This is the route to screen first when the formulation team does not want to split the initial work immediately into separate carbon-black, inorganic, and filler routes.<\/p>\n<p>Longchang\u2019s current page gives DP-D2645R the widest supported pigment scope here:<\/p>\n<ul>\n<li><strong>karbon siyah\u0131<\/strong><\/li>\n<li><strong>organik pigmentler<\/strong><\/li>\n<li><strong>inorganik pigmentler<\/strong><\/li>\n<li><strong>pigment and filler mixed dispersing<\/strong><\/li>\n<\/ul>\n<p>That matters because many waterborne industrial and architectural formulations are not simple single-pigment systems. They may combine extenders, fillers, white pigments, tinting pigments, and sometimes black components in one practical screen. If the team wants one first route that can stay open across that broader burden, DP-D2645R is usually the cleaner first benchmark.<\/p>\n<p>The current company-supported page also strengthens that position with a broader performance package: <strong>excellent gloss<\/strong>, <strong>color intensity<\/strong>, <strong>transparency<\/strong>, <strong>hiding power<\/strong>, <strong>no floating color or flooding<\/strong>, ve <strong>good storage stability<\/strong>.<\/p>\n<p>DP-D2645R deserves earlier review when:<\/p>\n<ul>\n<li>the waterborne program includes <strong>mixed pigment families<\/strong>,<\/li>\n<li>the screen also has to consider <strong>filler co-dispersion<\/strong>,<\/li>\n<li>the buyer wants to keep <strong>carbon black still in scope<\/strong>, veya<\/li>\n<li>the first lab round needs a <strong>broader commercial benchmark<\/strong> before narrowing into a more specialized route.<\/li>\n<\/ul>\n<p>The practical tradeoff is also clear. If the team already knows the project is a <strong>non-carbon-black TiO2 and filler route<\/strong> veya bir <strong>carbon-black-and-organic route<\/strong>, a tighter specialist product can sometimes teach faster than the broadest option.<\/p>\n<h2>When DP-D2791 is the better first move<\/h2>\n<p><strong>DP-D2791<\/strong> belongs earlier when the buyer wants a <strong>waterborne pigment route centered on titanium dioxide, inorganic pigments, fillers, and general organic pigments<\/strong>, but does not need carbon black in the same first-screen path.<\/p>\n<p>This is the cleanest separation point on the current product page. Longchang explicitly supports DP-D2791 for <strong>organic pigments, inorganic pigments, titanium dioxide, and fillers<\/strong>, and also states that it is <strong>not suitable for carbon black<\/strong>. That kind of direct exclusion is commercially useful because it stops the first sample round from becoming muddy.<\/p>\n<p>DP-D2791 should move up first when:<\/p>\n<ul>\n<li>the project is mainly about <strong>TiO2, filler, or inorganic-pigment stabilization<\/strong>,<\/li>\n<li>the buyer still wants an <strong>organic-pigment-capable waterborne route<\/strong>,<\/li>\n<li><strong>carbon black is not part of the first real package<\/strong>, veya<\/li>\n<li>the lab wants a route that stays cleaner for <strong>white, extender, and general color systems<\/strong> instead of forcing one universal answer.<\/li>\n<\/ul>\n<p>The company-supported benefits also stay commercially relevant: <strong>excellent gloss<\/strong>, <strong>color intensity<\/strong>, <strong>transparency<\/strong>, <strong>covering power<\/strong>, ve <strong>good storage stability<\/strong>.<\/p>\n<p>The limitation should remain visible. If the project really is moving toward <strong>karbon siyah\u0131<\/strong>, this is not the page\u2019s best first route. Longchang says that clearly, so the buyer should use that boundary instead of treating DP-D2791 as a catch-all waterborne dispersant.<\/p>\n<h2>When DP-D2792 is the better first move<\/h2>\n<p><strong>DP-D2792<\/strong> becomes more attractive when the formulation is already behaving like a <strong>carbon-black or all-organic-pigment job<\/strong> rather than a broad mixed-pigment or TiO2-and-filler job. This is the tighter specialist route on the page when black and strong color work drive the first decision.<\/p>\n<p>Longchang supports DP-D2792 for grinding <strong>carbon black and all organic pigments<\/strong>. The same page also supports <strong>excellent gloss<\/strong>, <strong>color intensity<\/strong>, <strong>transparency<\/strong>, <strong>covering power<\/strong>, <strong>no floating color or flooding<\/strong>, ve <strong>good storage stability<\/strong>.<\/p>\n<p>That pushes DP-D2792 earlier when:<\/p>\n<ul>\n<li>the buyer is screening a <strong>carbon-black-heavy waterborne system<\/strong>,<\/li>\n<li>the package is dominated by <strong>all-organic-pigment color work<\/strong>,<\/li>\n<li>the team wants a route that stays tighter around <strong>black and color concentrate logic<\/strong>, veya<\/li>\n<li>the first round should avoid carrying unnecessary TiO2-and-filler assumptions.<\/li>\n<\/ul>\n<p>Its visible dosage logic also fits that specialization, with <strong>10% to 50%<\/strong> for organic pigments and <strong>30% to 100%<\/strong> for carbon black. That is a clearer starting route when carbon-black demand is real, not hypothetical.<\/p>\n<p>The tradeoff is straightforward. If the formulation burden is really <strong>broader than carbon black and organic pigments<\/strong>, or if the screen is more about <strong>TiO2 and fillers<\/strong>, another route on this page usually belongs first.<\/p>\n<h2>Al\u0131c\u0131lar numune talep etmeden \u00f6nce nas\u0131l se\u00e7im yapmal\u0131d\u0131r?<\/h2>\n<h3>1. Start with the real pigment package, not the broadest product name<\/h3>\n<p>If the package includes carbon black, organic pigments, inorganic pigments, and fillers together, DP-D2645R usually deserves the first look. If the project is mainly TiO2, fillers, and inorganic pigments without carbon black, DP-D2791 becomes cleaner. If the work is carbon-black or organic-pigment-led, DP-D2792 usually moves up.<\/p>\n<h3>2. Use the carbon-black boundary honestly<\/h3>\n<p>DP-D2791 is not suitable for carbon black on the current Longchang page. That is not a minor note. It is a buyer-shortlist boundary and should be treated that way from the start.<\/p>\n<h3>3. Keep storage stability in the first screen<\/h3>\n<p>All three pages carry storage-stability language. That means buyers should not judge the first round only by fresh grind appearance. If the formulation must sit in inventory or travel through real supply conditions, storage behavior belongs in the same early decision.<\/p>\n<h3>4. Do not confuse broad scope with best fit<\/h3>\n<p>DP-D2645R has the broadest supported scope on this page, but that does not automatically make it the best first route for every waterborne project. A tighter specialist route often teaches faster when the pigment burden is already obvious.<\/p>\n<h3>5.
