빠른 답변: wetting additives should be chosen when the main problem is how the coating or ink spreads on the substrate, not when the core issue is pigment stability or final-surface leveling. If the system pulls back on film, struggles on plastic or metal, shows poor edge coverage, or has trouble wetting low-surface-energy surfaces, the first shortlist should usually start with a CHLUMICRYL® wetting-agent route.
This matters because substrate coverage problems are often mistaken for general formulation weakness. In practice, many coating and ink systems fail not because the resin is wrong, but because the liquid does not spread, anchor, or cover the surface in a stable way.
What wetting additives solve in coatings and inks
Wetting additives are most useful when the dominant formulation pressure is substrate behavior. Common buyer-side warning signs include:
- Poor spreading: the coating or ink beads up instead of forming a clean film.
- Edge pullback: the material retreats from corners, borders, or fine print zones.
- Difficult film or plastic surfaces: low-surface-energy substrates resist uniform coverage.
- Uneven decorative appearance: the system does not lay down consistently on metal, plastic, or coated stock.
- Process instability: print and coating results shift too much when surface tension changes across batches.
If one of those is the main problem, wetting additives belong early in the screen.
When to choose wetting additives before other additive types
| 관찰된 문제 | 최적의 첫 번째 첨가 방향 | 왜 |
|---|---|---|
| Poor spreading on plastic, film, or metal | 습윤 첨가제 | The bottleneck is substrate coverage, not pigment or gloss control |
| Edge pullback or uneven border coverage | 습윤 첨가제 | Coverage behavior needs to be corrected before broader surface tuning |
| Weak pigment stability or color drift | 분산제 | The issue is pigment management rather than substrate wetting |
| Poor flow or gloss uniformity after good coverage | 수평 조절 첨가제 | The main issue is surface laydown, not spreading |
| Extreme repellency or special defect control needs | 불소 계면활성제 | A more specialized surface-control route may be required |

CHLUMICRYL® wetting routes to review first
The current CHLUMICRYL® wetting branch already includes routes such as 클로미크릴® WD-D545, CHLUMICRYL® WD-D547, 그리고 CHLUMICRYL® WD-D548. Longchang currently positions these as organosilicon wetting agents for water-based, solvent-based, and coating wetting systems, which makes them relevant as first-review routes for broad substrate-coverage work.
클로미크릴® WD-D545
- 롱창이 지원하는 것: organosilicon wetting agent for water-based, solvent-based, and coating wetting systems
- 왜 초반에 배우는 것이 좋은가: it fits broad wetting screens where the buyer needs a stable general route across multiple formulation environments
CHLUMICRYL® WD-D547
- 롱창이 지원하는 것: organosilicon wetting agent for water-based, solvent-based, and coating wetting systems
- 왜 초반에 배우는 것이 좋은가: it gives a second wetting route when the buyer needs to compare substrate response or process stability instead of relying on a single option
CHLUMICRYL® WD-D548
- 롱창이 지원하는 것: organosilicon wetting agent for water-based, solvent-based, and coating wetting systems
- 왜 초반에 배우는 것이 좋은가: it helps establish another practical route for buyers screening different substrate and line conditions within the same broad wetting family
How buyers should screen wetting additives
1. Define the substrate before choosing the additive
Plastic films, coated paper, metal, and decorative stock do not behave the same way. The substrate should define the first shortlist.
2. Separate spreading issues from pigment issues
If the liquid does not cover the surface properly, wetting belongs earlier than dispersant or leveling changes.
3. Check edge and fine-feature behavior
It is not enough for the center of a drawdown to look acceptable. Edge coverage and difficult geometry often reveal the real wetting problem.
4. Keep the formulation family in scope
Water-based, solvent-based, and coating wetting systems can all use wetting additives, but the right route still depends on the process and substrate combination.
5. Use a short first comparison
The cleanest first step is usually to compare the most relevant CHLUMICRYL® wetting routes rather than mixing multiple additive families too early.

자주 묻는 질문
What is the main reason to use a wetting additive?
The main reason is to improve how the coating or ink spreads and covers the substrate, especially on more difficult or lower-energy surfaces.
Should I start with a wetting additive or a leveling additive?
Start with a wetting additive when the problem is spreading or substrate coverage. Start with a leveling additive when coverage is already acceptable but the final surface still looks poor.
Can wetting additives help both coatings and inks?
Yes. The current CHLUMICRYL® wetting routes are already positioned across water-based, solvent-based, and coating wetting systems, which makes them relevant across multiple formulation families.
Why compare WD-D545, WD-D547, and WD-D548?
Because they are already grouped by Longchang inside the same wetting-additive branch, making them a clean first shortlist for substrate-coverage screening.
Need help narrowing the wetting shortlist?
If your coating or ink project is being limited by poor spreading, edge pullback, or difficult substrate coverage, start with the wetting problem itself and shortlist the most relevant CHLUMICRYL® wetting route first. That usually gives a faster and cleaner screening path than treating all additive families as interchangeable.
