Desmodur® HL BA

Covestro (formerly Bayer MaterialScience) 科思创

Desmodur® HL BA is an aromatic/aliphatic polyisocyanate based on toluylene diisocyanate/ hexamethylene diisocyanate. It can be used with Desmophen® grades or other substances containing hydroxyl groups to make clear or pigmented, two-pack polyurethane coatings with 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. This product has a viscosity at 23°C of 2,200 ± 1,000 mPa·s, a flash point of +28°C, and a density at 20°C of approximately 1.13g/ml.
