CERTIFICATION When used as part of an approved scheme, this material has the following certification:
􀁺 Food Contact - Carriage of Grain (NOHA)
Consult your International Paint representative for details.
SYSTEMS AND
COMPATIBILITY
Consult your International Paint representative for the system best suited for the surfaces to be protected.
SURFACE
PREPARATIONS
Use in accordance with the standard Worldwide Marine Specifications.
All surfaces to be coated should be clean, dry and free from contamination.
High pressure fresh water wash or fresh water wash, as appropriate, and remove all oil or grease, soluble
contaminants and other foreign matter in accordance with SSPC-SP1 solvent cleaning.
NEWBUILDING
Interzinc 22 may be applied over some fresh zinc silicate shop primers. International Paint should be consulted
regarding zinc silicate shop primers and the requisite surface preparation prior to their overcoating. Other types of
shop primer are not suitable for overcoating and will require complete removal by abrasive blast cleaning. Weld
seams and damaged areas should be blast cleaned to Sa2½ (ISO 8501-1:1988).
MAJOR REFURBISHMENT/REPAIR
Abrasive blast clean to Sa2½ (ISO 8501-1:1988). If oxidation has occurred between blasting and application of
Interzinc 22, the surface should be reblasted to the specified visual standard. Surface defects revealed by the blast
cleaning process, should be ground, filled, or treated in the appropriate manner.
A surface profile of 40-75 microns (1.6 - 3.0 mils) is recommended.
Consult your International Paint representative for specific recommendations.
NOTE:
For use in Marine situations in North America, the following surface preparation standards can be used:
SSPC-SP10 in place of Sa2½ (ISO 8501-1:1988)

APPLICATION
Mixing Interzinc 22 is supplied in 2 parts, a liquid Binder base component (Part A) and a Powder component (Part B).
The Powder (Part B) should be slowly added to the liquid Binder (Part A) whilst stirring with a mechanical agitator.
DO NOT ADD LIQUID TO POWDER. Material should be filtered prior to application and should be constantly
agitated in the pot during spraying. Once the unit has been mixed it should be used within the working pot life
specified.
Thinner Not recommended under normal conditions of use. Use International GTA803 or International GTA415 (USA) in
exceptional circumstances or to assist spray application at high termperatures (typically above 28°C (82°F)). Do
not thin more than allowed by local environmental legislation.
Airless Spray Recommended.
- Tip range 0.38 - 0.53mm (15-21 thou)
- Total output fluid pressure at spray tip not less than 112 kg/cm² (1600 p.s.i.)
Conventional Spray Gun DeVilbiss MCB or JGA Air Cap 704 or 765 Fluid Tip E
Brush Recommended for small areas only.
Roller Not recommended.
Cleaner International GTA803 or International GTA415 (USA)
Work Stoppages and
Cleanup
Do not allow material to remain in hoses, gun or spray equipment. Thoroughly flush all equipment with
International GTA803 or International GTA415 (USA). 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 all equipment immediately after use with International GTA803 or International GTA415 (USA). It is good
working practice to periodically flush out spray equipment during the course of the working day. Frequency of
cleaning will depend upon amount sprayed, temperature and elapsed time, including any delays. Do not exceed
pot life limitations. All surplus materials and empty containers should be disposed of in accordance with
appropriate regional regulations/legislation.
Welding In the event 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. In North America do so in accordance with instruction in ANSI/ASC Z49.1 "Safety in Welding and
Cutting."

LIMITATIONS The minimum overcoating interval is dependant on the relative humidity. At relative humidities less than 65% the
minimum recoat period may by extended. This should be confirmed by carrying out a solvent rub test. Consult
International Paint for details.
The maximum overcoating interval is normally indefinite but will be dependent on the weather and environmental
conditions. The Interzinc 22 surface must be clean, dry and free from soluble zinc salts and zinc corrosion product.
For overcoating procedures consult International Paint.
Overcoating information is given for guidance only and is subject to regional variation depending upon local climate
and environmental conditions. Consult your local International Paint representative for specific recommendations.
Apply in good weather. Temperature of the surface to be coated must be at least 3°C (5°F) above the dew point.
For optimum application properties bring the material to 21-27°C (70-80°F), unless specifically instructed
otherwise, prior to mixing and application. Unmixed material (in closed containers) should be maintained in
protected storage in accordance with information given in the STORAGE Section of this data sheet. Technical and
application data herein is for the purpose of establishing a general guideline of the coating application procedures.
Test performance results were obtained in a controlled laboratory environment and International Paint makes no
claim that the exhibited published test results, or any other tests, accurately represent results found in all field
environments. As application, environmental and design factors can vary significantly, due care should be
exercised in the selection, verification of performance and use of the coating.
