Product Description
Hi-Temp 500VS Series has a VOC of 3.5 lb./gal. It
is a silicone acrylic system formulated with a high percentage
of silicone resin, a thermally stable acrylic
resin and inorganic pigments. This combination allows the 500VS Series to
have superior color stability to 500°F (260°C)* as compared
to most generic silicone acrylic topcoats, which
tend to discolor at elevated temperatures. It is available
in both standard and custom colors. 500VS Series is an ambient temperature cure coating
system and does not require heat cure. It is able to
withstand severe thermal cycling up to 600°F (315°C).
It is a user friendly system with superior brush and
roller characteristics. Hi-Temp 500VS Series has
excellent weathering and corrosion resistance when
applied over properly primed surfaces.
Hi-Temp 500VS is specifically formulated as an
ambient topcoat for Hi-Temp 1027 Primer.
- Black and aluminum pigmented coatings have color stability to 850°F (454.4°C)
- Radiant energy can sometimes cause a temporary change in the appearance of heat resistant coatings.
- A delta change of 5+ units may occur when light colored topcoats are exposed to continuous maximum temperatures.

Surface Preparation
1) New Surfaces: Steel
Coated surfaces must be dry and free of weld splatter,
oil, dirt, grease, and all other contaminates. Round off
all rough welds and sharp edges. Abrasive blast to a SSPC-SP
6 "Commercial Blast". Blast profile should be 1.0-1.5
mils., (25-38 microns), in depth.
2) Previously Painted Surfaces: Poor Condition
Old coating shows evidence of cracking, fracturing,
delamination, and/or corrosion. Surface preparation guidelines
for new steel should be followed.
3) Rusty Surfaces
Surfaces with much corrosion present. Guideline for
new steel should try to be followed. If abrasive blast is not
possible, prepare the surface by an SSPC-SP 11 "Power
Tool". If this is unattainable, prepare the surface by an
SSPC-SP 2 "Hand Tool Cleaning." Apply one prime coat of
Hi-Temp 1027 DTR. Application over tightly adhering
rust is acceptable. Topcoat with one coat of Hi-
Temp 500VS. *Performance of system relative to surface
preparation accomplished.
4) Previously Painted Surfaces: Good Condition
Old coating is intact and there is no evidence of
cracking, fracturing, and/or delamination. Pressure wash
surface to remove all oil, grease, and contaminates and
apply one coat of 500VS Series at 2.0-2.5 mils. dft.
Prior to a full topcoat application, apply 500VS Series
to a small area and test for adhesion.
5) Previously Painted Surfaces: Good Condition,
some spotted corrosion
Old coating is intact, there is no evidence of
cracking, fracturing, and/or delamination. However,
there are small areas of corrosion which amount to
less than 10% of the area to be coated. Spot prepare
the areas of corrosion by an SSPC-SP 6 "Commercial
Blast". Blast profile should be 1.0-1.5 mils. in depth.
If abrasive blasting is not permitted, prepare the area
by a power tool cleaning accordance to an SSPC-SP
11. Apply one prime coat of either Hi-Temp 1027 to these areas. Once these areas
are primed and dry, power wash the entire structure,
removing all oil, grease, and other contaminates.
Apply one coat of 500VS Series at 2.0-2.5 mils. dft
over the entire unit. Prior to the full topcoat application,
apply the 500VS Series to a small area and test
for adhesion.
Application Instructions
Surface temperature must be a minimum of 5°F (3°C),
above the dew point. Do not apply to steel temperatures
below 50°F (10°C).

Equipment
Conventional or airless spray is recommended. For conventional
spray use a DeVilbiss MBC-510, (or equal),
gun with an AV115-FZ (.0425") fluid tip and a 704 air
cap. For airless spray use a Graco 205-591, 208-663, (or
equal), gun with a fluid tip of 163-614, 163-616 and
Graco Bulldog Pump 30:1.
Adjust pressure as needed. Hold gun 10"-12" from the
surface at right angles. Lap each pass 50%. When brushing
and rolling, use only quality brushes and rollers.
Mixing
Use mechanical agitation for mixing. Mix materials until
uniform in consistency.
Thinning
Thinning is not normally needed. If a condition warrants
thinning, thin only with Hi-Temp #10 Thinner. Thin
according to local air regulations.
Clean-up
Use Hi-Temp #10 Thinner.
