Thin-Film Vinyl Ester Coating


This coating coating is a thin film flake filled
catalyzed vinyl ester system that exhibits excellent resistance
to acids, salts, oils, grease and aliphatic organics. It is
recommended for dilute alkaline environments.
Typical Uses
• Structural steel
• Chemical process equipment
• Rail Tanker Cars, Over the Road Tankers
• Immersion services for many dilute acids
• Can be applied over concrete or steel
• Excellent resistance to acids
• Low permeability
• Reinforced with laminar flake particles
Chemical Resistance
Information on the chemical resistance properties will be
furnished on request.

Surface Preparation
Metal - For immersion or intermittent splash and spillage
conditions, abrasive blast to “White Metal” in accordance with
Specifications SP-5 or
NACE Specification #1. For fumes and dry environments,
abrasive blast to “Near White” in accordance with SP-10 or
NACE #2. A minimum surface profile of 3.0 mils is required.
Concrete – Abrasive blasting or scarification to remove
laitance and surface contaminants is recommended. Concrete
must be thoroughly cured, free of oils, curing solutions and
mold release agents, dust and must be dry at time of
application. Use ASTM D 4263 (plastic sheet test method) to
ensure concrete is moisture free. If moisture is detected, retest
until dry.

Mixing Ratio

By Volume

HJ-A142 Primer


HJ-A005 Resin

1 gal

#2 Hardener

2.5 oz



322 Resin

1 gal

#3 Hardener

2 oz

The coating system consists of a primer, spray applied base
coat and topcoat, with a nominal dry film thickness of 16 to
mils. It can be applied on concrete and metal surfaces with
proper surface preparation.
Prime surfaces with 2.0 to 5.0 wet mils of HJ-A005 .
Use HJ-A142 Primer with the addition of HJ-powder (5.2 lbs per 5 gal unit) when spark testing (high
voltage holiday testing) will be conducted on concrete.
Mechanically premix 322 resin for 2 minutes prior
to adding hardener. After initial mixing, add 2 oz of #3C
Hardener per gallon of 322 resin and mix three
additional minutes.
Apply 322 resin and hardener at 11 to 13 mils
WFT to yield 8 to 10 DFT, target of 9 mils DFT. Allow to
harden. Repeat for second coat application.
Application Equipment
May be applied by spray, brush or roller
Airless Spray

Conventional Spray

Brush or Roll
Application may require an additional coat to obtain
recommended film thickness.
None required. DO NOT THIN.

Store in a cool, dry and covered location away from fire
hazards and direct sunlight. Minimum shelf life* at 70°F (21°C)
for products indicated below:
HJ-A142 Primer 6 months
322 6 months
Higher temperatures will shorten the shelf life of these
products. The packing drums are to be kept tightly sealed and
are to be resealed each time materials have been removed.
All liquid products are to be stored in a frost-free place.
Store in cool, dry area [50°- 90° F (10° - 32° C)] away from
direct sunlight, flame or other hazards.
322 contains vinyl ester resins and
cumene peroxide catalyst. The product’s components have
been formulated to optimize physical characteristics such as
filling capacity, abrasion, moisture and chemical resistance
while minimizing hazardous physical and health factors
encountered during application. A concerted effort is made to
be aware of the latest chemical toxicological information and
to apply this knowledge in a responsible manner to insure
product safety.
During application of 322 materials,
always wear gloves and appropriate work clothing to minimize
contact. Ventilation is required with special consideration for
enclosed or confined areas. Air movement must be designed
to insure turnover at all locations in work area and adjacent
areas to avoid buildup of heavy vapors. Use caution when
handling flammable liquids, eliminate sources of ignition from
work area and containers with residues.
Observe safe storage practices by separating resins from
hardeners, by keeping solvents in a cool area, free of sources
of ignitions.
Product Material Safety Data Sheets are available and should
be consulted when handling products. These products are for
industrial and professional use only; application directions
must be followed.
