Product Description
Hi-Temp 600 ZN HA Primer is a modified silicone zinc
primer formulated to withstand severe thermal cycling
to 600°F (315°C). 600 ZN HA Primer was
designed specifically for direct application to hot
operating equipment. The temperature of the metal
can be as hot as 300°F (156°C). It has excellent
weathering and corrosion resistance. Hi-Temp 600 ZN
HA primer is an ideal heat resistant primer with the
ability to be applied to hot operating equipment thereby
eliminating costly shutdown periods.

Surface Preparation
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. If abrasive blasting is not permitted, prepare the area by a
power tool cleaning according to SSPC-SP 11.
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).
Systems: Un-insulated Steel*

Application Instructions to Hot Steel
1. IMPORTANT! It is essential to apply thin coats of the
Hi-Temp 600 ZN HA Primer 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 600 ZN HA Primer 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 600 ZN HA Primer. 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 600 ZN HA Primer 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 AV115-FX (.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 at 30:1.
Adjust pressure as needed. Hold guns 10"-12" from the
surface at right angles. Lap each pass 50%. When brushing
and rolling, use only quality brushes and rollers.
Mixing
Hi-Temp 600 ZN HA Primer is a two package coating system.
The liquid base component and zinc dust must be
mixed together prior to use. Sift zinc dust into base using
mechanical agitation for mixing. Mix material 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.
