Waterborne polyurethane synthesized for leather with excellent wear and hydrolysis resistance enabled by bio-based poly(trimethylene carbonate) and l-lysine diisocyanate
The article published in Progress in Organic Coatings (DOI: 10.1016/j.porgcoat.2024.107269) discusses the development of a novel bio-based coating utilizing lysine diisocyanate (LDI). 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.
