Polyurethanes are widely used in coatings, adhesives, and sealants across various industries, including construction, transportation, and electrical applications. However, traditional polyester- and polyether-based polyurethanes often face limitations in hydrolysis resistance, chemical stability, oxidation resistance and other durability features under extreme conditions. In many of these applications, fire resistance is also a crucial requirement, especially for passive fire protection materials used in walls, floors, ceilings, railway components, cables, and gaskets.
ETERNACOLL® polycarbonate diols offer a superior solution by enhancing durability in polyurethane formulations. These advanced diols improve long-term performance, ensuring coatings, adhesives, and sealants retain their original properties even under extreme conditions. Tests confirm that polyurethanes based on ETERNACOLL® outperform polyester- and polyether-based materials in resistance to heat (120°C for 50 days), water exposure (80°C for 40 days), and chemical immersion (100°C for 30 days).
Additionally, ETERNACOLL® polycarbonate diols enhance fire resistance without the need for halogen-based systems, achieving UL 94 V-2 classification, with some formulations reaching V-0 and V-1 levels. This means self-extinguishing properties, preventing the spread of flames while maintaining structural integrity.
By integrating ETERNACOLL® polycarbonate diols, manufacturers can develop fire-resistant, long-lasting polyurethane coatings, adhesives, and sealants that exceed industry standards.
