Those pages solve different buyer questions.<\/p>\n<p>A waterborne industrial coating project often creates a narrower first-screen decision: <strong>is the main bottleneck substrate wetting, smoother leveling after wetting, or foam collapse and air release?<\/strong> That question shows up across general industrial coatings, protective coatings, and similar factory-applied waterborne systems.

If the waterborne system does not spread cleanly on the substrate, keeps pulling back, or struggles to wet a harder industrial surface, a wetting-first route is often more informative than jumping straight to a broader surface package.<\/p>\n<p>Longchang supports 3071 as a polyether-modified polysiloxane wetting agent with a recommended dosage of <strong>0,1% \u00e0 1,0%<\/strong>. The page allows addition during grinding, stirring, or after production, and supports use in <strong>water-based, solvent, and UV systems<\/strong>. For this page, the key point is not that it fits every system. The key point is that it gives buyers a <strong>clear wetting-first benchmark<\/strong> inside a waterborne industrial-coating project.<\/p>\n<ul>\n<li><strong>Best first-screen use:<\/strong> harder-to-wet industrial substrates and early spread problems<\/li>\n<li><strong>Dosage guidance:<\/strong> 0,1% \u00e0 1,0% de la formulation totale<\/li>\n<li><strong>Addition logic:<\/strong> during grinding, stirring, or after production<\/li>\n<li><strong>Main caution:<\/strong> in water-based systems it may stabilize foam, so do not judge it only by wetting improvement<\/li>\n<\/ul>\n<p>In short, 3071 is the better first move when the coating is not making good enough contact with the substrate.<\/p>\n<h2>Quand CHLUMILE\u00ae 3345 est le meilleur premier choix<\/h2>\n<p>3345 deserves the earlier screen when the buyer is not only chasing substrate wetting. It is the stronger first route when the coating must also lay down <strong>more evenly<\/strong> after it wets. Longchang\u2019s company-supported positioning is more specific here because the product is named and framed directly as a <strong>agent mouillant et nivelant<\/strong>.<\/p>\n<p>The supported page gives 3345 the same <strong>0,1% \u00e0 1,0%<\/strong> dosage range, broad <strong>water-based, solvent, and UV<\/strong> applicability, and flexible addition timing during grinding, stirring, or later addition. Longchang also notes that co-solvents such as <strong>\u00e9ther m\u00e9thylique de dipropyl\u00e8ne glycol<\/strong> can enhance the effect, which makes it a practical screening route when the project needs a more refined wetting-plus-leveling balance instead of only a stronger surfactant push.<\/p>\n<ul>\n<li><strong>Best first-screen use:<\/strong> waterborne industrial finishes that need smoother laydown after wetting<\/li>\n<li><strong>Dosage guidance:<\/strong> 0,1% \u00e0 1,0% de la formulation totale<\/li>\n<li><strong>Addition logic:<\/strong> during grinding, stirring, or after production<\/li>\n<li><strong>Practical note:<\/strong> co-solvent adjustment may improve the effect during development work<\/li>\n<\/ul>\n<p>So 3345 is the cleaner first benchmark when the buyer wants <strong>balanced wetting and leveling<\/strong>, not only stronger wetting.<\/p>\n<h2>Quand CHLUMIAF\u00ae 094 est le meilleur premier choix<\/h2>\n<p>094 should move ahead when the project already has a plausible wetting route but the film keeps failing because of <strong>persistent foam, entrained air, or microbubble-type defects<\/strong>. That is a different job from surface wetting. It is also one that can waste a lot of development time if the team keeps testing more surfactants before solving the foam problem.<\/p>\n<p>Longchang supports 094 as a <strong>polyether silicone defoamer<\/strong> pour <strong>syst\u00e8mes \u00e0 base d&#039;eau uniquement<\/strong>. Its recommended dosage is much lower than the wetting or leveling routes, at <strong>50 \u00e0 500 ppm<\/strong> based on total formulation. The company page also states that direct full-strength addition to the working solution is generally not conducive to dispersion, so the product should usually be <strong>diluted below 60%<\/strong> and then further diluted with water to prepare a working solution for use.