Longchang supports a <strong>0.1% \u81f3 1.0%<\/strong> dosage range, flexible addition during grinding, stirring, or after production, dilution with <strong>water, alcohols, alkanes, and aromatics<\/strong>, and use in <strong>\u7d2b\u5916\u3001\u6eb6\u5242\u548c\u6c34\u57fa<\/strong> systems. The waterborne watchpoint is explicit: it <strong>may have a foam-stabilizing effect<\/strong> in water-based systems.<\/li>\n<li><strong>CHLUMILE\u00ae 3345<\/strong> is positioned directly as a <strong>wetting and leveling agent<\/strong>. Longchang also supports a <strong>0.1% \u81f3 1.0%<\/strong> dosage range, addition during grinding, stirring, or after production, dilution with <strong>water, alcohols, alkanes, and aromatics<\/strong>, and applicability in <strong>\u7d2b\u5916\u3001\u6eb6\u5242\u548c\u6c34\u57fa<\/strong> systems. Longchang further notes that adding co-solvents such as <strong>dipropylene glycol methyl ether<\/strong> can enhance the effect.<\/li>\n<li><strong>CHLUMIAF\u00ae 094<\/strong> is the <strong>defoamer-first route<\/strong>. Longchang supports it for <strong>\u4ec5\u9650\u6c34\u57fa\u7cfb\u7edf<\/strong>, with a much lower dosage band of <strong>50 to 500 ppm<\/strong>, and says it should generally be <strong>diluted before use<\/strong> rather than dropped into the working solution as-is.<\/li>\n<\/ul>\n<p>That is enough product-level separation to build a real shortlist instead of treating all three as vague \u201csurface additives.\u201d<\/p>\n<h2>Quick comparison table: when each route deserves the first screen<\/h2>\n<table>\n<thead>\n<tr>\n<th>Buyer priority<\/th>\n<th>3071<\/th>\n<th>3345<\/th>\n<th>094<\/th>\n<\/tr>\n<\/thead>\n<tbody>\n<tr>\n<td>Main first-screen job<\/td>\n<td>Wetting-first substrate spread and surface contact<\/td>\n<td>Wetting plus leveling balance<\/td>\n<td>Foam collapse and air-release control<\/td>\n<\/tr>\n<tr>\n<td>Supported dosage<\/td>\n<td>0.1% \u81f3 1.0%<\/td>\n<td>0.1% \u81f3 1.0%<\/td>\n<td>50 to 500 ppm<\/td>\n<\/tr>\n<tr>\n<td>System window<\/td>\n<td>UV, solvent, water-based<\/td>\n<td>UV, solvent, water-based<\/td>\n<td>\u4ec5\u9650\u6c34\u6027<\/td>\n<\/tr>\n<tr>\n<td>\u52a0\u6cd5\u903b\u8f91<\/td>\n<td>Grinding, stirring, or after production<\/td>\n<td>Grinding, stirring, or after production<\/td>\n<td>Usually pre-dilute before use<\/td>\n<\/tr>\n<tr>\n<td>Best use when<\/td>\n<td>The coating is not spreading or wetting the substrate cleanly<\/td>\n<td>The coating wets but still needs smoother, more even laydown<\/td>\n<td>Foam, microbubbles, or air release are ruining the film<\/td>\n<\/tr>\n<tr>\n<td>\u4e3b\u8981\u89c2\u5bdf\u70b9<\/td>\n<td>May stabilize foam in water-based systems<\/td>\n<td>Still not a substitute for a true defoamer if bubbles are the main defect<\/td>\n<td>Not a substitute for a real wetting or leveling route<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<h2>When CHLUMIWE\u00ae 3071 is the better first move<\/h2>\n<p>3071 should move first when the waterborne coating is failing at the <strong>very first contact step<\/strong>. If the formula pulls back, spreads too slowly, or does not wet the substrate cleanly enough to judge the rest of the package, a wetting-first route is usually more informative than jumping immediately to a broader balancing additive.<\/p>\n<p>That is what makes 3071 commercially useful. Longchang supports it as a polyether-modified polysiloxane wetting agent with a low-surface-tension profile, broad dilution flexibility, and multiple addition paths. The key practical benefit for the buyer is not that it can go into many systems. The key benefit is that it provides a clean benchmark for <strong>substrate-contact problems<\/strong>.