Two-Part Polyurethane

Dura Pur™two-part polyurethane adhesives are used for structural bonding of plastics, fabrics, wood and metals. Two-part polyurethanes are packaged in two containers (an A part or polyol and a B part or isocyanate) that are mixed before they are applied either mechanically or by hand. The combining of the two chemicals starts the chemical reaction that cross-links the adhesive. Dura Pur™products can be applied at room temperature and do not need heat or moisture to cure. Handling strength and cure rates can range from a few seconds to 12 hours depending on the adhesive and environmental conditions.
