VOC 326 g/lt as supplied (EPA Method 24)


VOC values are typical and are provided for guidance purposes only. These may be subject to variation
depending on factors such as differences in colour and normal manufacturing tolerances.



When used as part of an approved scheme, this product has the following certification:
• Food Contact - Carriage of Grain (NOHA)
• Tank Coatings - B1 Classification of Ballast Tank Coatings (DNV/Marintek tested)
• Fire Resistance - Marine Equipment Directive compliant
• Potable Water - Certification for tanks greater than 5,000 gallons (ANSI Standard 61)
Potable Water Certification issued by external bodies is dependent upon formulation and/or manufacturing site.
Based on this, products supplied in different territories may not be approved to all of the standards listed above.
Consult your International Paint representative for details.


Consult your International Paint representative for the system best suited for the surfaces to be protected. If overcoating Intershield 300V with antifoulings or single pack finishes, the first coat of material must be applied while the Intershield 300V is soft to thumbprint or slightly tacky. When using in cargo holds, consult the Intershield 300V Cargo Hold Application Guidelines. For tank coating, consult International Paint for the detailed coating procedures that should be followed.


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.


Where necessary, remove weld spatter and smooth weld seams and sharp edges. Weld seams and areas of shop primer damage or breakdown should be blast cleaned to Sa2½ (ISO 8501-1:2007) or power tooled to Pt3 (JSRA SPSS:1984).
Intact, approved, shop primers must be clean, dry and free from soluble salts and any other surface contaminants. Unapproved shop primers will require complete removal by blast cleaning to Sa2½ (ISO 8501-1:2007). In some cases sweep blasting to a defined International Paint standard (eg AS2 or AS3) may be acceptable. Consult your International Paint representative for specific recommendations.


Abrasive blast clean to minimum Sa2 (ISO 8501-1:2007) or International Paint Hydroblasting Standard HB2M. If oxidation has occurred between blasting and application of Intershield 300V, 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.


Consult International Paint.

Consult your International Paint representative for specific recommendations.
When full abrasive blasting is carried out, a sharp angular surface profile of 50-100 microns is recommended.



Material is supplied in 2 containers as a unit. Always mix a complete unit in the proportions supplied. Once the
unit has been mixed it must be used within the working pot life specified.
(1) Agitate Base (Part A) with a power agitator.

International GTA822/GTA415


Work Stoppages and Cleanup

Do not allow material to remain in hoses, gun or spray equipment. Thoroughly flush all equipment with International GTA822/GTA415. 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 GTA822/GTA415. 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.


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."


All work involving the application and use of this product should be performed in compliance with all relevant national Health, Safety & Environmental standards and regulations.

Prior to use, obtain, consult and follow the Material Safety Data Sheet for this product concerning health and safety information. Read and follow all precautionary notices on the Material Safety Data Sheet and container labels. If you do not fully understand these warnings and instructions or if you can not strictly comply with them, do not use this product. Proper ventilation and protective measures must be provided during application and drying to keep solvent vapour concentrations within safe limits and to protect against toxic or oxygen deficient hazards. Take precautions to avoid skin and eye contact (ie. gloves, goggles, face masks, barrier creams etc.) Actual safety measures are dependant on application methods and work environment.



Intershield 300V should be high pressure fresh water washed and/or solvent washed prior to overcoating, where necessary, to ensure removal of any surface contamination that has accumulated. Suitable for use on tanker decks subject to Classification Society Regulations. Intershield 300V may be applied at substrate temperatures down to -5°C, however consideration should be given when overcoating at low temperatures as the remainder of the system may require higher temperatures to achieve full cure.

For North America: if overcoating Intershield 300V direct with antifoulings, the first coat of antifouling must be applied while the Intershield 300V is still tacky. For use in potable water tank linings, as a two coat system with a 10 mils dft, nominal and cure of 30 days minimum at 25°C (77°F) and 50% relative humidity.

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 above the dew point. For optimum application properties bring the material to 21-27°C, 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.
