Surface Preparation
The surface preparation recommended for VINYL-SHIELD™ 7342
is to include removal of all oil, grease, dirt, dust, mill scale, rust,
paint, oxide, corrosion product, and other foreign matters. This
can be accomplished with hydroblasting, grit sweeping and with
a variety of mechanical descaling tools. For steel, the minimum
standard is Steel Structures Painting Council Standard SSPC-SP6.The
recommended surface preparation is SSPC-SP-10. For galvanized
steel and aluminum, the minimum standard is SSPC-SP-1 (solvent
cleaning).
Mixing and Thinning
VINYL-SHIELD™ 7342, is a two component product supplied in a 1
US gallon kit which contains the proper ratio of ingredients. The entire
content of each container must be mixed together. Power mix the
base portion first to obtain a smooth, homogeneous product.
After mixing the base portion (VINYL-SHIELD™ 7342 "Part A") for
a 5 to 10 minutes, making sure pigment is fully incorporated slowly
add component "B" (acid catalyst Vinyl-Shield™ GS 7343C) with
continued agitation. After the component "B" add is complete,
continue to mix slowly until both components are thoroughly mixed.
Thinning is not required. The pot life of the mixd material is 6 hours
at 77ºF (25ºC). Higher temperatures will reduce the pot life of the
product; lower temperatures will increase it.
Application Conditions
Industry standards are for the substrate temperatures to be above
10º C of the dew point. Condensation due to substrate temperatures
below the dew point can cause fl ash rusting on prepared steel and
interfere with proper adhesion to the substrate.
Special application techniques may be required above or below
normal application conditions.

Application
VINYL-SHIELD™ 7342 must be spray applied. Care should be
taken that proper and uniform, thin, film thicknesses are obtained.
For HVLP applications, please refer and comply with equipment
supplier's recommendations.

Curing Schedule
These times are based on a 2.0-3.0 mil (50-75 micron) dry film
thickness. Higher film thickness, insufficient ventilation or cooler
temperatures will require longer cure times and could result in
solvent entrapment and premature failure of the film. Consult
technical services for recommendations and test results. If the
maximum recoat time has been exceeded, the surface must
be sanded or prepared with a brush off blast SSPC-SP-7 prior to
the application of additional coats. Vinyl-Shield™ 7342 applied
below 40ºF (4ºC) may temporarily soften for several hours, after
temperatures rise to 60ºF (16ºC). This is a normal condition and will
not influence performance.
