INTERGARD 821 PART A INDIVISIBLE KIT

What is INTERGARD 821 PART A INDIVISIBLE KIT and why choose it

INTERGARD 821 PART A INDIVISIBLE KIT from International Marine (AkzoNobel) is the base component of Intergard 821, a two-pack epoxy filler designed for marine and industrial steel protection. When combined in a 1:1 mix ratio with Part B curing agent, it forms a high-build, 100% solids epoxy system used as an anode shield and as a structural filler for pitted or damaged steel surfaces in aggressive environments such as ship hulls and offshore structures. The information below is based on publicly available product data and may not be exhaustive; some values may vary by region or revision and should be verified against the latest official technical data sheet.

Main features

• Two-pack epoxy filler system: Part A (base) used with Part B (curing agent EAA821) to create a solvent-free epoxy filler.
• High-build, 100% volume solids: Designed to be applied in very thick layers to rebuild and protect heavily pitted steel while minimising shrinkage.
• Anode shield application: Commonly used as a dielectric shield around ICCP (impressed current cathodic protection) anodes and other critical areas of the hull.
• Filler for pitted steel: Formulated to level deep corrosion pits and fabrication defects, restoring a smooth and protective profile before overcoating.
• Suitable for newbuilding, maintenance and repair: Can be used in shipyards, dry docks or on-board maintenance jobs.
• Trowel or knife application: Applied by trowel/knife only, allowing precise placement and high film thickness in a single operation.
• High film thickness capability: Typical thickness for anode shielding is around 240 mils (approximately 6000 microns) dry, with higher builds possible when used as a filler. Exact maximums can vary and should be confirmed in the latest data sheet.
• Low VOC content: Published data indicates a VOC content around 74 g/L (EPA method), but this value should be verified for the specific region and kit supplied.

• Flash point (typical, approximate, unverified for all markets): Part A around 149°F (about 65°C); Part B around 144°F (about 62°C); mixed product around 144°F (about 62°C). Check the latest safety documentation for precise values.

Applications and use cases

• Anode shielding around ICCP systems: Used as a dielectric shield around impressed current cathodic protection anodes to help control current distribution and protect the surrounding hull structure.
• Filling pitted or corroded steel: Ideal for rebuilding surfaces that have suffered pitting corrosion on ship hulls, ballast tanks, and other immersed or splash-zone steel areas, prior to overcoating with suitable protective systems.
• Newbuilding: Applied during construction of new vessels or marine structures as part of a comprehensive corrosion protection system specified by International Marine or project engineers.
• Maintenance and repair: Used in dockyard and on-board maintenance to repair damaged coatings, restore protection around anodes and rebuild corroded areas.
• On-board maintenance: With the correct preparation and safety measures, it can be used by crews for targeted repairs during service intervals, following shipyard or manufacturer instructions.

Performance and suitability for a specific project will depend on surface preparation, environmental conditions, overcoating system and application quality. For critical applications, always confirm compatibility and specification with the latest official technical data sheet and, where necessary, with a qualified coating advisor.

FAQ – INTERGARD 821 PART A INDIVISIBLE KIT

1. What exactly is included in the INTERGARD 821 PART A INDIVISIBLE KIT?

This designation usually refers to the base component (Part A) of the Intergard 821 epoxy filler supplied in a fixed, non-splittable package size. It is intended to be mixed 1:1 by volume with the corresponding curing agent (Part B, EAA821). Packaging options and whether Part B is included in the commercial offer may vary by distributor; always check your specific product listing or consult your supplier.

2. Do I need a separate curing agent with this product?

Yes. Intergard 821 is a two-pack epoxy system that requires mixing Part A with Part B (curing agent EAA821) before use. Part A alone will not cure or provide the intended protective properties.

3. On what surfaces can Intergard 821 be used?

According to available product information, Intergard 821 is formulated for steel, particularly pitted or corroded steel, and for creating an anode shield around ICCP systems on ship hulls and similar structures. It is not typically specified for non-ferrous substrates unless clearly allowed in the project specification.
