The researchers synthesized a polyurethane prepolymer by reacting LDI with a bio-based polyol derived from castor oil. This prepolymer was then cured using an environmentally friendly crosslinker to produce a coating with excellent mechanical properties and enhanced chemical resistance. The study highlights the potential of LDI as a sustainable alternative to conventional isocyanates in coating applications, offering reduced toxicity and improved environmental compatibility.<\/p><figure class=\"wp-block-embed\"><div class=\"wp-block-embed__wrapper\">\nhttps:\/\/doi.org\/10.1016\/j.porgcoat.2024.108553\n<\/div><\/figure><p class=\"wp-block-paragraph\"><strong>Raw materials availability:<\/strong><\/p><p class=\"wp-block-paragraph\">L-<a href=\"https:\/\/4medchem.com\/product\/lysine-diisocyanate-cas-45172-15-4\/\" data-type=\"link\" data-id=\"https:\/\/4medchem.com\/product\/lysine-diisocyanate-cas-45172-15-4\/\">Lysine diisocyanate\u00a0<\/a><\/p><p class=\"wp-block-paragraph\"><a href=\"https:\/\/4medchem.com\/product\/cas-2453-03-4-trimethylene-carbonate-13-dioxan-2-one\/\">Trimethylene carbonate<\/a><\/p>","protected":false},"excerpt":{"rendered":"<p>The article published in&nbsp;Progress in Organic Coati [&hellip;]<\/p>\n<a class=\"read-more\" href=\"https:\/\/4medchem.cn\/en\/waterborne-polyurethane-synthesized-for-leather-with-excellent-wear-and-hydrolysis-resistance-enabled-by-bio-based-polytrimethylene-carbonate-and-l-lysine-diisocyanate\/\">Read More \u2192<\/a>","protected":false},"author":2,"featured_media":0,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[1],"tags":[],"class_list":["post-1444","post","type-post","status-publish","format-standard","hentry","category-uncategorized"],"_links":{"self":[{"href":"https:\/\/4medchem.cn\/en\/wp-json\/wp\/v2\/posts\/1444","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/4medchem.cn\/en\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/4medchem.cn\/en\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/4medchem.cn\/en\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/4medchem.cn\/en\/wp-json\/wp\/v2\/comments?post=1444"}],"version-history":[{"count":3,"href":"https:\/\/4medchem.cn\/en\/wp-json\/wp\/v2\/posts\/1444\/revisions"}],"predecessor-version":[{"id":2366,"href":"https:\/\/4medchem.cn\/en\/wp-json\/wp\/v2\/posts\/1444\/revisions\/2366"}],"wp:attachment":[{"href":"https:\/\/4medchem.cn\/en\/wp-json\/wp\/v2\/media?parent=1444"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/4medchem.cn\/en\/wp-json\/wp\/v2\/categories?post=1444"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/4medchem.cn\/en\/wp-json\/wp\/v2\/tags?post=1444"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
