What is Intergard 410 Part A Indivisible Kit and why choose it
Intergard 410 Part A is the base component of a two-component, high build epoxy coating designed for use as an intermediate or finish coat on steel structures and other industrial and marine surfaces. When mixed with its dedicated curing agent (Part B EMA080) it produces a high performance coating with excellent chemical and abrasion resistance. It is suitable for newbuilding, maintenance and repair, and onboard maintenance, and can be used on structural steel, pipelines, dry cargo holds and underwater hull (boot topping) areas as part of an approved coating system.
This product is widely used in both industrial environments (offshore structures, chemical plants, power stations, pulp and paper plants) and marine applications where a durable anti-corrosive barrier and reliable film build are required.
Main features
- Two-component epoxy system: Part A (base) to be mixed with Part B (curing agent EMA080) in a 4:1 volume ratio.
- High build coating: Designed to achieve typical dry film thicknesses around 100–150 microns (marine sheet specifies 125 microns d.f.t.).
- High performance barrier protection: Provides an anti-corrosive barrier in aggressive corrosion conditions when used in a suitable coating system.
- Excellent chemical and abrasion resistance: Suitable for areas subject to mechanical wear and mild to medium chemical exposure.
- Versatile use: Can be used as a primer, coloured intermediate/undercoat for durable finishes or as a finish coat where a high decorative standard is not required.
- Application flexibility: Can be applied by airless spray, conventional air spray, brush or roller (brush/roller recommended for small areas only).
- Wide colour availability: Supplied in white (EMB000) and a wide range of colours via the Chromascan system.
- Semi gloss to gloss appearance: Industrial and marine epoxy finish with good film build and coverage.
- Certified performance (marine use): When used in approved systems it offers certification for food contact (grain carriage) and several fire performance standards.

Applications and use cases
Industrial protection
- Offshore structures exposed to aggressive marine atmospheres.
- Chemical plants and process areas with mild to medium chemical attack.
- Power stations and associated steelwork.
- Pulp and paper plants where mechanical and chemical resistance are important.
Marine environments
- Use on underwater hull and boot topping areas as part of an approved system.
- Dry cargo holds and other dry cargo spaces where grain and similar cargoes may be carried (when used in certified systems).
- Structural steel, piping and general onboard steelwork in new construction, maintenance and repair.
Concrete protection
- Protective system for concrete floors and walls subjected to light traffic and mild chemical attack.
- Concrete must be cured for at least 28 days, with moisture content below 6%, and properly prepared (clean, free from curing compounds, release agents and laitance; sweep blasted or acid etched before priming).
Role in coating systems
- As a primer or intermediate coat: Applied over a wide range of compatible primers including epoxy and zinc-rich systems (e.g. Intercure, Intergard and Interzinc primers as listed in the data sheet).
- As a finish coat: Can act as the final coat where high decorative appearance is not critical, acknowledging that epoxies will chalk and discolour on exterior exposure.
- Topcoat options: Can be overcoated with products such as Interfine 629HS, Intergard 740, Intergard 410 itself, or Interthane 990 for improved gloss and colour retention.
FAQ
-
Is Intergard 410 Part A a complete product?
No. Intergard 410 Part A is the base component of a two-component epoxy. It must be mixed with the dedicated curing agent Part B (EMA080) in a 4:1 volume ratio before application.
-
What application methods are recommended?
Airless spray is recommended for achieving maximum film build in a single coat. Conventional air spray, brush and roller can also be used, but brush and roller are recommended for small areas only and may require multiple coats.
-
On what surfaces can Intergard 410 be used?
It can be applied to properly prepared steel (including shop-primed steel and metallic zinc-primed steel) and to suitably prepared and primed concrete floors and walls. All surfaces must be clean, dry and free from contamination.
-
Does Intergard 410 provide UV-resistant colour and gloss?
No. Like all epoxies, Intergard 410 will chalk and discolour when exposed to sunlight. This does not normally affect anti-corrosive performance, but where long-term cosmetic appearance is required it should be overcoated with a recommended topcoat such as Interthane 990 or Interfine 629HS.
-
What are the minimum and maximum overcoating intervals?
At 25°C the typical minimum overcoating interval with Intergard 410 or Interthane 990 is 10 hours and the maximum is 7 days. At lower temperatures these intervals increase; at higher temperatures they decrease. Refer to the full temperature table for precise values.
-
Can it be applied in cold conditions?
Intergard 410 does not cure adequately below 5°C. For maximum performance ambient curing temperatures should be above 10°C, and the substrate temperature must be at least 3°C above the dew point.
-
Is thinning required?
Thinning is generally not required. Where necessary, only International GTA220 thinner should be used and not more than allowed by local environmental legislation.
-
How should equipment be cleaned?
All application equipment should be thoroughly cleaned with International GTA822. Do not allow mixed material to remain in hoses, guns or spray equipment.
-
What is the shelf life of Intergard 410 Part A?
The stated minimum shelf life is 12 months at 25°C, stored in dry, shaded conditions away from heat and ignition, subject to re-inspection thereafter.
-
Is Intergard 410 suitable for food-related cargo holds?
When used as part of an approved system, Intergard 410 carries certification for food contact in the transport of grain cargoes (NOHA). Consult International Paint for system details.
