|
|
Description
|
|
VB-4885 is a General
Purpose, low cost, Universal Vacuum Metallizing
Basecoat that has been designed for use
in Spray and Flow coating applications.
Ideally suited for use on such
substrates as Polystyrene, ABS, Acrylic,
Polycarbonate and Noryl Plastics,
VB-4885 offers fast cure times and
delivers outstanding hardness, gloss, clarity and
flow.
In addition, VB-4885
is offered at a high rate of solids,
allowing for a greater level of
reduction flexibility than may be found
in alternate coatings. VB-4885 also
performs equally well when used as a
Topcoat.
We suggest this Vacuum
Metallizing Basecoat for use in most
general purpose and decorative
Metallizing finishing applications. Not
recommended for un-primed and untreated
Polypropylene.
