Air Drying Self-Priming Heat And Corrosion Coating
HJ-1200Aseries coatings are VOC compliant,
air drying, self-priming, heat and corrosion resistant
coatings based on a silicone copolymer resin and a
highly effective corrosion inhibitive pigment system.
HJ-1200Aseries coatings are designed for
application to ambient temperature metal surfaces or
directly to hot metal surfaces up to 500°F (260°C) of
operating equipment*. They provide a tough,
chemically resistant, durable finish with excellent film
integrity and color stability. HJ-1200Aseries
coatings protect metal surfaces from corrosion and
weathering up to 500°F (260°C), with peaks to 600°F
(315°C). HJ-1200Aseries coatings are available
in a wide range of standard (see our Color Card)
and custom colors.
* HJ-1091 Aluminum is the only HJ-1200A series color which may not be applied to hot
surfaces above 0°F (93°C).
Application to surfaces where (1) the benefits of
HJ-1200Aseries coatings are needed, and
where (2) federal, state and/or local authorities require
high temperature coatings to be compliant with reduced
VOC (volatile organic compound) emission regulations.

Surface Preparation - Carbon Steel
1. To ensure optimum long-term coating system
performance, surfaces must be clean, dry and free
from dirt, oil, grease, salts, welding flux, mill scale,
rust, oxides, old paint, corrosion products or other
2. Remove all surface imperfections that will induce
premature coating system failure. Chip or scrape
off weld splatter. Grind down sharp and rough
edges, gouges, and pits.
3. Abrasive blast surface per specification SSPC-SP
10, “Near-White Blast Cleaning”. Abrasive used in blasting should be
selected carefully from materials of mesh size
required to produce the desired anchor pattern.
4. If abrasive blasting is not permitted, prepare
surface by power tool cleaning per SSPC-SP 11.
This method will provide a surface
equivalent to that provided by commercial blast
cleaning per SSPC-SP 6, including the desired
surface profile .
5. Feather out all edges of adjacent painted surfaces
after completion of surface preparation operations
and prior to application of the first coat of paint.
Surface Preparation - Stainless Steel
1. Surfaces must be clean and dry. Remove all oil,
grease, soil, drawing and cutting compounds, and
other foreign matter by methods outlined in Steel
Structures Painting Council Specification SSPC-SP
1, “Solvent Cleaning”.
2. DO NOT USE CHLORINATED SOLVENTS ON
STAINLESS STEEL SURFACES.
3. For large surface areas, steam clean with an
alkaline detergent, follow by a steam or fresh water
wash to remove detrimental residues.
4. For small surface areas, solvent wipe with
HJ-170 Thinner, a chloride free solvent,
using proper procedures and precautions to
Redisperse any settled-out pigments by stirring with a
paint paddle followed by thorough mixing to a uniform
consistency with an explosion-proof or air-driven power
mixer. Do not open containers until ready to use.
Keep lid on container when not in use.
Surface temperature must be at least 5°F (3°C) above

as a prime coat.
Uninsulated Stainless Steel*
For optimum protection apply two coats of Thurmalox
260C to a dry film thickness of 2.0-2.5 mils (50-62
microns) per coat. Total recommended dry film
thickness is 4.0-5.0 mils (100-125 microns).
*For application of other HJ-1200Aseries colors
to uninsulated stainless steel consult Honest joy
Conventional spray is the recommended method of
application, however HJ-1200Aseries coatings
may also be applied by airless spray, brush or roller.
Do not apply HJ-1200Aseries coatings in
heavier films than specified since blistering may occur.

