摘要 |
A liquid, solvent-free or low solvent hardenable polyurethane-modified bitumen composition is described, which is based on a bitumen modified with a polyurethane prepolymer. The compatability between bitumen and polyurethane prepolymer is achieved by a plasticizer system comprising a primary and a secondary plasticizer. The inventive composition is particularly suitable as an adhesive, sealant, foam material or coating compound.