<\/p>\n<p>3071 is the stronger first route when:<\/p>\n<ul>\n<li>the waterborne coating is still struggling to spread over a harder substrate,<\/li>\n<li>the team needs to learn whether the problem is really <strong>wetting failure<\/strong> before adding more complexity,<\/li>\n<li>the lab wants a route that can be screened early during grinding or after production, or<\/li>\n<li>the coating project spans more than one future system window, even though the current trial is waterborne.<\/li>\n<\/ul>\n<p>The most important watchpoint is also clear. Longchang says 3071 may stabilize foam in water-based systems. So if wetting improves but bubble pressure rises, that does not mean 3071 failed. It means the buyer may have solved one problem while exposing another.<\/p>\n<h2>When CHLUMILE\u00ae 3345 is the better first move<\/h2>\n<p>3345 deserves the earlier screen when the coating team no longer needs only stronger wetting. It becomes the better benchmark when the project needs a more <strong>balanced wetting-and-leveling result<\/strong>. That matters in many waterborne finishes where the substrate can already be wetted reasonably well, but the final laydown still looks less even, less calm, or less commercially acceptable than the buyer wants.<\/p>\n<p>Longchang\u2019s supported evidence is more specific here than with a generic surfactant. 3345 is named and positioned directly as a wetting and leveling agent. The company page keeps the same <strong>0.1% \u81f3 1.0%<\/strong> dosage window and broad system applicability, but also adds the practical note that co-solvents such as <strong>dipropylene glycol methyl ether<\/strong> can enhance the effect.<\/p>\n<p>3345 is usually the better first route when:<\/p>\n<ul>\n<li>the coating wets, but the film still needs smoother and more even laydown,<\/li>\n<li>the buyer wants to reduce the gap between initial substrate contact and final film appearance,<\/li>\n<li>the team wants a broader surface-balance benchmark before moving to more specialized additives, or<\/li>\n<li>development work already includes co-solvent adjustment and leveling balance, not just raw wetting correction.<\/li>\n<\/ul>\n<p>In short, 3345 is not simply \u201c3071 but a little different.\u201d It is the more logical first screen when the decision is no longer only about getting the coating onto the surface, but about getting it to settle there better.<\/p>\n<h2>When CHLUMIAF\u00ae 094 is the better first move<\/h2>\n<p>094 should move to the front when the coating already has a workable wetting route, but the film is still being limited by <strong>foam<\/strong>, <strong>microbubbles<\/strong>\uff0c \u6216\u8005 <strong>poor air release<\/strong>. In that case, testing another wetting additive first can waste time because the real defect is not in initial spread. It is in gas management inside the waterborne system.<\/p>\n<p>Longchang supports 094 as a waterborne defoamer with a very different operating pattern from 3071 or 3345. The dosage is not 0.1% to 1.0%, but <strong>50 to 500 ppm<\/strong>. The system window is not broad, but <strong>\u4ec5\u6c34\u6027<\/strong>. And the use method is not casual direct addition, because Longchang says the defoamer should generally be <strong>diluted before use<\/strong>.<\/p>\n<p>094 is the stronger first route when:<\/p>\n<ul>\n<li>the waterborne coating is already showing persistent bubbles, pinholes, or microfoam,<\/li>\n<li>the lab needs a true defoamer benchmark instead of another surface-wetting trial,<\/li>\n<li>the process window is clearly waterborne and not a mixed-system development project, or<\/li>\n<li>air release is blocking film quality more than substrate contact is.