Solid, non-melting polyurethanes having a glass transition temperature of at least 40° C. and free isocyanate groups are self-bonding materials that are useful in a variety of adhesive and molding operations. Under conditions of heat and moisture, these polyurethanes will self-bond. The polyurethanes can be used as adhesive coatings, which are solid and non-tacky and thus can be transported and stored easily under ambient conditions. These polyurethane adhesives are especially useful in applications in which, due to the location and/or orientation of the substrates, liquid or melting materials cannot be applied easily or will run off the substrates.

A method of producing a vehicle includes determining the performance of aged adhesive coupons, which are subject to a worst-case scenario of manufacturing, aging, and stress testing. Virtual vehicle components are modeled using the performance of the aged adhesive coupons. The virtual vehicle components are then subjected to virtual mechanical forces to determine their virtual performance, which is then validated against the performance of identical real-life aged vehicle components subjected to identical mechanical forces. A virtual vehicle is modeled using the validated virtual vehicle components. The virtual performance of the virtual vehicle when subject to a virtual crash test is then compared against a predetermined standard, and the design of the virtual vehicle is considered feasible if its performance exceeds the predetermined standard. A vehicle is manufactured according to the feasible design of the virtual vehicle.
