Description
|
|
VB-4774 has been
specifically formulated for use on
Interior Automotive Lighting
applications where low curing and high
intensity in-service temperatures are
required. Among it’s
attributes, VB-4774 offers outstanding
plate adhesion, exceptional depth of
field, brilliance and above average thin
film distortion characteristics.
VB-4774 adheres
equally well to such substrates as Zenoy, Nylon, Polycarbonate, and
GTX. Due to its high level of solids and
outstanding flow characteristics,
VB-4774 aids in the coverage of many
substrate surface imperfections, making
it ideal for use in a wide variety of
applications.
