The trimerization of HDI can be catalyzed by a number of Lewis bases of inorganic and organic salts as well as other materials. The ratio of trimer to oligomer is used to adjust the molecular weight and viscosity. The advantage of a cyclic trimer is that a six-membered ring is chemically and thermally very stable. Accordingly, trimers are made from not only HDI, but IPDI and TDI as well. TMXDI-based polyisocyanates are used in waterborne coatings and adhesives, whereas IPDI-based uretdiones are often used in TS powder coatings. The four-member uretdione ring is not as stable as a six-membered ring and thus various substitutions on the uretdione can be used to alter the reactivity and stability.<\/p>\n<h2><a href=\"https:\/\/www.ulprospector.com\/en\/na\/Coatings\/Product\/search?k=%22Isocyanate+terminated+prepolymers%22&amp;st=31&amp;so=k_0&amp;sl=153457945&amp;utm_source=Knowledge+Center&amp;utm_medium=article&amp;utm_campaign=Polyisocyanates&amp;utm_term=2023PC&amp;utm_content=Lewarchik\" target=\"_blank\" rel=\"noopener\">Isocyanate-terminated prepolymers<\/a><\/h2>\n<p>Isocyanate-terminated prepolymers or hydroxy-terminated polyurethanes can be synthesized by using either an excess stoichiometric amount of diol with diisocyanate to form a hydroxy-terminated polyol or conversely using an excess amount of diisocyanate to form an isocyanate-terminated prepolymer and then removing the excess diol or isocyanate respectively.<\/p>\n<p>Single-component thermosetting polyurethanes can be formulated by using <a href=\"https:\/\/www.ulprospector.com\/en\/na\/Coatings\/Product\/search?k=Blocked+Isocyanates&amp;sug=1&amp;st=31&amp;utm_source=Knowledge+Center&amp;utm_medium=article&amp;utm_campaign=Polyisocyanates&amp;utm_term=2023PC&amp;utm_content=Lewarchik\" target=\"_blank\" rel=\"noopener\">blocked isocyanates<\/a>.
