Chemical reaction methods involve adding specific reagents to the foam system to cause a chemical reaction with the foaming agent, generating substances that are insoluble in water, thereby reducing the concentration of surfactant in the liquid film and ultimately causing the foam to break. However, this method faces the dilemma of difficulty in determining the composition of the foaming agent, and the insoluble substances produced may damage the system equipment. In various industries today, the addition of defoamers such as <a href=\"https:\/\/longchangchemical.com\/zh\/product\/chlumiaf-094\/\">CHLUMIAF 094 Defoamer<\/a> \u548c <a href=\"https:\/\/longchangchemical.com\/zh\/product\/chlumiaf-3062\/\">CHLUMIAF 3062 Defoamer<\/a> is the most widely used means of defoaming. Its greatest advantage is its high defoaming efficiency and extreme ease of use, but the key is to find a suitable and highly effective defoamer

lc-commercial-start --><\/p>\n<h2>A practical formulation view of printing and ink-processing topics<\/h2>\n<p>Ink performance problems are often multi-variable problems. Teams generally move faster when they screen transfer, flow, drying or curing, and substrate hold together instead of changing one raw material at a time without a clear decision frame.<\/p>\n<ul>\n<li><strong>Define the real process bottleneck:<\/strong> poor transfer, drying problems, skinning, and color instability often need different corrective routes.<\/li>\n<li><strong>Check viscosity inside the print process:<\/strong> an ink that looks fine in the container can behave very differently on the machine.<\/li>\n<li><strong>Review substrate compatibility:<\/strong> paper, film, metalized surfaces, and laminates often require different balance points.<\/li>\n<li><strong>Use post-print checks as part of selection:<\/strong> scratch resistance, tape adhesion, lamination behavior, and storage stability are usually as important as the fresh-print appearance.<\/li>\n<\/ul>\n<h3>Recommended product references<\/h3>\n<ul>\n<li><strong><a href=\"https:\/\/longchangchemical.com\/zh\/product\/photoinitiator-lap-cas-85073-19-4\/\">CHLUMINIT LAP<\/a>:<\/strong> A strong option when blue-light response or advanced curing windows are under review.<\/li>\n<li><strong><a href=\"https:\/\/longchangchemical.com\/zh\/product\/chlumiaf-094\/\">CHLUMIAF 094<\/a>:<\/strong> A balanced defoamer reference for waterborne coatings and many general foam-control screens.<\/li>\n<li><strong><a href=\"https:\/\/longchangchemical.com\/zh\/product\/chlumiaf-3062\/\">CHLUMIAF 3062<\/a>:<\/strong> Useful when printing-ink and UV-ink compatibility matter in the defoaming screen.<\/li>\n<li><strong><a href=\"https:\/\/longchangchemical.com\/zh\/product\/chlumiaf-3037\/\">CHLUMIAF 3037<\/a>:<\/strong> A stronger process-defoaming option when persistent foam survives harsher conditions.<\/li>\n<\/ul>\n<h3>FAQ for buyers and formulators<\/h3>\n<p><strong>Why do many ink problems require more than one formulation change?<\/strong><br \/>Because flow, transfer, drying, adhesion, and appearance interact, so improving one of them can sometimes worsen another if the full system is not reviewed together.<\/p>\n<p><strong>Should rheology be judged only by a single viscosity number?<\/strong><br \/>Not usually.
