Start with <a href=\"https:\/\/longchangchemical.com\/nl\/product\/chlumiwe-100\/\"><strong>CHLUMIWE\u00ae 2100<\/strong><\/a> when the waterborne flexo ink still needs stronger <strong>substraatbevochtiging<\/strong>, <strong>spread<\/strong>, and lower-surface-tension entry on film, coated paper, or another difficult surface. Move <a href=\"https:\/\/longchangchemical.com\/nl\/product\/chlumiag-3501\/\"><strong>CHLUMIAG\u00ae 3501<\/strong><\/a> forward when the ink already prints directionally but the <strong>dried print face still needs anti-sticking, release, or downstream handling control<\/strong>. Start with <a href=\"https:\/\/longchangchemical.com\/nl\/product\/chlumiaf-3062\/\"><strong>CHLUMIAF\u00ae 3062<\/strong><\/a> when the real bottleneck is <strong>foam, microbubbles, or recirculation-side air entrainment<\/strong> in a waterborne flexographic route.<\/p>\n<p>This page stays inside the redirected <strong>CHLUMICRYL\u00ae coating- en inktadditieven<\/strong> direction and does <strong>niet<\/strong> fall back to the older photoinitiator cluster. It also is not a duplicate of Longchang\u2019s already-live <a href=\"https:\/\/longchangchemical.com\/nl\/flexographic-ink-additives\/\">flexographic ink additives<\/a> page, which covers a broader chemistry window across UV, solvent, and water-based systems. The buyer question here is narrower: <strong>which additive deserves the first trial when the ink is specifically waterborne, printed by flexography, and still not giving a commercially stable result on the press line?<\/strong><\/p>\n<h2>Why waterborne flexographic inks deserve their own additive page<\/h2>\n<p>A <strong>waterborne flexographic ink<\/strong> sits in a tighter buyer lane than a broad flexographic article because the formulation has to keep together <strong>water-based process behavior<\/strong>, <strong>fast flexo transfer<\/strong>, En <strong>downstream handling after drying or rewinding<\/strong>. A lab drawdown may look acceptable while the live job still fails commercially because the ink does not wet the substrate cleanly, the printed face blocks or drags after drying, or the circulating system keeps pulling air into the ink.<\/p>\n<p>That makes waterborne flexo a cleaner application split than another generic ink page. Buyers often need to separate a <strong>surface-entry problem<\/strong>, A <strong>dried-face handling problem<\/strong>en een <strong>recirculation-side foam problem<\/strong> before they can judge the rest of the package honestly. Those are different first screens, even when one press trial shows all three symptoms together.<\/p>\n<p>General industry framing supports that split conservatively. Waterborne flexographic systems are commonly judged by how cleanly they wet films or coated stocks, whether the dried print face handles cleanly during rewinding, stacking, lamination, or later varnish steps, and whether foam or entrained air keeps disturbing transfer stability. The product-specific facts below still stay tied to current Longchang-supported product pages.<\/p>\n<h2>What the current company-supported evidence actually separates<\/h2>\n<ul>\n<li><strong>CHLUMIWE\u00ae 2100<\/strong> is supported by Longchang as a <strong>multi-component modified polydimethylsiloxane<\/strong> route with <strong>surface tension below 25 mN\/m<\/strong>, a recommended dosage of <strong>0,1% tot 1,0%<\/strong>, suitability for <strong>difficult-to-wet substrates<\/strong>, and applicability across <strong>UV<\/strong>, <strong>oplosmiddel<\/strong>, En <strong>op water gebaseerde systemen<\/strong>. Longchang also states that, with a small amount added, it will <strong>produceert geen stabiel schuim bij hoge dispersiesnelheden.<\/strong>.<\/li>\n<li><strong>CHLUMIAG\u00ae 3501<\/strong> is the broader <strong>print-face handling and anti-sticking route<\/strong>. Longchang lists it for <strong>drukinkten<\/strong>, <strong>inkjetinkten<\/strong>, <strong>zeefdrukinkten<\/strong>, <strong>overdrukvernis<\/strong>, <strong>lossingscoatings<\/strong>, En <strong>anti-sticking-agent use<\/strong>, while also supporting use across <strong>UV<\/strong>, <strong>oplosmiddel<\/strong>, En <strong>op water gebaseerde systemen<\/strong>. The current public page also says it can be added at <strong>any stage<\/strong> or later.