Why Bio-Dur E560?

Tab

What is the Bio-Dur E560 used for?

Bio-Dur E560 is 100% solids, solvent-free epoxy coatings designed for above or below water applications, including:

• Pools, fountains, and water features
• Marine structures and splash zones
• Wastewater tanks and clarifiers
• Steel, concrete, and masonry repair
• Leak sealing and structural reinforcement

The Bio-Dur E561 is used as a barrier coat in heavy duty service applications.

Can these coatings really be applied underwater?

Yes this product is specifically formulated to:

• Bond to wet or submerged surfaces
• Cure underwater without washing off

They can even be submerged immediately after application, though they should not be exposed to heavy wave action until cured.

Are these coatings VOC-free and safe for enclosed areas?

Yes. All three are:

• 100% solids
• VOC-free (or essentially zero VOC)
• Solvent-free formulations

This makes them safer for confined spaces and environmentally sensitive areas.

How thick should these coatings be applied?

Typical application thickness:

• 30–40 mils DFT (dry film thickness)
• High-build, often one-coat systems

The E561 can be applied up to 40-60 mils DFT (dry film thickness). For help with product selection for YOUR project reach out to us at 630-675-4509 or [email protected]

Key Differences: E560 vs E561 vs E563

What is the difference between E560, E561, and E563?

The main differences come down to viscosity and cure speed:

• E560 → Standard viscosity, versatile, general-purpose
• E561 → Thicker “paste-like” consistency for higher build applications
• E563 → Fast-curing version for rapid return-to-service

When should I use E560?

Use E560 when you need:

• A balanced, brushable/rollable coating
• Standard working time (~40 min pot life)
• General underwater or above-water protection

It’s the most versatile, all-purpose option.

When should I use E561?

Use E561 when:

• You need a thicker, non-sag material
• Working on vertical or overhead surfaces
• Performing patching, filling, or fairing

It has a higher viscosity (“light paste”) consistency, making it ideal for build-up repairs.

When should I use E563 (quick cure)?

Use E563 when:

• You need fast turnaround or emergency repairs
• Downtime must be minimized
• Cold temperatures are slowing cure times

It has:

• Shorter pot life (~20 minutes)
• Much faster service times (as fast as ~3 hours light service)

Which product cures the fastest?

E563 cures the fastest, followed by E560/E561.

• E563 → Rapid cure (hours)
• E560/E561 → Standard cure (14–72 hours depending on service level)

Which product is best for large coating projects?

E560 is typically preferred for:

• Large surface areas
• Roller or spray applications
• Standard cure timelines

It offers the best balance of workability and performance.

Performance & Application Questions

How long do these coatings last underwater?

When properly applied, these coatings provide:

• Long-term corrosion protection
• High abrasion resistance
• Chemical resistance in harsh environments

They are designed for permanent protection in aggressive conditions, including wastewater and marine exposure.

What is the pot life and working time?

• E560 / E561 → ~40 minutes at 77°F
• E563 → ~20 minutes at 77°F

Higher temperatures will reduce working time significantly.

How soon can the surface be put back into service?

• E563 → As little as a few hours (light service)
• E560 / E561 → ~14 hours light service, ~72 hours heavy service

Can these coatings handle chemical exposure?

Yes. They are commonly used in:

• Wastewater environments
• Industrial tanks
• Chemical exposure areas

They provide strong resistance to corrosion, abrasion, and chemicals.

Do I need a primer?

In most cases, no primer is required because:

• These epoxies are designed to bond directly to properly prepared substrates
• They can adhere to wet surfaces

However, surface prep is critical for performance.

Can I apply these coatings in cold or hot temperatures?

Yes, typical application range:

• 45°F to 110°F

For cold environments, E563 is often preferred due to faster curing.

Buying & Selection Questions (SEO Gold)

Which Bio-Dur product should I choose?

• Choose E560 → for general-purpose coating projects
• Choose E561 → for thick repairs, vertical surfaces, or filling voids
• Choose E563 → for fast-track jobs and quick return-to-service

Are these coatings good for pools and fountains?

Yes—these are excellent for:

• Concrete pools
