Desmomelt® U 320 M
Aliphatic high-molecular-weight polyester polyurethane. Desmomelt® U 320 M is a fine powder for the production of non-yellowing, thermally activated hot melt adhesives. Desmomelt® U 320 M is well suited for applications with low thermal activation temperatures, such as automotive, textile, footwear and furniture applications. With Desmomelt® U 320 M, fast and environmentally friendly lamination processes can be realized, e.g. by powder scattering. Desmomelt® U 320 M has very good adhesion to textile substrates and to a variety of other materials such as soft PVC, rubber, wood, polyurethane elastomers.
