SURFACE All surfaces to be coated should be clean, dry and free from contamination. Prior to application, all
PREPARATION surfaces should be assessed and treated in accordance with ISO 8504:2000.
Where necessary, remove weld spatter and where required smooth weld seams and sharp edges.
Oil or grease should be removed in accordance with SSPC-SP1 solvent cleaning.
Abrasive Blast Cleaning
Best performance will always be achieved when Enviroline 222 is applied to surfaces prepared by
abrasive blast cleaning to Sa3 (ISO 8501-1:2007) or SSPC-SP5. Where Enviroline 222 is not to be
used in high heat and/or aggressive service, preparation to Sa2½ (ISO 8501-1:2007) or SSPC-SP10
may be acceptable. A sharp, angular surface profile of 3-5 mils (75-125 microns) is recommended.
Contact International Protective Coatings for further information.
Enviroline 222 must be applied before oxidation of the steel occurs. If oxidation does occur the entire
oxidized area should be reblasted to the standard specified above. Surface defects revealed by the
blast cleaning process should be ground, filled or treated in the appropriate manner.
The preferred method of holding the blast standard is by dehumidification. Alternatively, an approved
holding primer may be used.
Concrete Surfaces
Refer to International Protective Coatings for specific recommendations.
APPLICATION Mixing Material is supplied in two containers as a unit. Complete units should be
stored, mixed and applied in accordance with the Enviroline Application
Guidelines.
Mix Ratio 2 part(s) : 1 part(s) by volume
Working Pot Life 77°F (25°C)
15 minutes
Plural component Recommended Refer to Enviroline Application Guidelines for more
airless spray details.
Airless Spray Suitable Refer to Enviroline Application Guidelines for more
details.
Air Spray Not suitable
(Pressure Pot)
Brush Suitable Can be used for the touch-up of small areas or for
stripe coating of welds and edges.
Thinner Not normally required Refer to Enviroline Application Guidelines for specific
advice.
Cleaner Enviroline 71C
Work Stoppages Do not allow material to remain in hoses, gun or spray equipment. Thoroughly
flush all equipment with Enviroline 71C. Once units of paint have been mixed,
they should not be resealed and it is advised that after prolonged stoppages,
work recommences with freshly mixed units.
Clean Up Clean all equipment immediately after use with Enviroline 71C. It is good
working practice to periodically flush out spray equipment during the course of
the working day. Frequency should depend upon amount sprayed,
temperature and elapsed time, including any delays.
All surplus material and empty containers should be disposed of in accordance
with appropriate regional regulations/legislation.

PRODUCT The detailed Enviroline Application Guidelines should be consulted prior to use.
CHARACTERISTICS
This datasheet provides general guidance on the use of Enviroline 222. Specific project
requirements will be dependent upon the service end use and operating conditions of the tank
or vessel. Always consult International Protective Coatings to confirm that Enviroline 222 is
suitable for contact with the product to be stored.
The detailed project coating specification provided by International Protective Coatings must be
followed at all times.
Stripe coating is an essential part of good working practice and as such should form part of any lining
specification.
For heavily pitted or porous steel, spray apply approximately 50% of the required film thickness and
follow immediately with a short nap roller or squeegee to work material into the bottom of pitted areas.
For plural component airless spray application, best results will be achieved when the product is heated
prior to application; Part A (Resin) to a maximum of 140°F (60°C) and Part B (Hardener) to a maximum
of 105°F (40°C). For airless spray application, best results will be achieved when each component of
the product is heated prior to application to 95-100°F (35-37°C).
Surface temperature must always be a minimum of 5°F (3°C) above dew point.
Use the following chart for preferred temperature conditions. These conditions plus adequate
ventilation must be maintained throughout the curing cycle.
Substrate Temperature Air Temperature
Preferred 70-120°F (21-49°C) 70-100°F (21-38°C)
Minimum 55°F (13°C) 55°F (13°C)
After the coating system has cured hard, the dry film thickness should be measured using a suitable
non-destructive magnetic gauge to verify the minimum applied system thickness. The coating system
should be free of all pinholes or other holidays. The cured film should be essentially free of runs, sags,
drips, inclusions or other defects. All deficiencies and defects should be corrected. The repaired areas
shall be retested and allowed to cure as specified before placing the finished lining into service.
Post-curing is not necessary for most applications, but Enviroline 222 may be post-cured to expedite
curing or increase chemical resistance for extremely aggressive environments. Post-cure for a minimum
of 2 hours at 250°F (121°C) or 6-8 hours at 150°F (66°C) for maximum resistance.
Maximum continuous dry temperature resistance for Enviroline 222 is 300ºF (149ºC).
Note: VOC values are typical and are provided for guidance purpose only. These may be subject to
variation depending on factors such as differences in color and normal manufacturing tolerances.
Low molecular weight reactive additives, which will form part of the film during normal ambient cure
conditions, will also effect VOC values determined using EPA Method 24.
SYSTEMS Enviroline 222 should always be applied to correctly prepared substrates. When a primer is required as
COMPATIBILITY part of the coating specification, consult International Protective Coatings for specific advice.
Enviroline 222 is designed as a single coat system. It must only be overcoated with itself should re-
coats or touch-up be required.

SAFETY This product is intended for use only by professional applicators in industrial situations.
PRECAUTIONS All work involving the application and use of this product should be performed in compliance with all relevant national
Health, Safety and Environmental standards, regulations and legislation.
Proper ventilation must be provided during application and afterwards during curing (refer to product datasheets for
typical curing times) to ensure safe limits and prevent fires and explosions. Forced extraction will be required in
confined spaces. Ventilation and/or respiratory personal protective equipment (airfed hoods or appropriate cartridge
masks) must be provided during application and curing. Take precautions to avoid skin and eye contact (overalls,
gloves, goggles, masks, barrier cream, etc).
Before use, obtain, read and then follow the advice given on the Material Safety Data Sheets (Base and Curing
Agent if two-pack) and the Health and Safety section of the Coatings Applications Procedures for this product.
In the event that welding or flame cutting is performed on metal coated with this product, dust and fumes will be
emitted which will require the use of appropriate personal protective equipment and adequate local exhaust
ventilation.
The detailed safety measures are dependent on application methods and the work environment. If you do not fully
understand these warnings and instructions or if you cannot strictly comply with them, do not use the product and
