HUG CHEM, a China-based manufacturer, presents FH-101102, a bio-based polyol engineered for polyurethane (PU) coatings. This high-performance material is classified as a slightly branched polyether/polyester polyol, designed to function as a reactive component in 2-part polyurethane coating systems when combined with isocyanates. As a universal co-polyol, it plays a key role in modifying coating properties, particularly in extending gel time while contributing to the formation of elastic, UV-stable coatings.
FH-101102 aligns with the growing demand for sustainable materials, as it is derived from plant-based raw materials—a focus area where HUG CHEM has made notable advancements. This bio-based formulation supports efforts to reduce reliance on fossil resources and improve the carbon footprint of polyurethane products, making it a suitable choice for industries prioritizing environmental responsibility.
Universal Co-polyol: Its versatile nature allows it to integrate seamlessly into various 2-part PU coating formulations, adapting to different performance requirements.
Hydrophobic Properties: The polyol exhibits strong water repellency, which reduces the coating’s sensitivity to moisture during the curing process—a critical factor in maintaining coating integrity in humid environments.
Reactive Diluent: It acts as a reactive diluent, aiding in adjusting the viscosity of coating systems without compromising the final product’s mechanical properties.
Elastic Performance: Coatings formulated with FH-101102 demonstrate soft, elastic characteristics, enhancing their ability to withstand minor substrate movements or impacts.
Gel Time Prolongation: By extending gel time, it provides a longer working window for application, improving ease of use in industrial coating processes.
Solvent-Free and 100% System Compatibility: The formulation contains no solvents, reducing volatile organic compound (VOC) emissions, and is compatible with full-system polyurethane setups.
UV Stability: The resulting coatings maintain their properties under UV exposure, contributing to long-term durability in outdoor or light-exposed applications.

Protective coatings for substrates requiring flexibility, such as certain plastics, metals, or composites.
Casting compounds where elasticity and moisture resistance are essential, such as gaskets or flexible seals.
Outdoor coatings exposed to UV radiation, where its UV-stable properties help maintain appearance and performance over time.
The hydrophobic nature of FH-101102 is particularly beneficial in regions with high humidity or frequent exposure to water, as it minimizes issues like blistering or adhesion loss during and after curing.
