Start with <a href=\"https:\/\/longchangchemical.com\/pt\/product\/chlumiwe-100\/\"><strong>CHLUMIWE\u00ae 2100<\/strong><\/a> when the waterborne screen ink still needs stronger <strong>molhamento do substrato<\/strong>, <strong>spread<\/strong>, and lower-surface-tension entry on a difficult surface.

Start with <a href=\"https:\/\/longchangchemical.com\/pt\/product\/agesin-we-d912r-defoamer\/\"><strong>CHLUMICRYL\u00ae WE-D912R<\/strong><\/a> when the real blocker is <strong>microbubbles, foam retention, or compatibility-sensitive bubble cleanup<\/strong> in a water-based screen-ink route.<\/p>\n<p>This page stays inside the redirected <strong>CHLUMICRYL\u00ae Aditivos para tintas e revestimentos<\/strong> direction and does <strong>not<\/strong> fall back to the older photoinitiator cluster. It also is not a duplicate of Longchang\u2019s already-live <a href=\"https:\/\/longchangchemical.com\/pt\/screen-ink-additives\/\">screen ink additives<\/a> page or the nearby <a href=\"https:\/\/longchangchemical.com\/pt\/waterborne-overprint-varnish-additives\/\">waterborne overprint varnish additives<\/a> page. It answers a narrower B2B question: <strong>which additive deserves the first trial when the ink is specifically waterborne, printed by screen process, and still not giving a clean result on the target surface?<\/strong><\/p>\n<h2>Why waterborne screen inks deserve their own additive page<\/h2>\n<p>A <strong>waterborne screen ink<\/strong> sits in a tighter buyer lane than a broad screen-ink article because the system has to keep together <strong>water-based process behavior<\/strong>, <strong>screen-print laydown<\/strong>, e <strong>printed-face handling after drying<\/strong>. It also sits in a different lane from waterborne overprint varnish work because the buyer is not only managing a thin finish layer over an existing print. The ink itself still has to spread, transfer, dry, and handle correctly as the printed film.<\/p>\n<p>That creates a different first-screen question from the broader screen-ink page. In practical lab work, the first additive decision often needs to separate a <strong>difficult-surface wetting problem<\/strong> from a <strong>print-face anti-sticking and handling problem<\/strong>, and both from a true <strong>water-based bubble-cleanup problem<\/strong>. Those are not the same first screen, even when the same printed panel or sheet seems to show all three symptoms at once.<\/p>\n<p>General industry framing supports that split conservatively. Waterborne screen-print systems are often judged first by how cleanly the ink wets the substrate, whether the dried print face still sticks or drags, and whether entrained air keeps disturbing film appearance or process 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>tens\u00e3o superficial muito baixa<\/strong>, suitability for <strong>difficult-to-wet substrates<\/strong>, and applicability across <strong>UV<\/strong>, <strong>solvente<\/strong>, e <strong>sistemas \u00e0 base de \u00e1gua<\/strong>. The current company-supported route also says that, with a small amount added, it will <strong>n\u00e3o produz espuma est\u00e1vel sob dispers\u00e3o em alta velocidade<\/strong>, which is commercially useful in a waterborne printing window where foam sensitivity already matters.<\/li>\n<li><strong>CHLUMIAG\u00ae 3501<\/strong> is the broader <strong>print-face anti-sticking and handling route<\/strong>. Longchang directly lists it for <strong>tintas de impress\u00e3o<\/strong>, <strong>tintas para impressoras jato de tinta<\/strong>, <strong>tintas de serigrafia<\/strong>, <strong>vernizes de sobreimpress\u00e3o<\/strong>, <strong>revestimentos de libera\u00e7\u00e3o<\/strong>, e <strong>anti-sticking-agent use<\/strong>. The current company page also supports use across <strong>UV<\/strong>, <strong>solvente<\/strong>, e <strong>sistemas \u00e0 base de \u00e1gua<\/strong>, and says it can be added at <strong>any stage<\/strong> or later.<\/li>\n<li><strong>CHLUMICRYL\u00ae WE-D912R<\/strong> is supported as a <strong>water-borne emulsion defoamer<\/strong> para <strong>water-based paints<\/strong>, <strong>water-based inks<\/strong>, <strong>vernizes de sobreimpress\u00e3o<\/strong>, e <strong>acrylic overprint varnishes<\/strong>. Longchang directly highlights <strong>microbubble suppression<\/strong>, <strong>excelente compatibilidade<\/strong>, and suitability for <strong>medium- and high-viscosity systems<\/strong>, with a supported dosage range of <strong>0,1% a 1,0%<\/strong>.<\/li>\n<\/ul>\n<p>That is enough company-supported separation to build a real buyer page without inventing unsupported screen-print-specific product facts. The goal is not to pretend one additive can solve every waterborne screen-ink complaint. The goal is to help the buyer choose the <strong>first better trial route<\/strong>.<\/p>\n<h2>Tabela de compara\u00e7\u00e3o r\u00e1pida: qual rota merece aparecer em primeiro lugar?