SiwoPUD®-FB-10

Advanced Waterborne Blocked Polyisocyanate Crosslinker for High-Temperature Curing

Characteristics:

Hydrophilic blocked aliphatic polyisocyanate

Supplied as:

85%

Storage:

The crosslinker should be stored in tightly sealed containers, protected against frost and away from direct sunlight.

Application:

FB-10 is a hydrophilic blocked aliphatic polyisocyanate designed for use in water-based coatings and adhesives that require curing under high-temperature baking conditions. Supplied at 85% solids, FB-10 offers excellent water solubility, superior adhesion, and durability, making it ideal for applications where heat resistance, high flexibility, and chemical resistance are required.

With an 11.0 ± 1% blocked NCO content and a viscosity range of 5000-15000 mPa·s, FB-10 provides the perfect balance of ease of application and high crosslink density. The crosslinker ensures efficient curing, even at high temperatures (up to 140°C), enabling the formulation of one-component polyurethane coatings that do not require additional hardeners.

The resulting paint films formulated with FB-10 deliver high flexibility, hardness, and resistance to water and solvents, achieving performance comparable to conventional two-component systems. The degree of crosslinking is highly adaptable, making FB-10 an ideal solution for manufacturers looking for high-performance coatings with minimal complexity.

This non-ionic crosslinker ensures compatibility with a wide range of polyurethane resins, offering enhanced dispersion and uniform crosslinking throughout formulations. Its application is particularly suitable for waterborne adhesives and coatings used in industries requiring tough, flexible, and durable finishes. Additionally, the water resistance and solvent resistance of the final films make them perfect for demanding applications in automotive, furniture, and industrial coatings.

For manufacturers seeking a high-performing polyurethane hardener for water-based systems, FB-10 is the solution to achieve exceptional performance under high-temperature baking conditions.
