The coatings industry is undergoing a profound transformation, driven by increasing regulatory pressure, sustainability targets, and the need to maintain high performance without relying on fluorinated chemistries. In this evolving scenario, Maflon has developed a fully integrated fluorine-free technology.
A New Approach to Water and Oil Repellency—Without Fluorine
Traditionally, fluorinated polymers have been the benchmark for water and oil repellency. Maflon’s R&D strategy has focused on overcoming this dependency by engineering fluorine-free polymer capable of delivering comparable.
The result is a new generation of fluorine-free solutions based on methacrylic polymers.
Fluorine-Free Penetrating Sealers for Stone, Tile and Concrete
At the core of Maflon’s surface protection portfolio is the HYDROSIN® ST line, a patented family of fluorine-free penetrating sealers developed for stone, tile, concrete and mineral substrates.
These systems are designed to:
-
deeply penetrate porous substrates
-
preserve the natural appearance of the surface
-
provide high oil repellency, stain resistance and easy-to-clean properties
HYDROSIN® ST sealers work within the substrate, ensuring long-lasting protection and UV resistance, even at low dosage levels. Both water-based and solvent-based versions are available, allowing formulators to optimize performance according to application requirements.
Crosslinking Technologies for Water-Based and Solvent-Based Systems
To further enhance durability, chemical resistance and long-term performance of fluorine-free formulations, Maflon has developed a new generation of crosslinking technologies specifically engineered for both water-based and solvent-based systems.
HYDROSIN® B Line – Blocked Isocyanates for Water-Based Systems
For aqueous formulations, Maflon introduces the HYDROSIN® B line, a patented family of blocked poly-isocyanates designed to meet modern safety, regulatory and processing requirements.
Key features of the HYDROSIN® B line include:
-
complete absence of MEKO, DMP, VOC and DIPA
-
low deblocking temperature, enabling energy-efficient curing
-
excellent compatibility, TDI & HDI.
-
improved durability of water and oil repellency, abrasion resistance and washing fastness.
HYDROSIN® BS Line – Advanced Blocked Isocyanates for Solvent-Based Systems
For solvent-based applications, Maflon offers the HYDROSIN® BS line, a new generation of high-performance blocked poly-isocyanates developed for demanding industrial coatings.
The HYDROSIN® BS line is characterized by:
-
MEKO, DMP & DIPA free formulations
-
low deblocking onset temperatures, among the lowest available on the market
-
BS-131 high efficiency in crosslinking hydroxyl-functional resins such as polyesters, acrylics and alkyds
These crosslinkers are ideal for coil coatings, automotive finishes, industrial protective coatings.
High-Performance Fluorine-Free Surfactants
The new HYDROSIN® line offers high-performance fluoro-free surfactants for both water-based and solvent-based systems. Designed to enhance wetting, leveling, and product stability, they effectively reduce surface tension even at low concentrations. Ideal for paints, adhesives, industrial cleaners, and polishes, HYDROSIN® ensures efficient and sustainable solutions for various industrial applications.
PROPERTIES:
-FLUORO-FREE – SUSTAINABLE SOLUTION
-EXCELLENT SURFACE TENSION REDUCTION
-ENHANCED WETTING AND LEVELING PROPERTIES
-HIGH COMPATIBILITY WITH WATER-BASED AND SOLVENT-BASED SYSTEMS
-EASILY SOLUBLE IN VARIOUS SOLVENTS
Fluorine-Free Solutions for Leather
Maflon has extended its fluorine-free technology to leather finishing, addressing the growing demand for sustainable alternatives.
Maflon’s fluorine-free leather treatments are designed to:
-
provide durable water repellency
-
maintain the natural look, softness and hand-feel of leather
-
offer partial oil repellency, sufficient for everyday protection against light oils and stains
Based on methacrylic polymers and advanced polymer dispersions, these products penetrate leather fibers effectively, ensuring long-lasting protection without altering surface aesthetics.
They can be applied in both pre-coat and top-coat systems and are suitable for full-grain, nubuck, suede and nappalan leathers.
