screen photoinitiators, the most useful decision frame is usually cure quality plus application fit: which package cures reliably, keeps appearance acceptable, and still works under the lamp, film thickness, and substrate conditions of the actual process.<\/p>\n<ul>\n<li><strong>Match the package to the lamp first:<\/strong> mercury lamps, UV LEDs, and visible-light systems can rank the same photoinitiators very differently.<\/li>\n<li><strong>Check depth cure and surface cure separately:<\/strong> a film that feels dry on top can still be weak underneath.<\/li>\n<li><strong>Balance yellowing with reactivity:<\/strong> the strongest deep-cure route is not always the best commercial choice if color or migration risk becomes unacceptable.<\/li>\n<li><strong>Use the final formula as the benchmark:<\/strong> pigment load, monomer package, and film thickness can all change the apparent ranking of the same initiator.<\/li>\n<\/ul>\n<h3>Recommended product

photoinitiator packages so common?<\/strong><br \/>Because one product may control yellowing or lamp fit well while another improves cure depth or line-speed performance, so the full package is often stronger than any single grade.<\/p>\n<p><strong>Should incomplete cure always be solved by adding more initiator?<\/strong><br \/>Not automatically. The real limitation may be the lamp, film thickness, pigment shading, or the rest of the reactive system rather than simple under-dosage.<\/p>\n<p><!-- lc-commercial-end --><\/p>\n<h2><strong><b>\u7acb\u5373\u8054\u7cfb\u6211\u4eec\uff01<\/b><\/strong><\/h2>\n<h4><strong><b>\u5982\u679c <\/b><\/strong><strong><b>\u5982\u679c\u60a8\u9700\u8981\u4ef7\u683c\u6216 COA\u3001MSDS \u6216 TDS\uff0c\u8bf7 <\/b><\/strong><strong><b>\u8bf7\u586b\u5199\u4e0b\u8868\u5e76\u6ce8\u660e\uff0c\u6211\u4eec\u901a\u5e38\u4f1a\u5728 24 \u5c0f\u65f6\u5185\u4e0e\u60a8\u8054\u7cfb\u3002\u60a8\u4e5f\u53ef\u4ee5\u7ed9\u6211\u53d1\u7535\u5b50\u90ae\u4ef6 <span style=\"color: #0000ff;\"><a style=\"color: #0000ff;\" href=\"mailto:info@longchangchemical.com\">info@longchangchemical.com<\/a><\/span> \u8bf7\u5728\u5de5\u4f5c\u65f6\u95f4\uff08UTC+8 \u5468\u4e00\u81f3\u5468\u516d\uff0c\u4e0a\u5348 8:30 \u81f3\u4e0b\u5348 6:00\uff09\u6216\u4f7f\u7528\u7f51\u7ad9\u5373\u65f6\u804a\u5929\u5de5\u5177\u83b7\u5f97\u53ca\u65f6\u56de\u590d\u3002<\/b><\/strong><\/h4>","protected":false},"excerpt":{"rendered":"<p>In the curing process of UV adhesive there is a gelation process.