<\/li>\n<\/ul>\n<p>094 should not be used as a substitute for wetting or leveling logic. It is the cleaner choice when the buyer already knows the real problem is <strong>foam behavior<\/strong>, not simply surface contact.<\/p>\n<h2>How buyers should choose before the first sample round<\/h2>\n<h3>1. Identify where the defect starts<\/h3>\n<p>If the coating fails when it first meets the substrate, start with 3071. If it wets but still does not settle or level the way the buyer wants, move first to 3345. If the film is being damaged by bubbles or air release, start with 094.<\/p>\n<h3>2. Do not compare dosage numbers out of context<\/h3>\n<p>3071 and 3345 both sit in the <strong>0.1% \u81f3 1.0%<\/strong> range. 094 sits in a <strong>ppm-level<\/strong> range. That does not make 094 \u201cstronger\u201d in a generic sense. It means it is solving a different problem class.<\/p>\n<h3>3. Keep the addition method in the decision<\/h3>\n<p>3071 and 3345 can be added during grinding, stirring, or after production. 094 usually needs a pre-dilution step. Buyers should include that process handling difference in the shortlist, not treat it as a minor lab detail.<\/p>\n<h3>4. Use waterborne logic carefully<\/h3>\n<p>One of the most important distinctions in this comparison is that 3071 may stabilize foam in water-based systems, while 094 exists specifically to solve foam trouble in water-based systems. That means the first-screen sequence matters. Solving wetting first can sometimes reveal the need for a separate foam-control step.<\/p>\n<h3>5. Keep the page type honest<\/h3>\n<p>This is not a broad \u201cbest additive for waterborne coatings\u201d page. It is a shortlist article for buyers already deciding between three specific Longchang routes. That narrower comparison intent is exactly why this page can coexist cleanly with broader application and defect pages.<\/p>\n<h2>Recommended Longchang path from this comparison<\/h2>\n<ul>\n<li><strong>\u5148\u5f04\u6e7f\u8def\u7ebf\uff1a<\/strong> <a href=\"https:\/\/longchangchemical.com\/zh\/product\/chlumiwe-3071-organic-silicone-surfactant-organosilicone-wetting-agent\/\">CHLUMIWE\u00ae 3071<\/a><\/li>\n<li><strong>Wetting-plus-leveling route:<\/strong> <a href=\"https:\/\/longchangchemical.com\/zh\/product\/chlumile3345-wetting-and-leveling-agent\/\">CHLUMILE\u00ae 3345<\/a><\/li>\n<li><strong>Waterborne defoamer route:<\/strong> <a href=\"https:\/\/longchangchemical.com\/zh\/product\/chlumiaf-094\/\">CHLUMIAF\u00ae 094<\/a><\/li>\n<li><strong>\u76f8\u5173\u5e94\u7528\u9875\u9762\uff1a<\/strong> <a href=\"https:\/\/longchangchemical.com\/zh\/waterborne-industrial-coating-additives\/\">How to Choose Surface Additives for Waterborne Industrial Coatings<\/a><\/li>\n<li><strong>Related cluster page:<\/strong> <a href=\"https:\/\/longchangchemical.com\/zh\/chlumicryl-coating-ink-additives\/\">CHLUMICRYL\u00ae \u6d82\u5c42\u548c\u6cb9\u58a8\u6dfb\u52a0\u5242<\/a><\/li>\n<li><strong>\u76f8\u5173\u529f\u80fd\u9875\u9762\uff1a<\/strong> <a href=\"https:\/\/longchangchemical.com\/zh\/wetting-additives-coatings-inks\/\">\u5982\u4f55\u9009\u62e9\u6d82\u6599\u548c\u6cb9\u58a8\u7684\u6da6\u6e7f\u52a9\u5242<\/a><\/li>\n<li><strong>\u76f8\u5173\u529f\u80fd\u9875\u9762\uff1a<\/strong> <a href=\"https:\/\/longchangchemical.com\/zh\/leveling-additives-coatings-inks\/\">\u5982\u4f55\u9009\u62e9\u6d82\u6599\u548c\u6cb9\u58a8\u7684\u6d41\u5e73\u52a9\u5242<\/a><\/li>\n<li><strong>\u76f8\u5173\u529f\u80fd\u9875\u9762\uff1a<\/strong> <a href=\"https:\/\/longchangchemical.com\/zh\/defoamers-coatings-inks\/\">\u5982\u4f55\u9009\u62e9\u6d82\u6599\u548c\u6cb9\u58a8\u7528\u6d88\u6ce1\u5242<\/a><\/li>\n<\/ul>\n<h2>\u5e38\u89c1\u95ee\u9898<\/h2>\n<h3>Which product should I test first if the coating is not spreading over the substrate?<\/h3>\n<p>Start with CHLUMIWE\u00ae 3071.
