Product Description
Hi-Temp 500V Series has a VOC content 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 500V 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. 500V
Series air dries rapidly, is an ambient temperature cure
coating system and does not require heat cure. It is able
to withstand severe thermal cycling up to 850°F
(442°C). It is a user friendly system with excellent
brush and roller characteristics. Hi-Temp 500V Series
has excellent weathering and corrosion resistance
when applied over properly primed surfaces.
- 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) 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 500V Series at 2.0-2.5 mils. dft.
Prior to a full topcoat application, apply 500V Series
to a small area and test for adhesion.
4) 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 600
ZN or 1150 HB (consult an HTC technical representative
for the selection) 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 500V Series at 2.0-2.5 mils. dft
over the entire unit. Prior to the full topcoat application,
apply the 500V 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.
