What is Intergard 276 Part A Indivisible Kit and why choose it?
Intergard 276 is a two-pack epoxy primer, undercoat and tie-coat designed for marine environments. When mixed with its dedicated curing agent (Part B EGA089), it provides a matt epoxy coating for dry internal spaces such as accommodation areas and engine rooms, and for above-water steel surfaces. It is used both as a primer on prepared internal steelwork and as an intermediate undercoat/tie-coat between anticorrosive primers and a wide range of finishing topcoats.
This coating offers controlled film build, good coverage and compatibility with common marine epoxy and polyurethane systems. It is certified for fire resistance under the Marine Equipment Directive when part of an approved scheme, making it suitable for safety-critical shipboard areas.

Applications and use cases
As a primer for internal steelwork
- For dry internal spaces such as accommodation areas and engine rooms.
- All surfaces must be clean, dry and free from contamination.
- Remove weld spatter and smooth weld seams and sharp edges.
- Clean welds and damaged shop primer by:
- Grit blasting to Sa2 (ISO 8501-1:2007), or
- Power tooling to Pt3 (JSRA SPSS:1984) or St3 (ISO 8501-1:2007).
As an undercoat / tie-coat
- Applied over compatible anticorrosive primers in above-water areas.
- Acts as a tie-coat between epoxy anticorrosive systems and a wide range of topcoats such as Intergard 740 and Interthane 990.
- Primer surface must be clean, dry and free from contamination.
- Areas of breakdown or damage should be prepared to the specified standard, e.g. Sa2½ (ISO 8501-1:2007).
- Intergard 276 must be applied within the published overcoating intervals of the underlying primer.
- Over inorganic zinc silicate primers, thin Intergard 276 by 15–25% with International GTA220 to reduce pin-holing.

Section 8 – Individual protection measures
Intergard 276 contains flammable solvents and components classified for skin and eye irritation, skin sensitisation, respiratory irritation and specific target organ toxicity. When handling Part A, Part B and the mixed product, implement the following personal protective measures in conjunction with adequate engineering controls and ventilation.
Engineering and hygiene controls
- Use only with adequate ventilation; apply local exhaust or process enclosure to keep vapour concentrations below occupational exposure limits and lower explosion limits.
- Use explosion-proof ventilation and electrical equipment.
- 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 work areas.
Eye and face protection
- Wear chemical splash goggles and/or a face shield compliant with approved standards when there is a risk of liquid splashes, spray or mist.
- If significant inhalation hazard exists, use a full-face respirator in place of goggles.
Hand protection
- Wear chemical-resistant, impervious gloves compliant with EN374 or equivalent.
- For prolonged or frequently repeated contact, use gloves providing protection class 6 (breakthrough time > 480 minutes); recommended materials: Viton or nitrile, thickness ≥ 0.38 mm.
- For brief contact only, use nitrile gloves with protection class ≥ 2 (breakthrough time > 30 minutes), thickness ≥ 0.12 mm.
- Replace gloves regularly and immediately if damaged.
Skin and body protection
- Wear suitable protective clothing selected according to task and risk assessment.
- When there is a risk of ignition from static electricity, use antistatic protective garments (overalls, boots and gloves) compliant with EN 1149 or equivalent.
- Use appropriate protective footwear and additional skin protection as required.
Respiratory protection
- When ventilation is insufficient, wear a respirator conforming to EN140 fitted with an A/P2-type filter or better.
- Respirators must be used within a formal respiratory protection programme ensuring correct selection, fitting and training.
- Dry sanding, flame cutting or welding of the dry paint film can generate hazardous dust and fumes; use wet sanding where possible, and if exposure cannot be controlled by extraction, wear suitable respiratory protection.
