You are working for a trucking company and want to adhesively bond high density polyethylene panels into the floor of your semi-trailer. The interior of the truck will periodically be exposedto 120⁰C pressurized steam for cleaning and sterilization, The panels are not allowed to lose their shape during these washing sand must not debond while heavy cargo slides across the surface.The of high density polyethyleneis110°C.How can you accomplish this task if cost is no object?
