빠른 답변: if the buyer is already down to 클로미크릴® DP-D242, DP-D2608R, 그리고 DP-D2609R, the right first screen depends on what kind of matte paste you are actually building. DP-D242 should move first when the paste is resin-free or the project still behaves like a real pigment-dispersion and multi-pigment stability problem. DP-D2608R belongs earlier when the main pressure is matte powder plus inorganic-filler stability together with viscosity reduction and lower gloss. DP-D2609R deserves the earlier screen when the route is a 고농축 무광 페이스트 built around matte powder, glass powder, or ultra-fine talc.
이 페이지는 더 넓은 페이지보다 폭이 좁습니다. matte-paste dispersant selection guide. That earlier page answers the application-level buyer question. This page answers the product-vs-product shortlist question once the lab already knows these three dispersants are the serious candidates.
이 비교를 위한 별도의 페이지가 필요한 이유
On a dense CHLUMICRYL® branch, a comparison page only deserves to exist if it solves a cleaner buyer question than the broader application guide. That is the case here. Buyers who search individual product codes are usually no longer asking, “Do I need a matte-paste dispersant at all?” They are asking, which of these three routes should I test first, and why?
General industry practice around matte pastes usually separates three different pressure points:
- paste architecture, especially whether the route must stay resin-free or low-binder,
- filler package behavior, especially whether matte powder must stay stable with inorganic fillers, and
- process concentration, especially whether the job is a higher-solids or high-concentration concentrate rather than a lighter grind.
The comparison below keeps that framing conservative and uses Longchang-supported product facts for the actual CHLUMICRYL® differentiation.
Quick comparison table: which route belongs first?
| 관찰된 구매자 우선순위 | 최적의 첫 번째 경로 | 왜 이것이 첫 번째에 있어야 하는가 | 주요 감시 지점 |
|---|---|---|---|
| Resin-free matting paste, pigment wetting still matters, or the project also worries about floating color and flowering | DP-D242 | Longchang supports resin-free matting-paste fit, pigment wetting and dispersion, viscosity reduction for organic bentonite and matting powder, and reduced floating color and flowering in multi-pigment systems | Best when the paste still behaves like a real pigment-dispersion problem, not only a filler-alignment problem |
| Matte powder must stay stable with inorganic fillers, and the lab wants one route with broader filler compatibility | DP-D2608R | Longchang supports excellent viscosity reduction for matte powder and inorganic filler, improved dispersion and stability, directional alignment, and broad compatibility with most matte powder and inorganic fillers | This is the cleaner first route when the job is filler-package control more than resin-free paste architecture |
| High-concentration matte paste based on matte powder, glass powder, or ultra-fine talc | DP-D2609R | Longchang directly supports high-concentration matte-paste production plus excellent viscosity reduction and directional alignment for gloss reduction | If used in 2K PU systems, Longchang says service life and drying speed should be evaluated |
What Longchang directly supports for each product
DP-D242, resin-free matting paste and multi-pigment control
롱창 포지션 DP-D242 ~로서 polymer block copolymer with pigment affinity groups ~을 위한 solvent-based and UV-curable systems. The supported page highlights several points that matter for this comparison:
- 안료의 우수한 습윤성 및 분산성,
- 유기 안료 분산 시 착색 강도 향상,
- good viscosity reduction for organic bentonite and matting powder,
- special suitability for resin-free matting paste, 그리고
- reduced 떠다니는 색깔과 꽃 다중 색소 시스템에서.
Its supported use method is also useful for buyers comparing lab workflow: add the dispersant to the grinding material first, stir well, then add pigment for grinding and dispersion.
DP-D2608R, matte powder plus inorganic-filler stability
롱창 포지션 DP-D2608R as an acrylate copolymer solution ~을 위한 solvent-based and UV-curable systems. The product page separates it clearly from DP-D242 in several commercially useful ways:
- excellent viscosity reduction for matte powder and inorganic filler,
- 무광 분말 및 충전제의 분산성 및 안정성 향상
- good directional alignment effect on matte powder and effective gloss reduction,
- compatibility with most matte powder and other inorganic fillers because of its alkaline pigment-affinity group, and
- recommended dosage of 3% to 15% for matte powder, based on additive supply.
The supported use method is to mix resin, solvent, and dispersant well first, then add color filler or matte powder and disperse at high speed.
DP-D2609R, high-concentration matte-paste processing
롱창 포지션 DP-D2609R ~로서 polymer solution containing pigment anchoring groups ~을 위한 solvent-based and UV-curing systems. The supported product page makes its role more specific than the other two:
- excellent viscosity reduction for matte powder, glass powder, and ultra-fine talc,
- direct use in the production of 고농축 무광 페이스트,
- good directional alignment effect on matte powder and effective gloss reduction, and
- recommended dosage of 2% to 20% for matting powder, based on additive supply.
The main supported watchpoint is important and should not be hidden. Longchang explicitly says that if DP-D2609R is used in a 2K PU system, the effect on service life and drying speed needs evaluation.