<\/li>\n<li><strong>CHLUMIAF\u00ae 3062<\/strong> is supported by Longchang as a <strong>polyether-modified polysiloxane<\/strong> defoamer with a recommended dosage of <strong>0,1% tot 0,5%<\/strong> voor <strong>drukinkten<\/strong>, and applicability across <strong>UV<\/strong>, <strong>oplosmiddel<\/strong>, En <strong>op water gebaseerde systemen<\/strong>. The current public page directly positions it as a <strong>printing ink defoamer<\/strong>, which is a clean fit when the waterborne flexo line is being limited by foam or microbubble carry-through.<\/li>\n<\/ul>\n<p>That is enough company-supported separation to build a real B2B buyer page without inventing unsupported flexographic product facts. The goal is not to claim one additive solves every waterborne flexo complaint. The goal is to help the buyer choose the <strong>first better trial route<\/strong>.<\/p>\n<h2>Snelle vergelijkingstabel: welke route verdient de eerste plek op het scherm?<\/h2>\n<table>\n<thead>\n<tr>\n<th>Buyer priority in waterborne flexographic inks<\/th>\n<th>Beste eerste route<\/th>\n<th>Waarom het op de eerste plaats hoort<\/th>\n<th>Hoofdobservatiepunt<\/th>\n<\/tr>\n<\/thead>\n<tbody>\n<tr>\n<td>The waterborne flexo ink still hesitates, pulls back, or spreads weakly on film, coated stock, or another difficult substrate<\/td>\n<td><a href=\"https:\/\/longchangchemical.com\/nl\/product\/chlumiwe-100\/\">CHLUMIWE\u00ae 2100<\/a><\/td>\n<td>The supported route is built around very low surface tension, difficult-substrate wetting, and broad water-based applicability<\/td>\n<td>Use it when the first problem is still substrate entry, not when the real complaint starts after drying on the printed face<\/td>\n<\/tr>\n<tr>\n<td>The print already transfers directionally, but the dried face still blocks, drags, or handles poorly during rewinding or later contact<\/td>\n<td><a href=\"https:\/\/longchangchemical.com\/nl\/product\/chlumiag-3501\/\">CHLUMIAG\u00ae 3501<\/a><\/td>\n<td>Longchang directly supports it for printing-ink use, anti-sticking logic, and broader downstream handling across water-based systems<\/td>\n<td>Do not treat it as a substitute for true wetting correction when the ink still cannot enter the surface cleanly<\/td>\n<\/tr>\n<tr>\n<td>Foam, microbubbles, or air entrainment are still corrupting transfer stability or final print appearance<\/td>\n<td><a href=\"https:\/\/longchangchemical.com\/nl\/product\/chlumiaf-3062\/\">CHLUMIAF\u00ae 3062<\/a><\/td>\n<td>Longchang directly positions it as a printing-ink defoamer and supports water-based system use<\/td>\n<td>It is a defoaming route, not the first answer to a dried-face slip problem or a missing wetting route<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<h2>When CHLUMIWE\u00ae 2100 is the better first move<\/h2>\n<p><strong>2100<\/strong> should move first when the waterborne flexographic project still looks like a <strong>substrate-entry problem<\/strong>. This is the cleaner starting route when the ink is not spreading or covering the target surface cleanly enough to judge the rest of the package honestly.<\/p>\n<p>That distinction matters because waterborne flexo teams often see more than one complaint at once. A weakly wetting ink can also look rough, unstable, or bubble-prone simply because the film never settled correctly on the substrate in the first place. If the surface-entry route is still wrong, later handling or defoaming trials become harder to read.<\/p>\n<ul>\n<li><strong>Best first-screen use:<\/strong> difficult-substrate wetting and spread in waterborne flexographic inks<\/li>\n<li><strong>Supported dosage window:<\/strong> 0,1% tot 1,0% van de totale formulering<\/li>\n<li><strong>Belangrijkste sterkte:<\/strong> lower surface tension and cleaner substrate entry for difficult surfaces<\/li>\n<li><strong>Main caution:<\/strong> keep it as the first move when wetting is the dominant bottleneck, not when the print already lands acceptably and the real complaint starts later<\/li>\n<\/ul>\n<p>In short, 2100 is the better first move when the question is still <strong>how the waterborne flexo ink meets the substrate<\/strong>.