after production, supports dilution with water, alcohols, alkanes, and aromatics, and places it across 紫外线, 溶剂， 和 水基系统.
That makes 3071 the cleaner first screen when:
- plastic parts or coated plastic panels are showing poor spread or weak first contact
- the buyer needs a clear wetting-first benchmark before changing broader surface packages
- the project may still move between water-based, solvent, and UV routes during development
The important watchpoint is also company-supported: in 水基系统 3071 may stabilize foam. That means better wetting alone is not enough to judge whether it is the right commercial route.
When CHLUMILE® 3345 is the better first move
3345 deserves earlier review when the buyer is not only trying to wet the plastic surface. It is the stronger first route when the coating must also lay down more evenly after it wets. Longchang positions 3345 directly as a wetting and leveling agent, supports the same 0.1% 至 1.0% dosage range, the same broad 紫外、溶剂和水基 applicability, and the same flexible addition timing during grinding, stirring, or after production.
The product page also adds a useful practical note: co-solvents such as dipropylene glycol methyl ether can enhance the effect. That gives 3345 a clear role when the plastic-coating issue is no longer only surface contact, but how the film finally relaxes and levels.
3345 should move earlier when:
- the coating already wets better after surfactant adjustment, but still looks uneven
- the team wants a balanced wetting-plus-leveling route instead of a pure wetting push
- the project needs a broad system window while still staying inside a more appearance-led screen
When CHLUMIFE® 1206 is the better first move
1206 should move ahead when the project is no longer being blocked mainly by wetting or flow-out. It belongs earlier when the buyer is already closer to an acceptable film and needs stronger post-cure surface handling. Longchang positions 1206 in the hand-feel / abrasion-resistance / non-reactive additive lane and supports it with a dosage window of 0.1% 至 1.0%. The company page also supports late-stage addition with the option of pre-dilution in suitable solvent, and it places the product in a route that is especially relevant to solvent-side gravure or flexographic inks plus broader coating surface-control work.
That makes 1206 useful on a plastic-coating page when the real question is not whether the film will wet the part, but whether the final surface still needs better:
- 耐磨性
- anti-sticking or release-oriented handling
- surface feel and movement in a solvent-side or UV finishing route
In short, 1206 should not be the first answer to crawling or pullback. It should move earlier when the plastic coating already forms and the finished-surface handling target is becoming the bigger commercial issue.
买家在索取样品前应该如何选择
1. Start with the first visible failure
If the coating cannot wet the plastic surface cleanly, start with 3071. If it wets but still lays down unevenly, move 3345 earlier. If the film is already forming acceptably and the bigger issue is abrasion or sticking, 1206 becomes more logical.
2. Do not mix pre-application and post-cure jobs
Wetting and leveling routes work at the point of film formation. Abrasion-resistance and anti-sticking routes matter more after the film has already formed. Buyers save time when they keep those stages separate.
3. Keep the system window visible
3071 and 3345 both carry broad UV, solvent, and water-based applicability on the current company pages. 1206 belongs earlier when the development path is closer to the solvent-side or UV surface-control lane rather than a purely water-based wetting question.
4. Use the watchpoint, not only the headline benefit
3071 may stabilize foam in water-based systems. 3345 may need co-solvent support for the best effect. 1206 works best when the team already knows the job is post-cure surface handling rather than basic substrate wetting. Those practical notes often decide the better first route.
5. Keep the first round tight
For many plastic-coating buyers, one wetting-first route， 一 wetting-plus-leveling route，以及一个 post-cure abrasion route teach more than a crowded first panel with too many overlapping additives.

常见问题
Which additive should I screen first if a plastic coating beads or pulls back?
Usually CHLUMIWE® 3071, because the first problem is often low-surface-energy wetting rather than final abrasion or slip.
When is 3345 a better first route than 3071?
3345 is the cleaner first route when the coating already wets better but still needs a smoother, more even film after application.
When should 1206 move ahead of wetting or leveling additives?
1206 should move ahead when the film already forms acceptably and the bigger issue is post-cure abrasion resistance, anti-sticking behavior, or finished-surface handling.
Can 1206 replace a true wetting additive on plastic substrates?
No. 1206 is not the first answer to low-surface-energy wetting failure. It belongs later in the shortlist when the buyer is working on finished-surface behavior rather than initial substrate contact.
Need a faster shortlist for plastic coatings?
If your team is stuck between wetting plastic surfaces, leveling the film after wetting， 和 improving the cured surface, define which stage is actually failing first. That usually shows much faster whether CHLUMIWE® 3071, CHLUMILE® 3345, or CHLUMIFE® 1206 deserves the first sample round.