Pump operating press.
* Use clean tips for fast, easy clean out.
Brush: Use only wooden-handled brush with short
China bristles. Do not use synthetic-bristled brushes.
Do not flood surface with coating. Brush out
thoroughly, maintaining a continuous wet edge and
uniform appearing paint film.
Roller: Use only wooden-handled roller with phenolic
shank and core, and 1/4-3/8” nap. Do not flood surface
with coating. Roll out excess coating on a suitable,
screened surface. Then roll out thoroughly,
maintaining a continuous wet edge and uniform
appearing paint film.
Procedures for Application to Hot
1. Flush spray equipment with HJ-008 Thinner
2. Thinning of HJ-1200Aseries coatings is not
normally required for spray application. For brush
or roller application, use up to 1/2 pint maximum of
HJ-162 Thinner per gallon of coating.
3. HJ-162 Thinner is a high flash point (102°F),
slow evaporating solvent formulated especially for
application to hot surfaces.
4. WARNING! DO NOT use any other solvents to thin
HJ-1200Aseries coatings. A fire hazard
may result from use of solvents with low auto
ignition temperatures when applying Thurmalox
260C series coatings to hot surfaces, and rapid
solvent evaporation can cause dry spray and poor
5. Use HJ-162 Thinner cautiously. Addition of
a small amount of thinner will cause a great
reduction in coating viscosity. Excessive thinning
will cause runs or sags.
6. For conventional spray use adequate air pressure
and volume to obtain proper atomization.
* Note: HJ-1091 Aluminum is the only
HJ-1200Aseries color which may not be applied
to hot surfaces above 0°F.
Be aware that procedures for applying coatings to hot
surfaces are somewhat different from those normally
used for application to ambient temperature surfaces.
The following factors should be taken into
a) Heat radiating from the surface and/or strong winds
will promote dry spray.
b) To avoid dry spray, always apply coatings
perpendicular to hot surfaces without stretching or
c) Perpendicular spraying will also minimize
overspray and lap marks due to dry spray and over
On each pass of the spray gun a thinner than normal
paint film must be applied to facilitate the heataccelerated
escape of solvents without leaving pinholes
Only thin HJ-1200Aseries coatings with
HJ-162 Thinner. Do not thin beyond federal,
state and/or local VOC (volatile organic compound)
emission regulations. Note: Use of other thinner not
approved by Honest joy may hinder product
performance and void product warranty. Also see
Procedures for Application to Hot Surfaces.
Dry Time at 70°F (21°C) 50% RH
HJ-1200Aseries coatings will air dry tack and
thumb print free within 6-8 hours. Allow 10-12 hours
dry time between coats. Allow 48 hours dry time prior
to shipping and handling if coating is not heat cured.
Surfaces coated with HJ-1200Aseries in the air
dried state can be handled and shipped prior to a heat
cure as long as shipping and handling procedures for
thin filmed systems are followed. Avoid mechanical
abrasion during shipping and handling. Higher
temperatures will reduce tack free, recoat and shipping
times. Allow one hour solvent flash off period before
heat curing or placing into service. Optimum film
properties require a heat cure of 350° F (177° C) for a
1/2 hour. Equipment protected with the Thurmalox
260C series coatings in the air dried state will heat cure
when placed into service.
Thoroughly flush spray equipment and hoses
immediately after use with HJ-008 Thinner.
Dismantle spray equipment and clean parts, brushes
and rollers with HJ-008 Thinner.
Store in cool, dry place with temperature between 50°F
and 100°F (10°C and 38°C). Keep container closed
when not in use.
WARNING: Flammable Liquid and Vapor
Keep away from heat, sparks and flame. Vapors may
cause flash fire. Do not breathe vapors or spray mist.
Avoid contact with eyes, skin and clothing. Use with
adequate ventilation during mixing and application.
Wear an appropriate, properly fitted organic vapor
cartridge-type respirator during and
after application unless air monitoring demonstrates
vapor/mist levels are below applicable limits. Follow
respirator manufacturer’s directions for respirator use.
Wash thoroughly after handling. Wear protective
gloves, chemical safety goggles and impervious
protective clothing. Use skin cream. In confined
spaces it is required to use a positive pressure
supplied-air respirator . Use
explosion-proof lights and electrical equipment. Use
only nonsparking tools and equipment. Wear
conductive and nonsparking footwear. Make certain all
electrical equipment is grounded. See Material Safety Data Sheet (MSDS)
for complete precautionary and disposal information.
If instructions and warnings cannot be strictly followed,
do not use this product.
