The invention is directed to a method for laminating a suspended particle
device (SPD) film which comprises forming a suspended particle device
film; positioning the suspended particle device film within an
unlaminated stack of components for forming a laminated suspended
particle device film, wherein the stack comprises at least one hot melt
adhesive sheet or film contacting an outer surface of the suspended
particle device film; subjecting the unlaminated stack to at least a
partial vacuum, preheating the unlaminated stack of components under the
vacuum for a time and at a temperature selected to permit at least
partial degassing of the stack and applying a sufficient net pressure to
the stack at a sufficient temperature and for a sufficient time to
produce a laminated suspended particle device film from the unlaminated
stack.
