This page stays inside the redirected <strong>CHLUMICRYL\u00ae coating-and-ink-additives<\/strong> direction and does <strong>nem<\/strong> drift back to the older photoinitiator cluster.

Those pages explain the families or the defect branch. This new page answers the tighter buyer question that comes after that: <strong>which one of these three supported routes deserves the first sample round?<\/strong><\/p>\n<h2>Why this 3071 vs 3345 vs 3467 comparison deserves its own page<\/h2>\n<p>In practical formulation work, these three products often get pulled into the same conversation because all three touch surface behavior. That is exactly why buyers can lose time. A project with poor first-contact spread on metal or plastic should not start from the same first additive screen as a project where the film already reaches the surface but still looks visually unsettled. Neither of those should be confused with a crater-sensitive system that really needs a more compatibility-first route.<\/p>\n<p>General industry framing supports that separation. Surface-additive troubleshooting often starts by asking whether the failure begins at <strong>substrate entry<\/strong>, at <strong>film laydown and leveling<\/strong>, or in a more <strong>formulation-sensitive crater \/ fisheye \/ pullback window<\/strong>. This page uses that outside framing only conservatively. The product-specific claims below 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 3071<\/strong> is supported by Longchang as a <strong>poli\u00e9terrel m\u00f3dos\u00edtott poliszilox\u00e1n<\/strong> with recommended dosage of <strong>0,1%-t\u0151l 1,0%-ig<\/strong>.

Longchang also states that this route prioritizes <strong>rendszerkompatibilit\u00e1s<\/strong>, even if the feel is slightly less refined.<\/li>\n<\/ul>\n<p>That is enough company-supported separation to build a real buyer-selection page. The goal here is not to declare one universal winner. The goal is to help a buyer choose the <strong>first better screening route<\/strong> based on what the coating or ink actually is failing to do.<\/p>\n<h2>Gyors \u00f6sszehasonl\u00edt\u00f3 t\u00e1bl\u00e1zat: melyik \u00fatvonal \u00e9rdemli meg az els\u0151 k\u00e9perny\u0151t?<\/h2>\n<table>\n<thead>\n<tr>\n<th>Observed formulation problem<\/th>\n<th>Legjobb els\u0151 \u00fatvonal<\/th>\n<th>Mi\u00e9rt tartozik az els\u0151 helyre<\/th>\n<th>F\u0151 megfigyel\u00e9si pont<\/th>\n<\/tr>\n<\/thead>\n<tbody>\n<tr>\n<td>The coating or ink still struggles with first-contact spread, difficult-surface coverage, or weak substrate entry<\/td>\n<td><a href=\"https:\/\/longchangchemical.com\/hu\/product\/chlumiwe-3071-organic-silicone-surfactant-organosilicone-wetting-agent\/\">CHLUMIWE\u00ae 3071<\/a><\/td>\n<td>Longchang supports it directly around spreadability, wetting, penetration, and broad cross-system use<\/td>\n<td>Water-based systems still need to watch for possible foam stabilization<\/td>\n<\/tr>\n<tr>\n<td>The film already reaches the surface, but still needs calmer visible laydown and a broader wetting-plus-leveling route<\/td>\n<td><a href=\"https:\/\/longchangchemical.com\/hu\/product\/chlumile3345-wetting-and-leveling-agent\/\">CHLUMILE\u00ae 3345<\/a><\/td>\n<td>Longchang positions it directly as a wetting and leveling agent with flexible process-stage addition<\/td>\n<td>Use it when the main issue is broader laydown cleanup, not when crater-sensitive compatibility is the real blocker<\/td>\n<\/tr>\n<tr>\n<td>The defect behaves more like crater, fisheye, pullback, or compatibility-sensitive film instability inside the formulation<\/td>\n<td><a href=\"https:\/\/longchangchemical.com\/hu\/product\/chlumiag3467-silicone-leveling-agents\/\">CHLUMIAG\u00ae 3467<\/a><\/td>\n<td>The supported route keeps together anti-cratering, leveling, wetting, and system-compatibility logic<\/td>\n<td>Its supported logic prioritizes compatibility more than a more refined final feel<\/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 project still is failing at <strong>surface entry<\/strong>. This is the stronger first route when the coating or ink still beads, hesitates, or spreads unevenly on plastic, metal, coated stock, or another difficult surface. If the liquid does not reach the substrate correctly, later-leveling discussions can become noisy because the film never had a fair first-contact start.<\/p>\n<p>That supported logic is commercially useful because Longchang does not position 3071 only as a vague silicone aid.

This is the stronger route when the buyer no longer needs a pure first-contact wetting answer and instead needs a broader <strong>wetting-and-leveling cleanup path<\/strong> for visible film formation.<\/p>\n<p>That distinction matters because many labs collapse 3071 and 3345 into the same shortlist too early. The supported product logic says they should not be treated the same. 3345 is framed directly as a <strong>wetting and leveling agent<\/strong>, and Longchang supports a flexible addition window during grinding, stirring, or after production. That makes it commercially useful when the film already enters the surface directionally but still needs a calmer final read.<\/p>\n<ul>\n<li><strong>Best first-screen use:<\/strong> broader wetting-plus-leveling cleanup after surface entry is already directionally acceptable<\/li>\n<li><strong>Supported dosage:<\/strong> 0,1% - 1,0% a teljes k\u00e9sz\u00edtm\u00e9nyb\u0151l<\/li>\n<li><strong>F\u0151 er\u0151ss\u00e9g:<\/strong> a more balanced route for surface wetting and visible laydown together<\/li>\n<li><strong>Main practical note:<\/strong> Longchang says suitable co-solvents can enhance the effect<\/li>\n<\/ul>\n<p>So 3345 is the better first move when the issue has shifted from <strong>getting onto the surface<\/strong> a  c\u00edmre. <strong>forming a smoother, calmer film on it<\/strong>.<\/p>\n<h2>When CHLUMIAG\u00ae 3467 is the better first move<\/h2>\n<p>3467 deserves the earlier screen when the complaint reads more like a <strong>compatibility-sensitive crater or fisheye problem<\/strong> than a simple spreading problem. This is the better first route when the coating or ink already reaches the surface but still shows <strong>craters<\/strong>, <strong>pullback<\/strong>, <strong>fisheyes<\/strong>, or a more unstable laydown pattern that points to a formulation-sensitive anti-cratering job.<\/p>\n<p>Longchang\u2019s current product page is especially useful here because 3467 is not positioned only as a feel additive.

Start with the real first failure<\/h3>\n<p>If the material still will not spread or cover the substrate correctly, start with 3071. If it spreads but still looks uneven or visually unsettled, start with 3345. If it already spreads yet still breaks into crater or fisheye behavior, move 3467 forward first.<\/p>\n<h3>2. Keep wetting logic separate from leveling logic<\/h3>\n<p>A coating that will not enter the surface and a coating that enters but still levels poorly are not asking the same question. Keeping those routes separate usually makes the first sample round much cleaner.<\/p>\n<h3>3. Keep compatibility-first crater rescue separate from both<\/h3>\n<p>Crater-sensitive pullback or fisheye behavior is not just a slightly worse leveling problem. If the formulation still looks compatibility-sensitive, 3467 belongs in its own first screen.<\/p>\n<h3>4. Respect the product watchpoints<\/h3>\n<p>3071 may stabilize foam in water-based systems. 3345 gains practical flexibility from its broad addition window and co-solvent support. 3467 should be judged through its compatibility-first logic, not only by final feel. Those watchpoints are part of the commercial selection path.<\/p>\n<h3>5.
