DESMODUR ULTRA N 31100

DESMODUR ULTRA N 31100 is an aliphatic polyisocyanate based on hexamethylene diisocyanate. It has a low viscosity of around 450 mPa.s at 25°C making it well suited for formulating high-solids coatings. As the hardener component, DESMODUR ULTRA N 31100 provides lightfast and weather-stable properties to coating systems. Its compatibility with various Desmodur grades and other hydroxyfunctional polymers allows for a wide range of formulations. Coatings made using DESMODUR ULTRA N 31100 as the curing agent exhibit excellent durability suited for general industrial, automotive refinishing and transportation applications. The product's lightfastness and weathering resistance translates to long-lasting protective coatings for infrastructure and assets.
