Until now, the necessary rigidity could only be achieved by means of additional metal reinforcement sheeting or struts, which considerably increase a vehicle's weight. Structural rigidity gluing in the side walls, bulkhead and floor area achieves the same results using only a few grams of adhesive - with no major modifications to the vehicle's design, shape or material characteristics. The additional sealing measures required until now for corrosion protection can be dispensed with in many cases. The adhesive system also proves advantageous in the case of an accident. Adhesives from polyurethane characterized by high ductile yield exercise a strong damping effect when transmitting the tension load peaks to the adhesive surfaces.
Glued components are thus far more durable than their constituent materials alone.
This means that some of the adhesive while still being soft was rinsed out in the cleansing bath prior to painting. This would result in a considerable degree of impurity, which in turn was detrimental to the paint application process. The adhesives now used, on the other hand, can be pre-gelled.
