Desmomelt® - thermoactivable polyurethane based raw materials for hotmelts


Unlike conventional thermoplastic hotmelts, Desmomelt® based hotmelts shows additional advantages after thermoactivation. These hotmelts show additional advantages in the finished product. Our Desmomelt® VP KA 8702 is a linear, thermo-activatable polyurethane powder based on a polyester polyol and an aromatic diisocyanate. It exhibits these properties:
    • Solvent-free
    • 100% solids
    • Fast initial bond strength
    • Very high chemical resistance
    • Excellent adhesion on many substrates
    • Extreme high resistance against heat and cold
    • Low thermoactivation temperature for heat sensitive substrates
