Most industrial cleaning processes are running on chemicals that operators don’t fully understand—and can’t fully control.
You buy a solvent expecting consistency. It’s labelled, approved, and widely used.
But over time, performance drifts. Cleaning becomes inconsistent. Residues appear. Costs increase.
And no one can clearly explain why.
The Industry Problem
Chemical labels rarely tell the full story.
Many “standard” cleaning solvents are actually multi-component blends. While they may perform well initially, their composition can change during use.
In real operating conditions:
- Components evaporate at different rates
- The system begins to separate (“chemical drift”)
- The boil sump and rinse zone no longer match
- Recovered solvent is not the same as the original
The result is a process that gradually becomes unstable.
This leads to:
- Inconsistent cleaning performance
- Increased residue risk
- Higher solvent consumption
- Potential safety concerns, including flammability shift
You’re no longer running a controlled process—you’re managing a variable one.
The Solution: Stability by Design
Azeotropic solvents address this issue directly.
A true azeotrope behaves as a single, stable substance, even though it contains multiple components. It cannot be separated by distillation, meaning its composition remains constant.
That delivers:
- Stable boiling point
- No chemical drift
- Consistent cleaning performance
- Reliable recovery and reuse
What you start with is what you keep.
A Proven Alternative
True azeotropic products, such as Opteon™ SF80®, offer:
- Long-term stability in operation
- Non-flammability under normal operating conditions
- Consistent performance
- Effective recovery without composition change
In many cases, they can directly replace unstable blends—improving control, reducing waste, and lowering risk.
Fraser Tech Services – Your one stop-solution
The Fraser Technologies Approach
At Fraser Technologies, we see this problem regularly—customers trying to fix performance issues that are actually caused by unstable chemistry.
We don’t just supply solvents. We engineer stable, repeatable cleaning processes.
Our focus is to:
- Understand how your solvent behaves over time, not just at install
- Identify risks linked to blended or unstable systems
- Implement solutions that maintain process integrity and safety
- Support with ongoing optimisation and solvent management
Because a solvent that drifts is not a solution.
The Bottom Line
If you don’t understand how your solvent behaves over time, you don’t control your process.
Fraser Technologies exists to remove that uncertainty—delivering cleaning solutions that are stable, predictable, and built for real-world performance.