<\/p>\n<h2>When CHLUMIAG\u00ae 3501 is the better first move<\/h2>\n<p><strong>3501<\/strong> should move ahead first when the ink already transfers directionally but still shows a <strong>dried-face handling problem<\/strong>. This route is stronger when the issue is not basic surface entry, but blocking, sticking, drag, release-oriented handling, or later contact pressure on the printed face.<\/p>\n<p>That matters in waterborne flexographic inks because many jobs are not finished when the ink simply lands on the web. Rewinding, stacking, lamination, overprint varnish, or later converting steps can expose a different additive problem from the original transfer stage. Longchang\u2019s current public page is useful here because 3501 is not positioned only as a narrow coating additive. The supported route keeps together <strong>drukinkten<\/strong>, <strong>overdrukvernis<\/strong>, <strong>lossingscoatings<\/strong>, En <strong>anti-sticking use<\/strong>, while staying open across <strong>UV<\/strong>, <strong>oplosmiddel<\/strong>, En <strong>op water gebaseerde systemen<\/strong>.<\/p>\n<ul>\n<li><strong>Best first-screen use:<\/strong> anti-sticking, release, and downstream handling control after the waterborne flexo ink already transfers directionally<\/li>\n<li><strong>Systeemgeschiktheid:<\/strong> UV, solvent, and water-based systems on the current public page<\/li>\n<li><strong>Belangrijkste sterkte:<\/strong> one route that already supports printing-ink use plus broader handling logic<\/li>\n<li><strong>Main caution:<\/strong> if the printed film still has obvious wetting failure, 3501 should not be used to hide a problem that still belongs to the 2100 route first<\/li>\n<\/ul>\n<p>So 3501 is the better first move when the waterborne flexographic project needs a <strong>handling-first cleanup route<\/strong> after transfer is already directionally acceptable.<\/p>\n<h2>When CHLUMIAF\u00ae 3062 is the better first move<\/h2>\n<p><strong>3062<\/strong> should move ahead first when the waterborne flexographic line is being limited by <strong>foam<\/strong>, <strong>microbubbles<\/strong>, of <strong>air entrainment<\/strong>. In those cases, a better wetting route or a better handling route usually will not give the team an honest print read until the foam pressure is under control.<\/p>\n<p>Longchang\u2019s public product page is direct here. 3062 is positioned as a <strong>printing ink defoamer<\/strong>, supports a <strong>0,1% tot 0,5%<\/strong> dosage window for printing inks, and remains open to <strong>op water gebaseerde systemen<\/strong>. That makes it commercially useful in waterborne flexography, where circulation, pumping, and press-side agitation can keep feeding air into the ink even after the drawdown itself looks acceptable.<\/p>\n<ul>\n<li><strong>Best first-screen use:<\/strong> persistent foam, microbubble carry-through, or waterborne air-release problems in flexographic inks<\/li>\n<li><strong>Supported dosage window:<\/strong> 0.1% to 0.5% of total formulation for printing inks<\/li>\n<li><strong>Belangrijkste sterkte:<\/strong> a defoaming route directly tied by Longchang to printing inks and water-based systems<\/li>\n<li><strong>Main caution:<\/strong> it is not a substitute for a true wetting route or a dried-face handling route when those are the real first bottlenecks<\/li>\n<\/ul>\n<p>This is the stronger first move when the visible defect is being limited by <strong>air management<\/strong>, not by missing wetting or missing handling control.<\/p>\n<h2>Hoe kopers een keuze moeten maken voordat ze monsters aanvragen.<\/h2>\n<h3>1. Start with the real first failure on the press line<\/h3>\n<p>If the waterborne flexo ink still hesitates on the substrate, start with 2100. If the ink already transfers directionally but still handles badly after drying, move 3501 forward. If foam or microbubbles are still corrupting the print read, start with 3062.<\/p>\n<h3>2. Keep substrate entry separate from dried-face handling<\/h3>\n<p>A waterborne flexographic ink that cannot wet the stock cleanly and a waterborne flexographic ink that prints acceptably but still blocks during rewinding are not the same additive problem. Separating those routes early usually makes the first trial set much more honest.