<\/p>\n<ul>\n<li><strong>Best first-screen use:<\/strong> persistent foam, microbubbles, or poor air release in waterborne industrial coatings<\/li>\n<li><strong>Dosage guidance:<\/strong> 50 to 500 ppm based on total formulation<\/li>\n<li><strong>Preparation rule:<\/strong> dilute before use rather than adding it full strength into the working solution<\/li>\n<li><strong>System fit:<\/strong> syst\u00e8mes \u00e0 base d&#039;eau uniquement<\/li>\n<\/ul>\n<p>That makes 094 the better first move when the project is failing because of <strong>contr\u00f4le de la mousse<\/strong>, not because of a missing wetting or leveling route.<\/p>\n<h2>Comment les acheteurs doivent choisir avant de demander des \u00e9chantillons<\/h2>\n<h3>1. Start with the first visible failure<\/h3>\n<p>If the coating cannot wet the substrate cleanly, start with 3071. If it wets but still does not level into an even film, move 3345 earlier. If the film quality is being destroyed by foam or trapped air, 094 should move first.<\/p>\n<h3>2. Keep the operating window visible<\/h3>\n<p>3071 and 3345 both have broader system fit on the company pages, but 094 is explicitly a <strong>\u00e0 base d&#039;eau uniquement<\/strong> route. That alone helps keep early screening more disciplined.<\/p>\n<h3>3. Do not confuse related surface problems with the same additive job<\/h3>\n<p>Wetting failure, leveling failure, and foam failure often show up on the same panel, but they are not the same selection problem. Buyers usually get faster answers when they identify which one is the <strong>first cause<\/strong>.<\/p>\n<h3>4. Use the watchpoint, not just the headline benefit<\/h3>\n<p>3071 may stabilize foam in water-based systems. 3345 may need co-solvent support to deliver the best balance. 094 should be diluted before use. Those practical notes often decide the better first route more than the headline product family.<\/p>\n<h3>5. Keep the first round tight<\/h3>\n<p>For most waterborne industrial-coating buyers, one wetting-first route, one wetting-and-leveling route, and one defoamer-first route teach more than an overloaded first panel with too many overlapping additives.<\/p>\n<h2>Itin\u00e9raire recommand\u00e9 pour Longchang \u00e0 partir de cette page<\/h2>\n<ul>\n<li><strong>Aper\u00e7u du cluster\u00a0:<\/strong> <a href=\"https:\/\/longchangchemical.com\/fr\/chlumicryl-coating-ink-additives\/\">CHLUMICRYL\u00ae Additifs pour rev\u00eatements et encres<\/a><\/li>\n<li><strong>Related waterborne application page:<\/strong> <a href=\"https:\/\/longchangchemical.com\/fr\/waterborne-wood-coating-additives\/\">Comment choisir les additifs pour les rev\u00eatements \u00e0 base d&#039;eau pour bois<\/a><\/li>\n<li><strong>Page relative au d\u00e9faut\u00a0:<\/strong> <a href=\"https:\/\/longchangchemical.com\/fr\/coating-defect-additive-selection\/\">Additif mouillant vs additif de nivellement vs antimousse vs tensioactif fluor\u00e9<\/a><\/li>\n<li><strong>Related protective-coating page:<\/strong> <a href=\"https:\/\/longchangchemical.com\/fr\/anti-corrosion-coating-additives\/\">Comment choisir les additifs pour les rev\u00eatements anticorrosion<\/a><\/li>\n<li><strong>3071 product page:<\/strong> <a href=\"https:\/\/longchangchemical.com\/fr\/product\/chlumiwe-3071-organic-silicone-surfactant-organosilicone-wetting-agent\/\">CHLUMIWE\u00ae 3071<\/a><\/li>\n<li><strong>3345 product page:<\/strong> <a href=\"https:\/\/longchangchemical.com\/fr\/product\/chlumile3345-wetting-and-leveling-agent\/\">CHLUMILE\u00ae 3345<\/a><\/li>\n<li><strong>094 product page:<\/strong> <a href=\"https:\/\/longchangchemical.com\/fr\/product\/chlumiaf-094\/\">CHLUMIAF\u00ae 094<\/a><\/li>\n<\/ul>\n<h2>FAQ<\/h2>\n<h3>Which additive should I screen first if a waterborne industrial coating will not wet the substrate well?<\/h3>\n<p>Start with CHLUMIWE\u00ae 3071 when the main early failure is poor wetting or spreading on a difficult industrial surface.<\/p>\n<h3>When is 3345 a better first route than 3071?<\/h3>\n<p>3345 is usually the better first route when the project needs wetting support but the real commercial target is more even film laydown and broader leveling balance.<\/p>\n<h3>When should 094 move ahead of wetting or leveling additives?<\/h3>\n<p>094 should move ahead when persistent foam, entrained air, or microbubble defects are the main barrier to acceptable film quality in a waterborne system.<\/p>\n<h3>Can 094 replace a wetting or leveling additive?<\/h3>\n<p>No. 094 is a defoamer-first route.
