What it is and why choose it
Intergard 7600 Part A (Indivisible Kit) is a light-coloured, pure epoxy universal primer designed for marine environments. It provides good abrasion resistance and anticorrosive protection and is suitable for application at low substrate temperatures down to -5°C. When mixed with its dedicated curing agent (Part B KUA764) it forms a two-component coating for interior and exterior use on vessels in newbuilding, maintenance and repair, or on-board maintenance.
This primer can be applied directly over mechanically prepared, approved shop primers and is compatible with controlled cathodic protection systems. It holds multiple marine certifications for fire performance and food-contact grain carriage, making it suitable for a broad range of professional marine specifications.

Surface preparation (summary)
- General: All surfaces must be clean, dry and free from contamination. High-pressure fresh water wash to remove salts, oil, grease and soluble contaminants (SSPC-SP1 solvent cleaning as reference).
- Newbuilding:
- Remove weld spatter, smooth weld seams and sharp edges.
- Damaged shop primer and weld areas: blast clean to Sa2½ (ISO 8501-1:2007) or power tool to Pt3 (JSRA SPSS:1984).
- Approved intact shop primers: clean, dry and free from soluble salts.
- Unapproved shop primers: remove by blast cleaning to Sa2½; in some cases sweep blasting to an International Paint standard (e.g. AS2 or AS3) may be acceptable.
- Major refurbishment:
- Abrasive blast to Sa2 (ISO 8501-1:2007). If oxidation occurs prior to coating, reblast to the specified standard.
- Alternatively, hydroblasting to International Paint HB2 or slurry blasting to SB2, where flash rust is no worse than HB2M or SB2M.
- North America (marine): SSPC-SP10 may be used in place of Sa2½; SSPC-SP6 in place of Sa2; SSPC-SP11 in place of Pt3.

FAQ
-
Is Intergard 7600 Part A suitable for low-temperature application?
Yes. When mixed with Part B, Intergard 7600 can be applied to substrates down to -5°C. However, overcoating at low temperatures may require higher temperatures for subsequent coats to fully cure.
-
Can I apply this primer directly over existing shop primer?
Yes, provided the shop primer is approved, intact, clean, dry and free from soluble salts and contaminants. Damaged or unapproved shop primer must be blast cleaned or treated to the specified standards before application.
-
What mixing ratio should I use?
The required mix ratio is 3 volumes of Part A to 1 volume of Part B (KUA764). Always mix complete units supplied by the manufacturer.
-
Which application method is recommended for large areas?
Airless spray is recommended for large areas. Brush and roller application are suitable for small areas and may require multiple coats to reach the specified film thickness.
-
Does Intergard 7600 have any fire or food-contact approvals?
When used as part of an approved scheme, the product has certifications for fire resistance (Marine Equipment Directive compliant, surface spread of flame, smoke and toxicity) and food contact for carriage of grain.
-
What is the theoretical coverage?
The theoretical coverage is 5.44 m²/litre at 125 microns dry film thickness, without allowance for loss factors.
-
How should the surface be prepared before application?
Surfaces must be clean, dry and free from contamination, with salts, oil and grease removed by high-pressure fresh water wash and solvent cleaning. Blast or hydroblast to the specified standard (e.g. Sa2½, Sa2, HB2, SB2) depending on the situation.
-
Can I weld through or on top of the coated steel?
Welding or flame cutting on metal coated with this product will generate dust and fumes. Appropriate personal protective equipment and local exhaust ventilation are required.
-
What is the shelf life of the kit?
When stored correctly at 25°C in unopened containers, the shelf life is 15 months, subject to re-inspection thereafter.
-
Is thinning required?
Thinning with GTA220 is not normally required. If thinning is considered under extreme conditions, do not exceed limits set by local environmental legislation.

Section 8 – Individual protection measures
Intergard 7600 Part A is classified as a flammable liquid that causes skin irritation, can cause serious eye damage and may cause an allergic skin reaction. Appropriate personal protective equipment (PPE) and engineering controls are essential during handling and application.
Engineering controls and hygiene
- Use only with adequate ventilation; apply local exhaust or process enclosure where necessary.
- Ventilation and engineering controls must keep airborne contaminants below recommended limits and prevent flammable atmospheres.
- Use explosion-proof ventilation and electrical equipment in hazardous areas.
- Wash hands, forearms and face thoroughly after handling and before eating, drinking or smoking.
- Contaminated work clothing should not leave the workplace and must be washed before reuse.
- Ensure eyewash stations and safety showers are close to the work area.
Eye and face protection
- Wear chemical splash goggles and/or a face shield that meet an approved standard whenever there is a risk of splashes, mists or vapors.
- If inhalation hazards exist, a full-face respirator may be required instead of goggles.
Hand protection
- Wear chemical-resistant, impervious gloves complying with an approved standard.
- For prolonged or frequently repeated contact: use gloves with protection class 6 (breakthrough time > 480 minutes according to EN374). Recommended materials: Viton or nitrile, thickness ≥ 0.38 mm.
- For brief contact: use gloves with protection class 2 or higher (breakthrough time > 30 minutes according to EN374). Recommended material: nitrile, thickness ≥ 0.12 mm.
- Inspect and replace gloves regularly, especially if damaged. Performance can be reduced by physical/chemical damage or poor maintenance.
Body and other skin protection
- Select protective clothing based on the task and associated risks; approval by a specialist is recommended.
- When there is a risk of ignition from static electricity, wear anti-static protective clothing (overalls, boots and gloves) compliant with EN 1149.
- Use suitable protective footwear and any additional skin protection required by the risk assessment.
Respiratory protection
- Where ventilation is inadequate or exposure limits may be exceeded, wear a respirator conforming to EN140 with type A/P2 filter or better, selected as part of a formal respiratory protection program.
- Dry sanding, flame cutting and welding of dry paint films will generate hazardous dust and fumes. Wet methods are preferred; if not possible, appropriate respiratory protection and local exhaust ventilation are required.
Environmental exposure controls
- Emissions from ventilation and process equipment must comply with local environmental protection legislation.
- Where necessary, use fume scrubbers, filters or engineering modifications to reduce emissions.
