Metallized composite structure and a method of preparing same

摘要

A metallic laminate is prepared by coating a major surface of a polymeric film with a release agent having the capacity to effect a weak releasable bond from the surface of the polymeric film and a strong non-releasable bond with a surface of a stratum of metal which has been freshly vapor deposited, precipitating a thin coherent stratum of metal on the coated surface of the polymeric film by vapor deposition, applying a layer of standard laminating adhesive to the exposed stratum of metal and bonding the stratum of metal to a non-metallic substrate by standard laminating techniques using a liquid lacquer that, after application on the carrier, has a contact angle of 0 DEG to the carrier surface. The resulting metallized vapor coated composite structure has a reflectivity of at least 85%, a heat emission of about 8% of the Stefan Boltzmann constant at 25 DEG C., a mirror reflectivity of at least 4, and dead fold properties that are the same as those of the substrate.
