Schnelle Antwort: Käufer vergleichen CHLUMICRYL® DP-D200R, CHLUMICRYL® DP-D262Rund CHLUMICRYL® DP-D265R usually get to a better first shortlist when they stop asking for a generic solvent-based dispersant and instead separate three different first-screen jobs. DP-D200R should move up first when the project needs strong viscosity reduction, organic-bentonite slurry preparation, and a route already recommended for architectural, industrial, or anti-corrosion coatings. DP-D262R belongs earlier when the buyer works in a solvent-based two-component or thermosetting system and needs very good carbon-black color spreading and gloss, but should keep its stated exclusions for thermoplastic acrylic und epoxy floor coating systems visible. DP-D265R deserves earlier review when the line is closer to solvent-based coatings or inks that need high color spreading for organic pigments, excellent blackness for high-pigment carbon black, and explicit fit for a thermoplastic acrylic resin system.
That is the commercially useful split. This page is for buyers who are already inside the CHLUMICRYL dispersant branch and need a narrower answer than a broad dispersants-for-coatings-and-inks guide.
Warum dieser Vergleich eine eigene Seite verdient
Longchang hat bereits eine breitere Seite über Wie man Dispergiermittel für pigmentierte Beschichtungen und Tinten auswählt plus a live narrower comparison at DP-D241R vs DP-D2641R vs DP-D265R. Those pages help buyers decide whether the problem belongs in the dispersant lane and how to think about primer-side viscosity reduction, matte-powder handling, or storage-stable high-pigment grinding.
This page answers a different buying question: which CHLUMICRYL dispersant should be screened first when the choice is really between organic-bentonite slurry efficiency, carbon-black gloss in 2K or thermoset solvent systems, and thermoplastic-acrylic-friendly pigment dispersion?
That narrower question is worth its own B2B page because these three products do not solve the same first problem, even though they all sit in solvent-side pigment-dispersion work.
What buyers are usually trying to fix before they ask for this shortlist
In practical coatings and inks work, this comparison usually appears after a team realizes that “we need a dispersant” is still too broad. The real first-screen issue is often one of these:
- the grind is carrying too much viscosity and needs a cleaner route for organic bentonite slurries or broader industrial-coating flow
- the system is a two-component or thermosetting solvent-based coating where carbon-black color development and gloss matter more than a generic all-purpose dispersant label
- the formulation is in a thermoplastic acrylic resin system and the buyer needs a route that explicitly stays inside that boundary
- the lab is balancing color strength, blacknessund viscosity reduction rather than screening by one benefit word alone
That also matches the general industry pattern around dispersant selection, where buyers commonly narrow by pigment type, resin-system compatibilityund grind-viscosity behavior instead of choosing only by brand or solids level.

When DP-D200R is the better first screen
DP-D200R should move to the front when the buyer is not only chasing pigment wetting, but needs a route that is already supported around ausgezeichnete Dispersionseffizienz, viscosity reduction, Hochglanz, enhanced color intensity, and increased transparency and hiding power In Lösungsmittelbasierte Systeme. The current Longchang page also gives one especially useful clue: it says DP-D200R is very suitable for the preparation of organic bentonite slurries und ist especially recommended for architectural coatings, industrial coatings, and anti-corrosion coating systems.
That makes DP-D200R the cleaner first route when:
- the dispersant has to help an organic-bentonite slurry path rather than only a narrow carbon-black route
- the coating team cares about viscosity reduction as much as color development
- Das Projekt liegt näher an architectural, industrial, oder anti-corrosion solvent-based coating logic
- the buyer wants a route that supports both appearance and grind-handling improvement
Longchang’s current usage note is also practical: the dispersant should be added to the grinding material and stirred well before adding pigment. That keeps the page commercially grounded instead of sounding like another abstract product summary.
When DP-D262R is the better first screen
DP-D262R deserves earlier review when the buyer already knows the project is a solvent-based two-component or thermosetting system and wants a route supported around carbon-black color spreading and gloss. Longchang describes DP-D262R as a polymeric block copolymer solution with pigment affinity groups and states that dispersing carbon black gives very good color spreading and gloss. The current page also says it can be used in two-component and thermosetting systems.
That pushes DP-D262R ahead when:
- the real target is carbon-black development in a solvent-based industrial system
- the resin family is closer to 2K oder thermoset logic than thermoplastic acrylic
- the team wants the supported dosage structure for inorganic pigments, organic pigmentsund Ruß already visible during screening
- storage handling matters, but the buyer can work within a route that may stratify or turn turbid below 5°C and then recover after heating and mixing
The biggest watchpoint is also explicit on the company page: DP-D262R is not applicable to thermoplastic acrylic and epoxy floor coating systems. That limitation is not a footnote. It is one of the clearest reasons this product should not be treated as a universal solvent-side dispersant.
