Desmodur® HL EA is an aromatic/aliphatic polyisocyanate based on toluylene diisocyanate/ hexamethylene diisocyanate. It has a viscosity at 23°C of 1,100 ± 600 mPa·s, a flash point of -2°C, and a density at 20°C of approx. 1.12g/ml. This product can be used in combination with various Desmophen® grades or other suitable substances containing hydroxyl groups to formulate clear or pigmented, two-component polyurethane coatings characterized by rapid drying and good lightfastness. The rapid initial drying and early sandability are of particular advantage when formulating wood coatings. With just a few coats, high-bodied clear or pigmented finishes can be easily achieved. Desmodur® HL EA can also be used to formulate high-quality coatings for paper and foils.
