Product Description
Hi-Temp 1027 is a coating specifically formulated
to prevent corrosion of carbon steel under
thermal insulation. The coating is a high solid system
which can be applied to a dry film thickness of 10-18
mils.* and has a VOC content of 3.5 lb./gal. 1027 has
the ability to withstand thermal cyclic conditions to
1200°F (649°C), with peaks to 1400°F (753°C). The
coating is resistant to severe cyclic tests; dry heat of
1000°F (538°C), immersion in boiling water, dry heat
of 1000°F (538°C), and continously repeated.
*While applying to hot steel, 1027 has the ability to
be applied to a dft. of 30 mils. when the maximum heat
resistance needed is only 500°F (260°C).
*While applying to hot steel, 1027 has the ability to
be applied to a dft. of 45 mils. when a maximum heat
resistance needed is only 400°F (208°C).
Hi-Temp 1027 can be applied to ambient steel or
directly to hot operating equipment having a metal
temperature of 500°F (260°C) during application.
Owners of equipment can: 1) strip insulation 2) prepare
the surface 3) apply the coating and 4) reinsulate, without
having to interrupt their business. Hi-Temp 1027
allows the repair and maintenance of critical equipment,
which cannot be shut down, and yet is experiencing
corrosion under insulation.
Hi-Temp 1027 is UV resistant and has an open
recoat window whether it has been applied to ambient
or hot steel.
The high film build capability of the 1027, whether
applied to ambient or hot metal, allows one to cover the
peaks and valleys of badly pitted steel under insulation;
as well as properly protect difficult to coat areas such
as flanges and bolts. The ability to be applied at film
thickness higher than recommended is important when
confined to tight spaces where it is difficult to control
the dry film thickness during application.

Surface Preparation Carbon 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 1.5-
2.5 mils., (38-63 microns), in depth. If "Commercial Blast" is not possible an SSPC-SP 11 "Power Tool" is approved.
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).
* Do not exceed maximum dry film thickness recommendations.

Hot steel application from 150-300°F (61-122°C):
Allow 20 minutes in between coats.
Hot steel during application from 300-500°F (122-260°C):
Allow 15 minutes in between coats.

Systems 3): Maximum temperature resistance needed is
only 500°F (260°C) and 400°F (208°C) respectively.
For both temperatures follow the standard specification for
ambient or hot steel application.
Maximum dry film thickness while applying directly to hot
steel up to 500°F (260°C) is 24.0-30.0 mils. (600-750
microns) in 3 coats at 8.0-10.0 (200-250 microns) per coat.*
Maximum dry film thickness while applying directly to hot
steel up to 400°F (208°C) is 40.0-45.0 mils. (1000-1125
microns) in 4 coats at 9.0-11.0 mils. (225-275 microns) per
coat.*
*When applying such thicknesses per coat directly to hot
steel, it is important not to apply all the material at once in
one pass but to apply it in multiple thin passes.
When applying 20-30 mils. dft. in 3 coats allow 30-45 minutes
between coats.
When applying 30-45 mils. dft. in 4 coats allow 1 hour
between coats.
Application Instructions to Hot Steel
1. IMPORTANT! It is essential to apply thin coats of the
Hi-Temp 1027 during an application to hot steel. This aids
in allowing the solvent to escape the coating without
leaving pinholes behind. This application is similar to
mist coating.
2. Flush equipment with Hi-Temp #5 Thinner
before using equipment.
3. Hi-Temp 1027 is normally not thinned. If the
situation warrants thinning, use only Hi-Temp #5
Thinner.
4. Hi-Temp #5 Thinner is specifically formulated for
Hi-Temp 1027. It is a slow evaporating solvent
allowing for good film integrity as the coating is
being applied to hot operating equipment.
5. WARNING! Do not thin Hi-Temp 1027 with any other
solvent. A fire hazard could occur if using a different
solvent system. Dry spray and poor film characteristics may occur as well.
6. Do not apply a heavy coat to a hot surface or
blistering will occur. If this happens, immediately take
a brush, (use wood-handled brushes with China bristles
only. Do not use brush with synthetic bristles), and
brush out the blister before it sets.
7. Application to hot surfaces tends to promote dry spray.
8. To avoid dry spray, apply coatings without reaching.
Equipment
Conventional or airless spray is recommended. For conventional
spray use a DeVilbiss MBC-510, (or equal),
gun with an "E" fluid tip and 704 air cap (or equal). For
airless spray use a Graco 205-591, 208-663, (or equal),
gun with fluid tip of 163-610, 163-315 and a Graco
Bulldog Pump at 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 and during application. Mix materials until
uniform in consistency.
Thinning
Thinning is not normally needed. If a condition warrants
thinning, thin only with Hi-Temp #5 Thinner. Thin
according to local air regulations.
Clean-up
Use Hi-Temp #5 Thinner.
