Coating hazards GB 30981.2-S-Pb≤1000-NC; complies with GB 30981.2-2025
When used as part of an approved scheme, the product holds the following certificates: • Food contact — complies with US FDA regulations for dry foodstuffs • Food contact — grain cargoes (NOHH) • Potable water — potable water cargoes (NSF-WRc) (BS6920). Certificates for potable water tanks issued by external bodies depend on the formulation and/or place of manufacture. As such, products supplied in different countries may not be approved to all the standards listed above.
Intershield One-2-One has also been tested according to the following standards, depending on the formulation and/or place of manufacture: - Ballast water tanks — IMO PSPC WBT (LR). Confirm the certificate status with the local representative.
For ballast water tanks, a multi-coat Intershield One-2-One Aluminium coating system is recommended.
For the paint system best suited to the surface to be protected, consult your local representative.
Applied in accordance with the standard Worldwide Marine Specifications.
All surfaces to be coated must be clean, dry and free of contaminants.
Wash with high-pressure or ordinary fresh water as appropriate, and remove all oil, grease, soluble contaminants and other foreign matter in accordance with the SSPC-SP1 solvent cleaning standard.
In-service maintenance — bare steel and corroded areas: clean by hand or power tool at least to St2 (ISO 8501-1:2007). Note: all mill scale shall be removed; areas not suitably treated by chipping or needle gun shall be spot-blasted at least to Sa2 (ISO 8501-1:2007). Generally, this method is suitable for grade C or D steel.
Intershield One-2-One is suitable for application over aged existing coating systems. When recoating over aged coatings or exposed topcoats with chalking, light sanding of the surface is recommended before application of Interstores primer. Loose or flaking coatings shall be removed down to firmly adhering coating, and the areas to be coated shall be sanded. When Intershield One-2-One is applied, ensure that the overlap between the new coating and the existing coating is 2–3 cm (1 inch) wide.
Before applying a full coat over a certain general type of coating, a small trial is recommended.
For specific advice, consult your local representative.
Note: for marine environments in North America, the following surface preparation standards may be used: SSPC-SP6 in place of Sa2 (ISO 8501-1:2007), SSPC-SP2 in place of St2 (ISO 8501-1:2007).
The paint is supplied as a unit in two separate containers. Once a unit is mixed, it shall be used within the specified pot life.
| (1) | Prepare a separate container. |
|---|---|
| (2) | Stir the base (Component A) with a power stirrer and pour it all into a separate container. |
| (3) | Stir the curing agent (Component B) with a power stirrer, mix all of the curing agent (Component B) with the base (Component A), and stir thoroughly with a power stirrer. |
| (4) | If a small quantity is required, mix equal quantities of Component A and Component B in a second container. |
Normally no thinning is required. Under extreme conditions, consult your local representative for application advice. Do not thin beyond the limits of local environmental regulations.
Recommended nozzle tip size 0.48–0.64 mm (19–25 thou); total fluid pressure at the nozzle not less than 211 kg/cm² (3000 psi)
Conventional spray application is not recommended.
Recommended
Do not leave paint in hoses, spray guns or spray equipment. Flush all equipment thoroughly with International thinner. Once mixed, paint should not be resealed; if work is interrupted for too long, mix a fresh batch before resuming application.
All equipment shall be cleaned with International GTA220/GTA822 immediately after use. Spray equipment shall be flushed with this solvent. Periodically flushing spray equipment during the working day is good practice. The frequency of cleaning depends on factors such as the quantity sprayed, temperature and elapsed time (including interruptions). Pay close attention to the condition of the paint. Do not exceed the pot life after mixing.
All surplus paint and empty containers must be disposed of in accordance with appropriate local regulations/laws.
If welding or flame cutting is performed on metal coated with this product, dust and fumes will be released; use suitable personal protective equipment and local exhaust ventilation. In North America, follow the instructions in ANSI/ASC Z49.1 “Safety in Welding and Cutting”.
All work related to the application and use of this product must comply with national health, safety and environmental protection standards and regulations.
Before using this product, obtain, read and follow the health and safety information in the Material Safety Data Sheet for the product. Read and observe all precautions in the Material Safety Data Sheet and on the container label. If these warnings and requirements are not fully understood, or cannot be strictly observed, do not use the product. During application and drying of the product, provide adequate ventilation and protective measures to keep solvent vapour concentrations within safe limits, so as to prevent poisoning or oxygen deficiency. Take protective measures to avoid skin and eye contact with the product (e.g. gloves, goggles, face shield, barrier cream). Specific safety measures depend on the application method and working environment.

Optimum performance is obtained when this coating is applied to steel prepared to St2 (ISO 8501-1:2007).
As with all epoxy-based coatings, Intershield One-2-One will chalk when exposed to ultraviolet light.
Recoat data are for guidance only and depend on local climatic and environmental conditions. For specific advice, consult your local International Paint representative.
Apply in good weather. The temperature of the surface to be coated shall be at least 3 °C above the dew point, and the relative humidity shall not exceed 85%. Unless otherwise instructed, for optimum application performance, bring the paint temperature to 21–27 °C before mixing and application. Unmixed paint (in tightly closed containers) shall be stored as specified in the 'Storage' section of this data sheet. The technical and application data herein are intended as general guidance for establishing a coating procedure.
Test performance results are obtained under controlled laboratory conditions; International Paint does not claim that the published test results, or any other tests, accurately represent the results obtained in all site environments. Because application, environmental and design factors vary greatly, care shall be taken in coating selection, performance verification and use.
