Vacuum Metallizing<br />
Vacuum metallization involves the evaporation, and<br />
subsequent condensation, of a metal onto a substrate<br />
in a vacuum chamber. The metal used in most industrial<br />
applications is aluminum. When the end use requirement<br />
is primarily decorative, the substrate is usually processed<br />
with two organic coatings called the basecoat and the<br />
topcoat with the metal layer deposited in between. The<br />
primary function of the basecoat is to produce a smooth<br />
surface on molded plastic parts so that the metal layer<br />
will have maximum luster. A secondary function of the<br />
basecoat is to maximize adhesion of the metal layer to<br />
the substrate. On substrates that tend to outgas in a<br />
vacuum, the basecoat also provides a barrier layer. The<br />
function of the topcoat is to protect the metal layer from<br />
physical, oxidative, or chemical deterioration.<br />
Basecoats that are compatible with Amodel resins<br />
include #VB-4315, #VB-4774, and #VB-4836-1 from<br />
Pearl Paints, http://www.pearlpaints.com. Topcoats that<br />
are compatible with Amodel resin include #VT 4316-2,<br />
also from Pearl Paints.<br />
Because of the need to vaporize the metal materials<br />
during this process, an elevated temperature may be<br />
expected in the vacuum chamber. The rate at which<br />
parts may be coated is controlled by the thermal<br />
characteristics of the substrate material. For this reason,<br />
Amodel resin, with its high heat deflection temperature,<br />
is an excellent candidate material when metallization<br />
is required as comparatively rapid cycle times may<br />
be obtained.<br />
