Desmocoll® - Description
Desmocoll® hydroxyl functional polyester polyurethanes are designed for the formulation of solventborne adhesives. Supplied as small granules, Desmocoll® grades have good solubility in many organic solvents. They are differentiated with respect to their crystallization rates, heat-resistance properties, adhesion to specific substrates and solution viscosities. They are formulated for a range of heat-activation temperatures and bonding and lamination applications in the automotive, footwear, furniture and packaging industries.

Thermo-activated adhesives formulated with these offer several advantages:
• High initial and final bond strengths
• Good heat resistance and long-term durability, particularly when used in combination with Desmodur® R isocyanate crosslinkers
• Materials with applied, dried adhesive can be stored or transported for later bonding
Desmocoll® 400 and 500 series products offer excellent adhesion to PVC substrates and have high resistance to the most commonly used PVC plasticizers.
Although most Desmocoll®-based adhesives are heat-activated, formulations are also available for systems that require no activation.
