Risposta rapida:<\/strong> buyers choosing additives for screen inks<\/strong> usually get a faster shortlist when they separate three different problems early: poor substrate wetting<\/strong>, weak print-face leveling or slip balance<\/strong>e persistent foam or entrained air<\/strong>. In Longchang’s CHLUMICRYL\u00ae branch, CHLUMIWE\u00ae 3280<\/a> is the cleaner first route when the screen ink needs a direct wetting solution. CHLUMILE\u00ae 3432<\/a> deserves earlier review when the real pressure is smoother laydown, better slip, and less anti-blocking trouble on the printed face. CHLUMIAF\u00ae 3062<\/a> moves up when print consistency is being limited by foam, microbubbles, or air-release instability.<\/p>\n

This page is intentionally narrower than the broader CHLUMICRYL\u00ae Additivi per vernici e inchiostri<\/a> overview and different from the already-live function pages for additivi bagnanti<\/a>, additivi livellanti<\/a>e antischiuma<\/a>. The buyer question here is more application-specific: which additive route makes sense when the print line is screen printing and the real commercial pressure is coverage, smooth laydown, blocking behavior, or process stability?<\/p>\n

Why screen inks deserve a separate additive-selection page<\/h2>\n

Screen-printing inks are not just another generic printing-ink case. Buyers often have to keep bagnatura del substrato<\/strong>, printed-face smoothness<\/strong>e line stability<\/strong> in balance while working with a heavier deposited ink film than many other printing methods. That usually means the first shortlist should not start from a broad \u201cink additive\u201d label. It should start from the actual defect or processing bottleneck.<\/p>\n

General industry framing around printing-ink additives also separates wetting behavior, slip or rub behavior, anti-blocking, and defoaming as different jobs rather than one interchangeable additive function. That broader framing helps explain why a dedicated screen-ink page is commercially useful here. The product-level claims below stay tied to Longchang-supported product pages and company-controlled application notes.<\/p>\n

Quick shortlist: when CHLUMIWE\u00ae 3280, CHLUMILE\u00ae 3432, or CHLUMIAF\u00ae 3062 usually makes sense<\/h2>\n\n\n\n\n\n\n\n
Prodotto<\/th>\nBest first fit in screen inks<\/th>\nPerch\u00e9 gli acquirenti lo selezionano<\/th>\nPunto di osservazione principale<\/th>\n<\/tr>\n<\/thead>\n
CHLUMIWE\u00ae 3280<\/td>\nSubstrate wetting when the ink is not spreading or covering cleanly<\/td>\nLongchang directly positions it as a silicone wetting agent and screen printing ink wetting agent<\/strong>, with low surface tension and a recommended dosage of 0.2% to 3.0%.<\/td>\nUse it when wetting is the first bottleneck, not as a substitute for slip or foam-control work.<\/td>\n<\/tr>\n
CHLUMILE\u00ae 3432<\/td>\nPrint-face leveling, smoothness, slip, anti-adhesion, and anti-blocking<\/td>\nLongchang directly supports 3432 for printing-ink applications and describes improved wetting and leveling, ultra-smooth effect, low stable foam, compatibility, anti-adhesion, anti-blocking, and slip.<\/td>\nChoose it when the problem sits on the printed face rather than in process foam alone.<\/td>\n<\/tr>\n
CHLUMIAF\u00ae 3062<\/td>\nFoam-control and air-release stability in coatings, inks, and UV inks<\/td>\nLongchang directly supports 3062 as a printing-ink defoamer with recommended printing-ink dosage of 0.1% to 0.5%, broad system applicability, and balanced defoaming plus foam inhibition.<\/td>\nIt is the stronger route when foam is the real defect, not when the first problem is substrate wetting or surface slip.<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n

When CHLUMIWE\u00ae 3280 is the better fit<\/h2>\n

CHLUMIWE\u00ae 3280<\/a> should move up first when the screen-ink program is being limited by bagnatura del substrato<\/strong> instead of by surface feel or foam alone. Longchang directly titles it as a silicone wetting agent, screen printing ink wetting agent<\/strong>. The current product page also supports a recommended dosage of 0.2% to 3.0%<\/strong>, polisilossano modificato con polieteri<\/strong> chemistry, and surface tension less than or equal to 25 mN\/m<\/strong>.<\/p>\n

That makes 3280 the cleaner first route when:<\/p>\n
