Transfer Coating
EB technology can be used very effectively for transfer coating. Advantages include the
elimination of thermal dryers needed for solvent and water based adhesives, and instant
curing to give a permanent bond. EB transfer coating is also a cool process which allows
transfer to heat sensitive substrates. An inherent advantage of any transfer coating
process is the highly uniform surface that is defined by casting the coating on the original
carrier film. Applications include the transfer of metallized layers as well as a variety of
other specialty coatings and decorative layers.
A variation of EB transfer coating involves pattern printing of the adhesive. Upon curing
though the film the coating is transferred in the pattern defined by the printed adhesive.
This process eliminates the use of expensive hot stamping dies.