<\/p>\n<h3>3. Keep foam control separate from both surface routes<\/h3>\n<p>Defoaming is not just a smaller version of wetting correction or anti-sticking control. If entrained air is still sitting in the system, it can distort how the team reads every later additive on the press.<\/p>\n<h3>4. Respect the watchpoint, not only the headline benefit<\/h3>\n<p>2100 brings a substrate-entry route. 3501 brings a broader anti-sticking and handling route. 3062 brings a direct printing-ink defoaming route. Those practical differences usually decide the better first route more than the additive family name alone.<\/p>\n<h3>5. Keep the first trial set small<\/h3>\n<p>For many waterborne flexographic buyers, one <strong>2100 wetting route<\/strong>, een <strong>3501 handling route<\/strong>en \u00e9\u00e9n <strong>3062 defoaming route<\/strong> teach more than an overloaded first screen filled with partially overlapping additives.<\/p>\n<h2>Aanbevolen route naar Longchange vanaf deze pagina<\/h2>\n<ul>\n<li><strong>Natte route:<\/strong> <a href=\"https:\/\/longchangchemical.com\/nl\/product\/chlumiwe-100\/\">CHLUMIWE\u00ae 2100<\/a><\/li>\n<li><strong>Handling route:<\/strong> <a href=\"https:\/\/longchangchemical.com\/nl\/product\/chlumiag-3501\/\">CHLUMIAG\u00ae 3501<\/a><\/li>\n<li><strong>Defoaming route:<\/strong> <a href=\"https:\/\/longchangchemical.com\/nl\/product\/chlumiaf-3062\/\">CHLUMIAF\u00ae 3062<\/a><\/li>\n<li><strong>Clusteroverzicht:<\/strong> <a href=\"https:\/\/longchangchemical.com\/nl\/chlumicryl-coating-ink-additives\/\">CHLUMICRYL\u00ae coating- en inktadditieven<\/a><\/li>\n<li><strong>Related broad page:<\/strong> <a href=\"https:\/\/longchangchemical.com\/nl\/flexographic-ink-additives\/\">Hoe kies je de juiste additieven voor flexografische inkten?<\/a><\/li>\n<li><strong>Related waterborne print-finishing page:<\/strong> <a href=\"https:\/\/longchangchemical.com\/nl\/waterborne-overprint-varnish-additives\/\">How to Choose Additives for Waterborne Overprint Varnishes<\/a><\/li>\n<li><strong>Related packaging page:<\/strong> <a href=\"https:\/\/longchangchemical.com\/nl\/label-ink-additives\/\">How to Choose Additives for Label Inks<\/a><\/li>\n<li><strong>Gerelateerde functiepagina:<\/strong> <a href=\"https:\/\/longchangchemical.com\/nl\/wetting-additives-coatings-inks\/\">Hoe kies je de juiste bevochtigingsmiddelen voor coatings en inkten?<\/a><\/li>\n<li><strong>Gerelateerde functiepagina:<\/strong> <a href=\"https:\/\/longchangchemical.com\/nl\/defoamers-coatings-inks\/\">Hoe kies je de juiste schuimremmers voor coatings en inkten?<\/a><\/li>\n<li><strong>Gerelateerde functiepagina:<\/strong> <a href=\"https:\/\/longchangchemical.com\/nl\/anti-blocking-additives-coatings-inks\/\">Hoe kies je de juiste antiblokkeermiddelen voor coatings en inkten?<\/a><\/li>\n<\/ul>\n<h2>FAQ<\/h2>\n<h3>Which additive should I screen first if a waterborne flexographic ink still is not spreading cleanly?<\/h3>\n<p>Usually 2100, because the supported route is built around very low surface tension and difficult-substrate wetting, which matches a real entry-and-spread problem more directly than a handling or defoaming route.<\/p>\n<h3>When should 3501 move ahead of 2100?<\/h3>\n<p>3501 should move ahead when the ink already transfers directionally but the dried print face still blocks, drags, or handles poorly during rewinding, stacking, lamination, or later contact.<\/p>\n<h3>When does 3062 make more sense than the other two?<\/h3>\n<p>It makes more sense when foam, microbubbles, or air entrainment still dominate the visible defect pattern and the team needs a printing-ink defoamer route rather than another surface-control trial.<\/p>\n<h3>Is this page the same as the broader flexographic-ink additives page?<\/h3>\n<p>No. The broader flexographic page still answers the wider application question across UV, solvent, and water-based systems. This page is narrower and helps waterborne flexographic buyers decide whether the first bottleneck is substrate entry, dried-face handling, or circulation-side foam.<\/p>\n<h3>Does this page make food-contact or regulatory claims for packaging work?<\/h3>\n<p>No. This page stays focused on additive-selection logic for waterborne flexographic workflows.
