Bio Based Polyol for PU Sealant

Overview of FH-40M400 Polyester Polyol

A notable feature of FH-40M400 is its 59% bio-based content, sourced from sustainable vegetable oils. This composition, verified through calculated data and mass balance principles, aligns with efforts to reduce reliance on fossil resources and improve the carbon footprint of end products—a core focus of HUG CHEM’s innovation in plant-based raw materials for polyurethane production.

Key Characteristics of FH-40M400

• Balanced Hardness and Flexibility: The unique combination of high-functionality polyol hardness and dimer-based flexibility ensures adaptability across diverse applications, from sealants to coatings.

• Durability: It demonstrates improved impact resistance at low temperatures, a critical trait for products exposed to varying environmental conditions. Additionally, it provides strong scrub resistance, enhancing long-term performance in high-wear scenarios.

• Chemical and Moisture Resistance: The polyol exhibits resistance to harsh substances, including aviation hydraulic fluids, and protects sealants from moisture-related damage—key for maintaining integrity in humid or chemically exposed environments.

• Production Efficiency: Formulations using FH-40M400 benefit from shorter drying times, contributing to faster production cycles and improved operational efficiency.

Applications

• Adhesives and Sealants: Its balanced properties make it ideal for formulating sealants requiring both flexibility and strength, ensuring reliable bonding and protection.

• Industrial and Protective Coatings: Enhances chemical resistance and drying performance in coatings designed to protect surfaces from corrosion, abrasion, or environmental stress.

• Automotive Coatings: Suitable for high-performance automotive finishes, where durability, resistance to fluids, and efficient curing are essential.
