Decoding AE Sealcoat: What's Inside That Black Protective Layer?

When it comes to protecting your asphalt investment, sealcoating plays a vital role. And if you've done some research, you've likely encountered the term "AE sealcoat." But what exactly is it, and what's it made of? Let's break down the composition of asphalt emulsion (AE) sealcoat and understand its key ingredients.

Understanding Asphalt Emulsion (AE):

AE sealcoat, as the name suggests, is based on asphalt emulsion. This means it's a mixture where asphalt, a semi-solid form of petroleum, is suspended in water. This process makes the asphalt more fluid and easier to apply at lower temperatures than traditional coal tar sealers.

Key Ingredients in AE Sealcoat:

1. Asphalt:

   • The primary ingredient is asphalt, which provides the binding and protective properties. It creates a flexible, durable layer that shields the asphalt pavement from the elements.

   • The type and grade of asphalt used can vary, impacting the final product's performance.

2. Water:

   • Water acts as the dispersing agent, allowing the asphalt to be in a liquid state. This makes it easier to apply the sealcoat evenly.

   • The water eventually evaporates as the sealcoat cures, leaving behind the solid asphalt layer.

3. Emulsifying Agents:

   • These are crucial ingredients that keep the asphalt suspended in the water. They prevent the asphalt from separating and settling.

   • Different types of emulsifiers are used, and they influence the sealcoat's stability and curing time.

4. Mineral Fillers (Aggregate):

   • Sand, crushed stone, or other mineral aggregates are often added to AE sealcoat.

   • These fillers provide several benefits:

     • Improved traction and skid resistance.

     • Increased durability and wear resistance.

     • Enhanced aesthetic appeal.

     • They also help to thicken the sealcoat.

5. Additives:

   • Various additives can be included to enhance specific properties of the sealcoat.

   • These may include:

     • Latex or polymers for increased flexibility and durability.

     • Accelerators to speed up the curing process.

     • Pigments to enhance the color.

Why AE Sealcoat is Popular:

• Environmental Friendliness: Compared to coal tar sealers, AE sealcoats are generally considered more environmentally friendly, as they contain fewer volatile organic compounds (VOCs).

• Ease of Application: AE sealcoats are easier to apply, especially at lower temperatures.

• Flexibility: The emulsion formula allows for greater flexibility, reducing the risk of cracking in colder climates.

Important Considerations:

• The quality of AE sealcoat can vary depending on the manufacturer and the specific formulation.

• Proper application is crucial for optimal performance.

• Understanding the ingredients and their roles can help you make informed decisions about your asphalt maintenance.

By understanding what AE sealcoat is made of, you can better appreciate its protective qualities and ensure you're making the right choice for your asphalt surfaces.
