What it is and why choose it
INTERLINE 994 PARTE A INDIVISIBLE KIT is the base component (Part A) of Interline 994, a two-pack novolac phenolic epoxy cargo tank coating from International Marine Coatings. Designed for newbuilding and maintenance and repair, it provides chemical-resistant protection for cargo and grey water tanks.
When correctly mixed with its dedicated curing agent TCA995 (Part B), Interline 994 is suitable for the carriage of an extensive range of aggressive cargoes, including solvents and chemicals, clean and dirty petroleum products, as well as vegetable and animal oils. The system has a semi-gloss finish and is approved for food contact in accordance with FDA and EU regulations when used as part of an approved scheme.

FAQ
1. What is INTERLINE 994 PARTE A INDIVISIBLE KIT exactly?
It is the base component (Part A) of Interline 994, a two-pack novolac phenolic epoxy cargo tank coating. It must be mixed with curing agent TCA995 (Part B) before use.
2. Which cargoes can the Interline 994 system carry once fully cured?
When used in an approved scheme, it is suitable for an extensive range of aggressive cargoes including solvents and chemicals, clean and dirty petroleum products, and vegetable and animal oils. International Paint should be consulted to confirm suitability for specific cargoes and any required post-cure.
3. Is the system approved for food contact?
Yes. When used as part of an approved scheme, Interline 994 is compliant with FDA section 175.300 and with EU Framework Directive 1935/2004 for food contact.
4. How should the surface be prepared before application?
Steel surfaces should be abrasive blast cleaned to Sa2½ (ISO 8501-1:2007), with weld spatter removed and sharp edges smoothed. Any oxidation occurring after blasting must be removed by reblasting to the specified standard.
5. What application methods are recommended?
Airless spray is recommended for large areas, using a 0.38–0.58 mm (15–23 thou) tip and at least 176 kg/cm² (2500 psi) fluid pressure. Brush and roller may be used for small areas, often requiring multiple coats to reach the specified film thickness. Conventional spray is not recommended.
6. At what temperatures can I apply the coating?
The steel temperature must be at least 10°C and at least 3°C above the dew point. The minimum of 10°C must be maintained during application (including between coats) and for a minimum of 48 hours after the final coat.
7. What are the key environmental limits during curing?
Relative humidity must not exceed 50% at 10–15°C and must not exceed 80% at temperatures above 20°C. For 15–20°C, specific guidance is given in the Interline 994 Application Guidelines.
8. How long is the pot life after mixing Part A and Part B?
Pot life ranges from 6 hours at 10°C to 1.5 hours at 35°C. Always respect the specified pot life limits and do not reseal mixed units.
9. How should equipment be cleaned?
All spray and mixing equipment should be thoroughly cleaned with International GTA415 or GTA822 immediately after use and periodically during the working day.
10. What should I do if welding or flame cutting is required on coated steel?
Welding or flame cutting on steel coated with this product will generate dust and fumes. Appropriate personal protective equipment and adequate local exhaust ventilation are required. In North America, work should follow ANSI/ASC Z49.1 “Safety in Welding and Cutting”.

Section 8 – Individual protection measures
The following information is based on the Interline 994 Grey Part A Safety Data Sheet and applies to handling and application of the product. Selection of PPE must be based on a site-specific risk assessment.
- General hygiene measures:
- Wash hands, forearms and face thoroughly after handling and before eating, drinking or smoking.
- Contaminated work clothing should not be taken out of the workplace and must be washed before reuse.
- Ensure eyewash stations and safety showers are located close to work areas.
- Eye and face protection:
- Wear chemical splash goggles and/or face shield complying with an approved standard when there is risk of splashes, spray or mist.
- If inhalation hazards require a full-face respirator, this may also provide eye protection.
- Hand protection:
- Wear chemical-resistant, impervious gloves complying with EN374 or equivalent.
- For prolonged or frequently repeated contact: use gloves with protection class 6 (breakthrough time >480 minutes); recommended materials: Viton or nitrile, thickness ≥ 0.38 mm.
- For brief contact: protection class 2 or higher (breakthrough time >30 minutes); recommended material: nitrile, thickness ≥ 0.12 mm.
- Replace gloves regularly and immediately if damaged; effectiveness can be reduced by physical or chemical damage or poor maintenance.
- Body protection:
- Select protective clothing based on the task and associated risks.
- Where there is a risk of ignition from static electricity, wear anti-static protective clothing including coveralls, boots and gloves, in line with EN 1149.
- Other skin protection:
- Use appropriate chemical-resistant footwear and any additional skin protection required by the task, approved by a specialist.
- Respiratory protection:
- When ventilation is inadequate, wear a respirator conforming to EN140 with type A/P2 filter or better.
- Respirators must be used under a respiratory protection program that ensures proper selection, fit and training.
- Dry sanding, flame cutting and welding of the dry coating generate hazardous dust and fumes; use wet methods where possible or provide effective local exhaust ventilation and appropriate respiratory protection.
- Environmental exposure controls:
- Emissions from ventilation or process equipment must comply with environmental regulations; scrubbers, filters or engineering changes may be required to reduce emissions.