<\/h2>\n<table>\n<thead>\n<tr>\n<th>Buyer priority in waterborne screen inks<\/th>\n<th>Melhor primeira rota<\/th>\n<th>Por que ele deve ser o primeiro?<\/th>\n<th>Posto de observa\u00e7\u00e3o principal<\/th>\n<\/tr>\n<\/thead>\n<tbody>\n<tr>\n<td>The waterborne screen ink still hesitates, pulls back, or spreads weakly on the target substrate<\/td>\n<td><a href=\"https:\/\/longchangchemical.com\/pt\/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 ink already prints directionally, but the dried print face still sticks, drags, blocks, or handles poorly<\/td>\n<td><a href=\"https:\/\/longchangchemical.com\/pt\/product\/chlumiag-3501\/\">CHLUMIAG\u00ae 3501<\/a><\/td>\n<td>Longchang directly supports it for screen printing inks, anti-sticking use, and broader downstream handling logic across water-based systems<\/td>\n<td>Do not treat it as a substitute for real wetting correction when the ink still cannot enter the surface cleanly<\/td>\n<\/tr>\n<tr>\n<td>Entrained air, foam retention, or microbubbles are still corrupting transfer or final film appearance<\/td>\n<td><a href=\"https:\/\/longchangchemical.com\/pt\/product\/agesin-we-d912r-defoamer\/\">CHLUMICRYL\u00ae WE-D912R<\/a><\/td>\n<td>Longchang directly positions it for water-based inks and highlights compatibility-led microbubble suppression in waterborne systems<\/td>\n<td>It is a water-based bubble-control route, not the first answer to surface slip or difficult-substrate wetting<\/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 screen-ink 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 screen-printing teams often see more than one complaint at once. A weakly wetting waterborne ink can also look rough, unstable, or bubble-prone simply because the film never settled correctly on the surface in the first place. If the substrate-entry route is still wrong, it becomes harder to interpret later print-face or defoaming trials.<\/p>\n<ul>\n<li><strong>Melhor uso na primeira tela:<\/strong> difficult-substrate wetting and spread in waterborne screen inks<\/li>\n<li><strong>Ajuste do sistema:<\/strong> the current company route supports UV, solvent, and water-based systems<\/li>\n<li><strong>Principal ponto forte:<\/strong> a practical first route when the buyer still needs lower surface tension and cleaner entry on the target surface<\/li>\n<li><strong>Aten\u00e7\u00e3o principal:<\/strong> use it when the dominant problem is wetting and spread, not when the ink already lands directionally and the real complaint is sticking or bubble cleanup<\/li>\n<\/ul>\n<p>In short, 2100 is the better first move when the question is still <strong>how the waterborne screen 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 prints 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 downstream contact pressure on the printed face.<\/p>\n<p>That matters in waterborne screen inks because many printed surfaces are stacked, contacted, overprinted, converted, or handled soon after drying. Those downstream steps can expose a different additive problem from the original laydown 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>tintas de serigrafia<\/strong>, <strong>tintas de impress\u00e3o<\/strong>, <strong>vernizes de sobreimpress\u00e3o<\/strong>, <strong>revestimentos de libera\u00e7\u00e3o<\/strong>, e <strong>anti-sticking use<\/strong>, while staying open across <strong>UV<\/strong>, <strong>solvente<\/strong>, e <strong>sistemas \u00e0 base de \u00e1gua<\/strong>.<\/p>\n<ul>\n<li><strong>Melhor uso na primeira tela:<\/strong> anti-sticking, release, and downstream handling control after the waterborne screen ink already prints directionally<\/li>\n<li><strong>Ajuste do sistema:<\/strong> UV, solvent, and water-based systems on the current public page<\/li>\n<li><strong>Principal ponto forte:<\/strong> one route that already supports screen-printing use plus broader anti-sticking and handling logic<\/li>\n<li><strong>Aten\u00e7\u00e3o principal:<\/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 screen-ink project needs a <strong>handling-first cleanup route<\/strong> after the print already lands acceptably.<\/p>\n<h2>When CHLUMICRYL\u00ae WE-D912R is the better first move<\/h2>\n<p><strong>WE-D912R<\/strong> should move ahead first when the waterborne screen ink is being limited by <strong>microbubbles<\/strong>, <strong>foam retention<\/strong>, ou <strong>air-release instability<\/strong>. In those cases, a better wetting route or a better anti-sticking route usually will not give the team an honest film read until the bubble problem is under control.<\/p>\n<p>Longchang\u2019s product page is direct here. WE-D912R is supported specifically as a <strong>water-borne emulsion defoamer<\/strong> para <strong>water-based inks<\/strong> and nearby waterborne finishing routes, and the product is positioned around <strong>microbubble suppression<\/strong> com <strong>excelente compatibilidade<\/strong>.