DP-D242가 더 나은 첫 수일 때
DP-D242 belongs first when the matte paste is not only a gloss-control project. It is the stronger first route when the job still has a pigment-dispersion character, especially if the paste is resin-free or the buyer is also trying to reduce the risk of 떠다니는 색깔과 꽃 later in a multi-pigment system.
That is what makes it distinct from the other two routes. DP-D2608R and DP-D2609R are both strong when the buyer is already deep into matte-powder and filler architecture. DP-D242 deserves to move ahead when the project still needs help at the intersection of pigment wetting, matting-paste viscosity control, 그리고 appearance stability.
- 첫 화면 사용에 가장 적합한 방법: resin-free matting paste or matte paste with a real multi-pigment stability concern
- 시스템 호환성: solvent-based and UV-curable systems
- Why buyers choose it: resin-free fit plus floating-color and flowering control support
- 실용적인 참고 사항: start by adding it to the grinding material before pigment addition
DP-D2608R이 더 나은 첫 번째 선택일 때
DP-D2608R belongs earlier when the matte paste behaves more like a matte-powder-plus-inorganic-filler compatibility job. It is the cleaner route when the buyer wants one product that directly addresses both 점도 감소 및 stability across a wider filler package.
That difference matters. Some matte-paste projects are not primarily about resin-free architecture or multi-pigment appearance control. They are about making sure the matte powder and inorganic filler package can disperse cleanly, stay stable, align well enough to reduce gloss, and fit more than one filler type without excessive reformulation. That is the commercial logic that pushes DP-D2608R forward.
- 첫 화면 사용에 가장 적합한 방법: matte powder together with inorganic fillers
- 시스템 호환성: solvent-based and UV-curable systems
- Why buyers choose it: broader filler compatibility and a direct stability signal
- 복용량 안내: 3% to 15% for matte powder, based on additive supply
DP-D2609R이 더 나은 첫 번째 수일 때
DP-D2609R should move to the front when the buyer is building a 고농축 무광 페이스트 rather than only a conventional matte grind. Longchang’s own page makes this the clearest direct signal by stating that the product can be used in the production of 고농축 무광 페이스트.
This route also becomes more attractive when the filler package includes glass powder 또는 ultra-fine talc, not only matte powder. That gives it a narrower but very useful first-screen role. It is the stronger benchmark when the lab’s real challenge is higher-concentration process behavior plus viscosity reduction, not only broad filler compatibility.
- 첫 화면 사용에 가장 적합한 방법: high-concentration matte paste, especially with glass powder or ultra-fine talc
- 시스템 호환성: solvent-based and UV-curing systems

구매자가 샘플을 요청하기 전에 선택해야 할 사항
1. Start with the real architecture of the paste
If the project must stay resin-free or low-binder, DP-D242 deserves an earlier look. If the core challenge is filler compatibility and matte-powder stability, DP-D2608R is usually the cleaner first route. If the concentrate is moving into a high-concentration window, DP-D2609R should move up.
2. Separate pigment problems from filler problems
DP-D242 carries the strongest supported signal for pigment wetting, organic-pigment coloring strength, and reduced floating color and flowering. The other two routes are more clearly anchored in matte powder and filler architecture.
3. Use the watchpoint, not only the headline benefit
DP-D2609R may look attractive for concentration and gloss reduction, but Longchang’s 2K PU caution matters. If the project is inside a 2K PU window, that evaluation burden is part of the selection decision, not an afterthought.
4. Keep the first panel tight
Most matte-paste buyers learn more from a disciplined first panel with one resin-free or multi-pigment route, 하나 filler-stability route그리고 하나 high-concentration route than from a crowded panel of similar dispersants.

자주 묻는 질문
Which dispersant is the better first screen for a resin-free matte paste?
DP-D242 is the better first screen when the matte paste must stay resin-free and the project also needs pigment wetting plus better control of floating color and flowering in multi-pigment systems.
When is DP-D2608R a better first route than DP-D242?
DP-D2608R is usually the better first route when the project behaves more like a matte-powder and inorganic-filler stability problem than a resin-free or multi-pigment pigment-dispersion problem.
Why would a buyer start with DP-D2609R?
Start with DP-D2609R when the job is a high-concentration matte paste, especially if the filler package includes matte powder, glass powder, or ultra-fine talc and the team needs stronger viscosity reduction plus gloss reduction through directional alignment.
What is the key caution for DP-D2609R?
Longchang says that if DP-D2609R is used in 2K PU systems, the effect on service life and drying speed needs to be evaluated.
Need a faster matte-paste shortlist?
If your lab is already choosing between DP-D242, DP-D2608R, 그리고 DP-D2609R, do not treat them as interchangeable. First decide whether the real job is resin-free paste control, broader filler stability, 또는 high-concentration matte-paste processing. That usually leads to the right CHLUMICRYL® route much faster than comparing viscosity reduction claims alone.
