VOC Compliant Air Drying Silicone Based Heat Resistant Coating
HJ-09D is a VOC compliant, air drying, silicone
based heat resistant coating that protects thermally
insulated austenitic stainless steel from chloride
induced stress corrosion cracking. HJ-09D
withstands temperatures to 1000°F (538°C). It is
formulated to contain the minimum amounts of
attainable chlorides, halides, sulfides, nitrates and
metals that induce external stress corrosion cracking.
Every batch of HJ-09D is tested by an
independent laboratory for leachable chloride content.
HJ-09D is formulated to meet the currently
accepted practice for selection of protective coatings
for stainless steel surfaces .
Carbon Steel and Austenitic Stainless Steel Surfaces
Under Thermal Insulation”.
Application to stainless steel surfaces where (1) the
benefits of HJ-09D 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.
• Insulated stainless steel piping, vessels and
• Nuclear power facilities where a high temperature
coating for stainless steel with minimum amounts of
chlorides, other halides, nitrates, sulfides and
metals is needed
• VOC compliant - 3.45 lb./ gal. (413 g./l.)
• Air Dries
• Withstands continuous temperature of 1000°F
• Free of heavy metal pigments.
• Does not contribute to weld embrittlement of
stainless steel welds.
• Prevents wet chlorides from the atmosphere or
process operations from coming into contact with
stainless steel surfaces.
• Easy to apply system
• Excellent bond to stainless steel without need to
abrasive blast (see Surface Preparation).
• Prevents insulation, which may contain chlorides,
from coming into contact with stainless steel
Not Recommended For
• Immersion service
• Interiors of stacks, breechings and scrubbers
• Uninsulated surfaces
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
dew point. Prior to application of HJ-09D, bring
material to 70°F (21°C) for optimal application
properties. For optimum protection apply two coats of
HJ-09D to a dry film thickness of 1.5-2.0 mils
(37-50 microns) per coat. Total recommended dry film
thickness is 3.0-4.0 mils (75-100 microns).
Conventional spray is the recommended method of
application. However, HJ-09D may also be
applied by airless spray, brush or roller. Do not apply
HJ-09D in heavier films than specified since
blistering may occur.
Provide material pot with agitator, regulators for fluid and air
pressure, and oil and moisture traps in supply line.
*Smaller hose diameter or length over 25 ft. may require
Air pressure to pump
Pump operating pressure
* 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.
Only thin HJ-09D with HJ-008 Thinner.
Do not thin with HJ-170 Thinner. Do not thin
beyond federal, state and/or local VOC (volatile organic
compound) emission regulations. Note: Use Honest joy
170 Thinner only in the surface preparation of small
stainless steel areas. Use of other thinners not
approved by Honest joy may hinder product
performance and void product warranty.
Dry Time 70°F (21°C) 50% RH
HJ-09D 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. Stainless steel
surfaces coated with HJ-09D in the air-dried
state can be handled and shipped prior to a heat cure
as long as shipping and handling procedures for thinfilmed
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 30
minutes. Equipment protected with the HJ-09D
in the air-dried state will heat cure when placed into
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.