Start with the real first failure on the printed film<\/h3>\n<p>If the waterborne screen ink still hesitates or pulls back on the substrate, start with 2100. If the ink already prints directionally but still sticks or drags after drying, move 3501 forward. If foam or microbubbles are still corrupting the print read, start with WE-D912R.<\/p>\n<h3>2. Keep surface entry separate from dried-face handling<\/h3>\n<p>A waterborne screen ink that cannot wet the substrate cleanly and a waterborne screen ink that prints acceptably but still handles poorly are not the same additive problem. Separating those routes early usually makes the first trial set much more honest.<\/p>\n<h3>3. Keep bubble cleanup separate from both surface routes<\/h3>\n<p>Microbubble control is not just a smaller version of wetting correction or slip control. If entrained air is still sitting in the film, it can distort how the team reads every later additive.<\/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. WE-D912R brings direct water-based bubble cleanup. 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 screen-ink buyers, one <strong>2100 wetting route<\/strong>, um <strong>3501 handling route<\/strong>e um <strong>WE-D912R bubble-control route<\/strong> teach more than an overloaded first screen filled with partially overlapping additives.<\/p>\n<h2>Caminho recomendado para Longchang a partir desta p\u00e1gina<\/h2>\n<ul>\n<li><strong>Rota de molhar:<\/strong> <a href=\"https:\/\/longchangchemical.com\/pt\/product\/chlumiwe-100\/\">CHLUMIWE\u00ae 2100<\/a><\/li>\n<li><strong>Handling route:<\/strong> <a href=\"https:\/\/longchangchemical.com\/pt\/product\/chlumiag-3501\/\">CHLUMIAG\u00ae 3501<\/a><\/li>\n<li><strong>Bubble-control route:<\/strong> <a href=\"https:\/\/longchangchemical.com\/pt\/product\/agesin-we-d912r-defoamer\/\">CHLUMICRYL\u00ae WE-D912R<\/a><\/li>\n<li><strong>Vis\u00e3o geral do cluster:<\/strong> <a href=\"https:\/\/longchangchemical.com\/pt\/chlumicryl-coating-ink-additives\/\">CHLUMICRYL\u00ae Aditivos para tintas e revestimentos<\/a><\/li>\n<li><strong>Related broad page:<\/strong> <a href=\"https:\/\/longchangchemical.com\/pt\/screen-ink-additives\/\">Como escolher aditivos para tintas serigr\u00e1ficas<\/a><\/li>\n<li><strong>Related waterborne print-finishing page:<\/strong> <a href=\"https:\/\/longchangchemical.com\/pt\/waterborne-overprint-varnish-additives\/\">How to Choose Additives for Waterborne Overprint Varnishes<\/a><\/li>\n<li><strong>P\u00e1gina de fun\u00e7\u00f5es relacionadas:<\/strong> <a href=\"https:\/\/longchangchemical.com\/pt\/wetting-additives-coatings-inks\/\">Como escolher aditivos umectantes para revestimentos e tintas<\/a><\/li>\n<li><strong>P\u00e1gina de fun\u00e7\u00f5es relacionadas:<\/strong> <a href=\"https:\/\/longchangchemical.com\/pt\/defoamers-coatings-inks\/\">Como escolher antiespumantes para revestimentos e tintas<\/a><\/li>\n<li><strong>P\u00e1gina de fun\u00e7\u00f5es relacionadas:<\/strong> <a href=\"https:\/\/longchangchemical.com\/pt\/anti-blocking-additives-coatings-inks\/\">Como escolher aditivos antiaglomerantes para revestimentos e tintas<\/a><\/li>\n<\/ul>\n<h2>PERGUNTAS FREQUENTES<\/h2>\n<h3>Which additive should I screen first if a waterborne screen 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 bubble-only route.<\/p>\n<h3>When should 3501 move ahead of 2100?<\/h3>\n<p>3501 should move ahead when the ink already prints directionally but the dried print face still sticks, drags, blocks, or handles poorly during downstream contact.<\/p>\n<h3>When does WE-D912R make more sense than the other two?<\/h3>\n<p>It makes more sense when microbubbles, foam retention, or compatibility-sensitive air-release problems still dominate the visible defect pattern and the team needs a water-based ink defoamer route rather than another surface-control trial.<\/p>\n<h3>Is this page the same as the broader screen-ink additives page?<\/h3>\n<p>No. The broader screen-ink page still answers the wider application question across UV, solvent, and water-based systems. This page is narrower and helps waterborne screen-ink buyers decide whether the first problem is substrate entry, dried-face handling, or water-based bubble cleanup.<\/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 screen-print workflows. Any compliance, migration, or final end-use qualification still needs separate formulation and regulatory review.<\/p>\n<h2>Pr\u00f3ximo passo<\/h2>\n<p>If your waterborne screen-ink project is stuck between <strong>weak surface entry<\/strong>, <strong>dried-face handling pressure<\/strong>, e <strong>microbubble carry-through<\/strong>, stop treating them as the same additive request.
