\u5feb\u901f\u56de\u7b54\uff1a<\/strong> buyers should not treat CHLUMIAG\u00ae 5005<\/a>, CHLUMIAG\u00ae 5005-60<\/a>\uff0c \u548c CHLUMIFE\u00ae 3388<\/a> as interchangeable PU-leather additives. 5005<\/strong> should move up first when the project needs a more deliberate permanent hand-feel plus stain-resistance<\/strong> route in solvent-side or oil-based systems. 5005-60<\/strong> becomes more relevant when the team wants a reactive hydroxyl-system route<\/strong> that is also positioned as an anti-graffiti or baking-paint hand-feel additive. 3388<\/strong> deserves earlier review when the finish target is a delicate dry touch for PU leather<\/strong> and the buyer also cares about not damaging gloss or transparency in the gloss layer<\/strong>.<\/p>\n

This page is not another broad anti-graffiti overview. It is a narrower buyer-comparison page for leather-finishing and specialty-coating teams who already know the project lives in the hand feel, stain resistance, easy cleanability, or release-performance<\/strong> zone and need a faster first shortlist.<\/p>\n

Why this comparison matters after the broader CHLUMICRYL\u00ae additive pages<\/h2>\n

\u9f99\u660c\u5df2\u7ecf\u6709\u4e86\u4e0a\u7ebf\u9875\u9762 CHLUMICRYL\u00ae \u6d82\u5c42\u548c\u6cb9\u58a8\u6dfb\u52a0\u5242<\/a>, \u9632\u6d82\u9e26\u6dfb\u52a0\u5242<\/a>, and several coating-surface decision pages. But buyers working on PU leather and specialty finishing often reach a tighter question after that: which product should be screened first when the surface has to feel better, resist staining more reliably, or release more cleanly without ruining the finish?<\/strong><\/p>\n

That is a different commercial decision from a broad function page. In practical finishing work, a route that gives durable stain resistance is not automatically the best route for soft dry touch, and a leather-specific feel modifier is not automatically the best benchmark when the project is really a reactive anti-graffiti or baking-paint problem.<\/p>\n

When CHLUMIAG\u00ae 5005 is the better first move<\/h2>\n

5005 belongs earlier when the buyer wants one route that can push hand feel<\/strong>, stain resistance<\/strong>\uff0c \u548c resin-side integration<\/strong> together instead of treating those as separate decisions. Longchang supports 5005 as a \u591a\u7ec4\u5206\u6539\u6027\u805a\u7845\u6c27\u70f7<\/strong> with three different commercial use windows:<\/p>\n
