General Characterization
Aliphatic high-molecular-weight polyester-polyurethane adhesive raw material.
Desmomelt® U 320 is a solid raw material for the formulation of non-yellowing, thermally activated adhesives. Desmomelt® U 320 is particularly well suited for applications with low thermal activation temperatures as e.g. in automotive trim, textile, footwear and furniture applications. Desmomelt® U 320 can be used as a hotmelt applied as a filament, foil or powder, as well as a raw material for non-yellowing solvent-based contact and/or heat activated adhesives.
