Understanding FFAST™ Technology: The Science Behind AquaPy®'s Superior Droplet Performance 

How Film Forming Aqueous Spray Technology Transforms Airborne Insect Control

In professional pest management, the effectiveness of a space spray depends largely on one critical factor: how long spray droplets remain suspended in the air. The longer droplets stay airborne, the greater the likelihood they will collide with flying insects, resulting in faster knockdown and improved control. This is where FFAST™ (Film Forming Aqueous Spray Technology) provides a measurable advantage and why it is central to the performance of products such as AquaPy®.  

What Is FFAST™ Technology?

FFAST™ is a patented formulation technology designed to enhance the behaviour of water-based spray droplets. In conventional aqueous sprays, water evaporates rapidly. As droplets lose moisture, they shrink, lose mass, and fall from the air before reaching their intended targets. FFAST™ addresses this challenge by forming a protective polymer-based film around each droplet. This film significantly reduces evaporation, allowing droplets to maintain their effective size for longer periods and remain suspended in the air.

At the heart of FFAST™ is an innovative film-forming technology that protects each spray droplet from rapid evaporation. The result is longer airborne suspension, improved coverage, and greater insect contact - delivering the performance professionals expect from a premium space-spray solution.

How the Droplet Coating Forms: The Three-Stage Mechanism

Stage 1 – Atomisation and Initial Water Loss

As droplets are released into the air, water begins to evaporate rapidly due to the surrounding temperature and airflow.

Stage 2 – Migration of Long-Chain Alcohols

The formulation contains specialised long-chain alcohol molecules. As water evaporates, these molecules migrate toward the droplet surface.

Stage 3 – Surface Film Formation

The molecules pack tightly together, creating a stable, continuous membrane around the droplet. This protective film restricts water diffusion and slows further evaporation.

Why Droplet Size Matters in Space Spraying

For ULV and fogging applications, AquaPy® performs optimally when droplets remain within the 15–30 μm range.

Without protection, water-based droplets in this size range can:

FFAST™ significantly reduces this effect.

Technical comparisons indicate that:

The result is oil-like airborne performance without the operational disadvantages associated with oil-based products.

Performance Benefits for Pest Control Operators

1. Longer Airborne Suspension = Higher Hit Rate

Extended droplet hang time increases the probability of contact with flying insects such as:

This contributes to AquaPy®'s reputation for delivering superior airborne performance.

  

2. Cleaner Water-Based Application

FFAST™ enables a water-based EW (Emulsion in Water) formulation to behave similarly to an oil-based spray while avoiding many associated drawbacks, including:

3. Consistent Performance Across Application Methods

FFAST™ has demonstrated performance across multiple application technologies, including:

This versatility allows AquaPy® to support space-spray and surface-spray applications from a single formulation.

 

4. Suitable for Sensitive Environments

Because AquaPy® is water-based, low odour, and non-flammable, it is particularly well suited to:

5. Stable Performance at Elevated Temperatures

Thermal fogging can accelerate droplet evaporation. The FFAST™ protective film helps stabilise droplet size under these conditions, supporting consistent airborne performance even when exposed to heat.

 

How FFAST™ Compares with Traditional Oil-Based Formulations

Conventional oil-based aerosols are valued for their low evaporation rates and prolonged airborne suspension.

FFAST™ formulations offer comparable or improved benefits, including:

This enables pest control operators to achieve high-performance space treatments while moving toward cleaner and safer chemistry.

 

Summary

FFAST™ Technology provides AquaPy® with a significant formulation advantage:

✅ A protective droplet coating forms in less than one second

✅ Evaporation is dramatically reduced

✅ Droplets remain airborne longer

✅ Airborne contact with insects increases

✅ Knockdown and control performance are enhanced

By combining the airborne performance traditionally associated with oil-based space sprays and the safety and cleanliness of a water-based EW formulation, AquaPy® represents an advanced solution for professional pest control operations, high-compliance environments, and demanding space-spray applications.
