Environmentally friendly, high-performance formulation for impregnation
Our PFAS-free, silicone-free, water- and dirt-repellent, solvent-based alternative for modern textile and leather
applications is now available for your production.
The market for impregnating agents is under immense pressure to change. PFAS regulations are tightening whilst
the demand for the highest levels of water and dirt repellence remains high. Aerochemica presents a new, PFAS-
and silicone-free, solvent-based formulation for impregnation which proves in recognised tests that higher
environmental friendliness can be combined with high product performance.
Regulatory change meets performance requirements.
Fluorine-containing systems are coming under increasing regulatory pressure. For brands, retailers, and
distributors of impregnation products, this means existing technologies must be replaced without compromising
performance. Our new formulation has been developed to enable PFAS-free product strategies and avoid silicone-
based alternatives while maintaining existing performance standards.
Performance profile of the new formulation
The solution is a solvent-based system designed for even application and reliable wetting of fabrics. It has the
following technical properties:
• PFAS-free (fluorine-free)
• silicone-free
• solvent-based carrier system
• not water-soluble
• strong hydrophobic and dirt-repellent effect
• Preservation of breathability, feel and colour effect
Important for practical use: The material properties are generally retained, which is a decisive factor for high-
quality end products.
These fabrics are ideal for the following applications:
• Outdoor and functional clothing
• Footwear and leather goods
• Rucksacks, bags and luggage
• Tents and technical textiles
• Boat covers, parasols, garden textiles and lorry tarpaulin
A wide range of applications
This formulation is suitable for many types of fabric used in industrial and consumer applications.
• Polyester (PES)
• Cotton (CO)
• Polyamide/nylon (PA)
• Blended fabrics (PES/CO)
• High-tech technical textiles
• leather, suede, nubuck and smooth leather
Proven performance: A comparison was made with a fluorinated reference system.
The formulation’s performance was tested under standardised conditions using the AATCC 22:2021 spray
test/water repellence method and the EN 4920 method. Aerochemica’s PFAS-free impregnation and a fluorinated
reference product were applied to different fabric types and compared in the tests. Water repellence was
assessed according to the defined test conditions.
Key findings of the results:
The PFAS-free formulation demonstrates comparable water repellence to fluorinated systems across multiple
fabric types.
What this means in practical terms for companies offering impregnation products.
This offers brands, retailers, and distributors of impregnation products a clear strategic advantage.
• Early adaptation to PFAS regulations without any loss of performance
• Reduction of substitution and development risks
• Easy integration into existing solvent-based product range
• Consistent performance across different material classes
• Clear differentiation in the market from traditional fluorinated solutions
