The strongest commercial choice is the one that fixes the real problem without creating a new one.<\/p>\n<p><!-- lc-qa-end --><\/p>\n<p>Esistono molti indicatori per misurare le propriet\u00e0 fisiche e chimiche di una resina. Per l'industria degli inchiostri, i seguenti aspetti dovrebbero essere di interesse.<\/p>\n<p>(1) la viscosit\u00e0 della resina<br \/>\nLa viscosit\u00e0 della resina influisce in larga misura sulla viscosit\u00e0 dell'inchiostro; nella scelta della resina si deve tenere conto dell'entit\u00e0 della sua viscosit\u00e0.<\/p>\n<p>&nbsp;<\/p>\n<p>(2) La solubilit\u00e0 della resina nel solvente<br \/>\nNella produzione di inchiostro, la necessit\u00e0 di aggiungere una certa quantit\u00e0 di solvente nella resina per regolare la viscosit\u00e0 e altri indicatori, quindi la resina pu\u00f2 essere completamente sciolta nel solvente selezionato o nell'olio minerale, \u00e8 il requisito fondamentale per la produzione di inchiostro;.<\/p>\n<p>(3) il rilascio del solvente nella resina<br \/>\nIl rilascio del solvente nella resina si riferisce alla velocit\u00e0 con cui il solvente viene rilasciato dalla resina. Ci\u00f2 influisce sulla velocit\u00e0 di essiccazione dell'inchiostro. Ci\u00f2 \u00e8 legato alla resina stessa, con prestazioni di volatilit\u00e0 del solvente buone o cattive, ma anche alla resina e al solvente mescolati al processo di preparazione e ad altri fattori.<\/p>\n<p>(4) Il colore della resina<br \/>\nLa resina deve essere incolore o di colore chiaro, per evitare che il colore dell'inchiostro sia dovuto al colore della resina.<\/p>\n<p>(5) Resistenza all'acqua della resina<br \/>\nLa resistenza all'acqua della resina influisce sulla resistenza all'acqua dell'inchiostro, in particolare per quanto riguarda l'inchiostro da stampa offset, la scarsa resistenza all'acqua dell'inchiostro provoca emulsioni, lastre di pasta, non sotto l'inchiostro e altri fenomeni. Gli inchiostri a base d'acqua utilizzati nella resina richiedono buone prestazioni di diluizione dell'acqua, ma nel substrato dopo la pellicola non possono essere dissolti in acqua.<\/p>\n<p><!-- lc-commercial-start --><\/p>\n<h2>How buyers usually evaluate coating and ink additives<\/h2>\n<p>Additive selection is usually most effective when the team defines the defect first and then screens compatibility, dosage range, and process stage. That is often much more reliable than choosing only by chemistry family or by a single dramatic lab result.<\/p>\n<ul>\n<li><strong>Start from the defect, not the additive name:<\/strong> wetting loss, crater, microfoam, and instability often need different solutions even inside the same formula.<\/li>\n<li><strong>Check compatibility at the intended dosage:<\/strong> the strongest additive can still be the wrong commercial choice if it narrows the process window too much.<\/li>\n<li><strong>Review the stage of use:<\/strong> some products are most useful during grind, while others matter more during let-down, filling, or final application.<\/li>\n<li><strong>Balance cure or film quality with defect control:<\/strong> the right additive fixes the problem without sacrificing adhesion, gloss, or appearance.<\/li>\n<\/ul>\n<h3>Riferimenti prodotto consigliati<\/h3>\n<ul>\n<li><strong><a href=\"https:\/\/longchangchemical.com\/it\/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\/it\/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\/it\/product\/chlumiaf-3037\/\">CHLUMIAF 3037<\/a>:<\/strong> A stronger process-defoaming option when persistent foam survives harsher conditions.<\/li>\n<li><strong><a href=\"https:\/\/longchangchemical.com\/it\/product\/chlumiwe-3280\/\">CHLUMIWE 3280<\/a>:<\/strong> A strong wetting-agent reference for inks, coatings, and difficult substrate wetting.<\/li>\n<\/ul>\n<h3>FAQ per acquirenti e formulatori<\/h3>\n<p><strong>Why does an additive that looks powerful in a beaker sometimes fail in production?<\/strong><br \/>Because shear, temperature, substrate, and the full formula can all change the way the additive performs under real process conditions.<\/p>\n<p><strong>Should the most aggressive additive always be preferred?<\/strong><br \/>Not usually.
