Desmomelt® U aliphatic polyurethane powders for adhesives
Desmomelt® U is a new class of aliphatic, non-yellowing polyurethane (PU) adhesive raw materials combining the high molecular weight and bond strength of solvent- or waterborne PU adhesives in a 100% solid form. Supplied as a powder, it can be processed into filament or foil for adhesive hotmelt application including via digital printing.
The Desmomelt® U range of thermoplastic resins is designed for adhesive applications that demand a high initial and final bond strength coupled with non-yellowing properties. This thermoplastic adhesive raw material is aliphatic, and Desmomelt® U powders can be supplied in a wide range of crystallization rates and molecular weights.
Desmomelt® U powders are well-suited for heat-activated bonding processes at low temperatures.
The non-yellowing material offers outstanding adhesion to many synthetic and natural substrates, and can be blended to further optimize its performance for your application.
These aliphatic adhesive powders can also be compounded and processed into fine powders, filaments and foils for hotmelt adhesive application With Desmomelt U the adhesive application can be automated with digital printing, which enables precise application of hotmelt adhesive even on complex geometries. Desmomelt® U powders can also be used directly as raw materials for solvent-borne adhesives, and customized in high performance formulations to match the needs of the footwear, textile, electronics, automotive interior and furniture markets.
By uniting the bond strength of solvent- and water-borne PU adhesives with the speed and processability of hotmelts, Desmomelt® U adhesive powders simplify a wide range of automated applications including digital printing and additive manufacturing.
Featured Products
Aliphatic high-molecular-weight polyester-polyurethane adhesive raw material.
Desmomelt® U 230 is a solid raw material for the formulation of non-yellowing, thermally activated adhesives. Desmomelt® U 230 is particularly well suited for applications with low thermal activation temperatures as e.g. in automotive trim, textile, footwear and furniture applications. Desmomelt® U 230 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.
