Etalon 5400EH Epoxy Hardener Grey, 250ml

Dedicated Hardener for Etalon 5400EP Epoxy Primer

The Etalon 5400EH-B025 Epoxy Hardener is not a universal hardener. It is specifically formulated as Component B of the Etalon 5400EP 2K Epoxy Primer 3:1 system.

Combined with the corresponding Etalon 5400EP-A075 Grey Epoxy Primer, it initiates the chemical curing process required to create a strong and durable epoxy coating.

The 250ml package is designed to pair with:

750ml Etalon 5400EP Epoxy Primer

providing the correct:

3:1 mixing ratio by volume.

Together, the two components form a professional 1-litre epoxy primer system.

Designed for Marine & Yacht Applications

The Etalon 5400EP epoxy system is particularly suitable for demanding marine refinishing and maintenance applications.

Once correctly mixed, the system provides an anti-corrosive epoxy primer suitable for yacht and boat surfaces including:

• Steel
• Ferrous metals
• Aluminium
• Fiberglass / GRP
• Existing compatible coatings
• Body fillers
• Properly prepared repair areas

Its versatility makes it useful for yacht refits, hull and superstructure repairs, metal component refinishing and professional marine maintenance.

Excellent Anti-Corrosion Foundation

Metal surfaces onboard yachts are constantly exposed to moisture, humidity and challenging environmental conditions.

A properly applied epoxy primer creates an important protective layer between the substrate and subsequent coating system.

When used with Etalon 5400EP Primer, the 5400EH Hardener contributes to the formation of a coating designed to provide:

• Anti-corrosive protection
• Strong adhesion
• Surface sealing
• Resistance in demanding environments
• A durable base for subsequent coatings

This makes the system particularly useful when preparing aluminium and steel components before painting.

Suitable for Aluminium, Steel & Fiberglass

One of the major advantages of the Etalon 5400EP epoxy system is its broad substrate compatibility.

The complete mixed system can be applied to correctly prepared:

Steel & Ferrous Metal

Suitable for steel surfaces after rust, contamination and loose material have been removed and the substrate has been correctly degreased.

Aluminium

Suitable for properly cleaned, abraded and degreased aluminium surfaces.

This makes it particularly useful for yacht structures, aluminium components, brackets and other marine hardware.

Fiberglass / GRP

The epoxy primer can also be used on correctly prepared fiberglass surfaces, making it valuable for yacht and boat refinishing.

Existing Coatings & Fillers

It may also be applied over compatible existing coatings and properly prepared body fillers as part of a professional refinishing system.

Suitable for Surfaces Exposed to Water

The Etalon 5400EP epoxy primer system is specified for marine use and can be applied to surfaces intended to be submerged in water, provided correct surface preparation and the complete coating system requirements are followed.

This makes the Etalon epoxy system especially relevant for professional yacht and boat repairs where reliable substrate protection is required.

Correct Mixing Ratio Is Essential

For proper curing and performance, the hardener must be mixed with the corresponding Etalon 5400EP primer in the correct ratio.

Mixing Ratio by Volume

3 parts 5400EP Primer : 1 part 5400EH Hardener

For the standard small pack:

750ml Primer + 250ml Hardener

Mixing Ratio by Weight

5 parts Primer : 1 part Hardener

Accurate mixing is essential. Too much or too little hardener can negatively affect curing, adhesion and final coating performance.

Long Working Time

Once the primer and hardener are correctly mixed, the system offers a useful working time for professional applications.

Pot Life: approximately 7–9 hours

This provides enough time for larger yacht repair or refinishing jobs without requiring the material to be applied immediately after mixing.

Only mix the quantity required for the planned work.

Multiple Application Methods

The complete Etalon 5400EP epoxy system can be applied with several professional methods, including:

• HVLP spray gun
• Conventional spray equipment
• Airless spray equipment
• Roller
• Electrostatic spray equipment

This versatility allows the same epoxy system to be used for anything from smaller component repairs to larger marine surfaces.

Why Choose Etalon 5400EH Epoxy Hardener?

A 2K epoxy primer can only achieve its intended properties when used with the correct hardener and mixing ratio.

The Etalon 5400EH is specifically formulated for the Etalon 5400EP 3:1 epoxy primer system, ensuring the correct curing reaction and helping the coating achieve its intended adhesion, durability and anti-corrosion characteristics.

For yacht owners, professional painters, refit yards and crew carrying out technical maintenance, using the correct matched hardener removes uncertainty and helps produce consistent professional results.
