Applications and use cases

Intended uses

• Newbuilding: Primary or universal primer over mechanically prepared shop primers or blasted steel in shipyards and industrial fabrication.
• Maintenance and repair: For refurbishment of existing structures following appropriate surface preparation by abrasive blasting, hydroblasting or mechanical methods.
• On-board maintenance: Suitable for on-board touch-up and maintenance in marine environments, including internal areas where compatible overcoats are specified.

Typical substrates and preparation

• Steel at newbuild:
  • Remove weld spatter; smooth weld seams and sharp edges.
  • Repair areas of shop primer damage by blast cleaning to Sa2½ (ISO 8501-1:2007) or power tooling to Pt3 (JSRA SPSS:1984).
  • Intact, approved shop primers must be clean, dry and free from soluble salts and contamination.
  • Unapproved shop primers: fully remove by blast cleaning to Sa2½.
• Major refurbishment:
  • Fresh-water wash to remove dirt and contamination.
  • Remove oil and grease to SSPC-SP1 (solvent cleaning).
  • Abrasive blast to Sa2 (ISO 8501-1:2007) or hydroblast to International Paint standard HB2M/H.
• Repair / On Board Maintenance (OBM):
  • Mechanically clean corrosion to St3 (ISO 8501-1:2007) or hydroblast to HB2M/H.
  • Abrade surrounding intact coatings and feather edges.
• North American marine standards (alternative): SSPC-SP10 instead of Sa2½; SSPC-SP11 instead of Pt3 or St3; SSPC-SP6 instead of Sa2.

Application conditions

• Mixing: Material is supplied as two containers forming a complete unit. Always mix a full unit in the supplied proportions.
  1. Agitate Part A (base) with a power agitator.
  2. Add the entire contents of Part B (curing agent) to Part A and mix thoroughly with a power agitator.
• Recommended temperature of material for application: 25–30°C before mixing and application.
• Substrate temperature limits:
  • Do not apply or cure below 5°C.
  • Substrate temperature should not exceed 40°C.
• Damp-surface tolerance: Can be applied to damp, drying surfaces but not to wet surfaces, standing water or droplets. If water collects at the bottom of a finger-marked “V” on the surface, it is too wet and must be dried before coating.
• Flooding/immersion: The coating can continue curing once immersed in water, but early immersion may slow cure and produce soft films. Observe the “Before Flooding” times.
• Two-coat schemes: When Intergard 5000 is used as a two-coat system, Intergard 5000 Aluminium must always be applied as the first coat.
• Compatibility: Do not use Intergard 5000 to maintain or overcoat one-component coatings.

Cleaning and work stoppages

• Do not allow mixed paint to remain in hoses, guns or spray equipment.
• Flush all equipment thoroughly with International GTA220 after use and during prolonged stoppages.
• Once a unit is mixed it should not be resealed; for long interruptions, start again with freshly mixed units.
• Dispose of surplus material and empty containers in accordance with applicable regulations.

• Use explosion-proof ventilation and equipment where there is a risk of flammable vapours.
• Wash hands, forearms and face thoroughly after handling, before eating, drinking, smoking and at the end of the work period.
• Contaminated work clothing should not leave the workplace and should be washed before reuse.
• Ensure eyewash stations and safety showers are close to the workstation.

Eye and face protection

• Wear chemical splash goggles or equivalent eye protection complying with approved standards whenever there is a risk of exposure to splashes, mists, gases or dusts.

Hand protection

• Wear chemical-resistant, impervious gloves complying with an approved standard whenever handling the product.
• For prolonged or frequently repeated contact, gloves with protection class 6 (breakthrough time > 480 minutes according to EN374) are recommended. Suggested materials: Viton or nitrile, thickness ≥ 0.38 mm.
• For brief contact, gloves with protection class ≥ 2 (breakthrough time > 30 minutes according to EN374) are recommended. Suggested material: nitrile, thickness ≥ 0.12 mm.
• Replace gloves regularly and immediately if damaged. The effective protection time can be reduced by physical or chemical damage or poor maintenance.

Body and other skin protection

• Select protective clothing based on the tasks and risks involved, and have it approved by a specialist before use.
• Where there is risk of ignition from static electricity, wear anti-static protective clothing (overalls, boots and gloves) conforming to EN 1149.
• Use appropriate protective footwear and any additional skin protection measures as indicated by the workplace risk assessment.

Respiratory protection

• Select a respirator that meets an appropriate standard or certification, based on the hazard and potential exposure, and use it within a formal respiratory protection program.
• Where local exhaust ventilation does not adequately control airborne contaminants, wear a respirator conforming to EN140 fitted with an A/P2 filter or better.
• Dry sanding, flame cutting and welding of the dry paint film can generate hazardous dust and fumes; wet sanding/flatting should be used where possible, and respiratory protection must be provided if exposure cannot be otherwise controlled.

Environmental exposure controls

• Check emissions from ventilation and process equipment to ensure compliance with environmental protection legislation.
• Where necessary, fit fume scrubbers, filters or modify process equipment to reduce emissions to acceptable levels.
