FH-10100 is a branched polyether polyol specifically engineered for use in polyurethane coatings. As a reactive component in 2-part polyurethane systems, it functions by forming chemical bonds with isocyanates, resulting in coatings characterized by high cross-link density. This structural attribute contributes to the material’s overall performance in various coating applications, making it a suitable choice for formulations requiring enhanced mechanical and chemical properties.
Developed by HUG CHEM, this bio-based polyol aligns with the growing industry focus on sustainable raw materials, offering a viable alternative to petroleum-derived counterparts without compromising functional performance.
When used in combination with FH-10750 (another polyol in the FH series), FH-10100 facilitates an increase in the glass transition temperature (Tg) of the final coating. This improvement is significant for applications where thermal stability and resistance to temperature fluctuations are required, as higher Tg values often correlate with better dimensional stability at elevated temperatures.
The branched molecular structure of FH-10100 promotes the formation of a dense cross-linked network when reacted with isocyanates. This network structure enhances the coating’s overall integrity, contributing to improved hardness and resistance to physical wear.
The polyol exhibits inherent hydrophilic characteristics, which can be advantageous in formulations where controlled water interaction is desired. This property allows for better compatibility with water-based additives and can aid in the dispersion of components during coating preparation.
Coatings formulated with FH-10100 demonstrate enhanced resistance to a range of chemicals, including solvents, acids, and alkalis. This makes the polyol suitable for applications where the coated surface may be exposed to harsh chemical environments.
Bio-based composition: Derived from plant-based raw materials, reducing reliance on fossil resources and supporting lower carbon footprint initiatives.
100% system compatibility: Designed to integrate seamlessly into complete polyurethane coating formulations without the need for additional modifiers.
Solvent-free: Eliminates the presence of volatile organic compounds (VOCs) associated with solvents, aligning with environmental regulations and safety standards.
High cross-link density: Ensures robust coating performance under demanding conditions.
Strong chemical resistance: Provides long-term protection against chemical degradation.

For optimal results, FH-10100 is typically used in combination with other polyols from the FH series. When employed as the sole polyol component, it is essential to homogenize the mixture for at least 10 minutes to ensure proper compatibility with isocyanates, which helps maintain viscosity stability and coating performance.