When DP-D265R is the better first screen
DP-D265R belongs earlier when the buyer still wants solvent-based dispersion, but the commercial question is more about organic-pigment color spreading, high-pigment carbon-black blackness, and a route that can be used in a thermoplastic acrylic resin system. Longchang supports DP-D265R for solvent-based coatings and inks and states that dispersing organic pigment has high color spreading, dispersing high-pigment carbon black has excellent blackness, and the product has an excellent viscosity reduction effect.
That makes DP-D265R the cleaner first route when:
- the application is in solvent-based coatings or inks, not just a generic industrial coating bucket
- the buyer needs a route that explicitly stays usable in thermoplastische Acrylharzsysteme
- the first shortlist is being driven by color strength, blackness, and viscosity reduction together
- the lab wants a supported dosage framework that is slightly tighter on organic pigments than the DP-D262R route
In short, DP-D265R becomes more defensible when the project is not asking for a thermoset-only carbon-black answer, but for a solvent-side route that is still comfortable in thermoplastic acrylic and ink-adjacent work.
Wie Käufer vor der Anforderung von Mustern auswählen sollten
1. Start with the resin-system boundary
If the system is clearly thermoplastic acrylic, DP-D265R deserves earlier attention because the current Longchang page explicitly allows it there. If the system is clearly two-component oder thermosetting, DP-D262R becomes more logical. If the project is more about organic-bentonite slurry preparation and broad industrial viscosity reduction, DP-D200R often makes more sense as the first benchmark.
2. Separate pigment-development goals from grind-handling goals
DP-D200R is easier to justify when the project cares about slurry preparation, viscosity reduction, transparency, and hiding power. DP-D262R is cleaner when carbon-black gloss in 2K or thermoset systems matters most. DP-D265R should move up when organic-pigment color strength and thermoplastic-acrylic compatibility are central.
3. Do not ignore the exclusions
One of the easiest ways to waste a sample round is to overlook the current company-page boundary that DP-D262R is not applicable to thermoplastic acrylic or epoxy floor coating systems. That exclusion should shape the shortlist early.
4. Keep dosage logic practical
DP-D262R and DP-D265R both provide pigment-class dosage bands. Those bands should guide the first grind plan rather than encouraging a blind one-dose screen across all pigment families.
5. Treat the first sample round as a decision round, not a popularity test
For many buyers, the cleanest lab plan is one route centered on organic-bentonite and broad viscosity reduction, one route centered on 2K or thermoset carbon-black gloss, and one route centered on thermoplastic-acrylic color development. That usually teaches more than screening several near-neighbor dispersants without a clear hypothesis.

FAQ
Which product is the best first screen for organic bentonite slurry preparation?
Usually DP-D200R, because the current Longchang page explicitly says it is very suitable for the preparation of organic bentonite slurries and also supports viscosity reduction, gloss, and color-intensity improvement in solvent-based systems.
When should buyers start with DP-D262R instead of DP-D265R?
Start with DP-D262R earlier when the project is clearly in a solvent-based two-component or thermosetting system and the main target is carbon-black color spreading and gloss. Start with DP-D265R earlier when the system needs thermoplastic-acrylic compatibility or stronger organic-pigment color-development logic.
Can DP-D262R be used in thermoplastic acrylic systems?
No. The current Longchang product page explicitly says DP-D262R is not applicable to thermoplastic acrylic and epoxy floor coating systems.
Why is DP-D265R a cleaner route for some coatings and inks buyers?
Because the current company page directly supports its use in solvent-based coatings and inks and explicitly allows it in thermoplastic acrylic resin systems, while also framing it around organic-pigment color spreading, high-pigment carbon-black blackness, and viscosity reduction.
Does DP-D200R have the same dosage bands shown for DP-D262R and DP-D265R?
Not on the current product-page section used for this article. For this reason, buyers should treat DP-D200R’s supported strengths as slurry-preparation, viscosity-reduction, and industrial-coating guidance rather than assuming the same dosage structure shown on the other two pages.
Need a faster dispersant shortlist?
If your coating or ink team is losing time between organic-bentonite handling, 2K thermoset carbon-black glossund thermoplastic-acrylic pigment dispersion, do not screen these three products as if they solve the same first problem. Start by separating the resin-system boundary and the pigment-development target. That usually shows much faster whether DP-D200R, DP-D262R, or DP-D265R deserves the first sample round.
