Polyurethane Structural Adhesives, by reacting an aliphatic diisocyanate with an aliphatic diamine or dio1.. These materials soon found commercial uses and were marketed under the trade names of Irgamid U, for plastics, and Perlon U for synthetic fibers and bristles. Very soon after this, it was discovered that isocyanates could be
