Polyurethane-urea hybrids are widely used in coatings, adhesives and sealants for applications requiring high durability and resistance, such as industrial flooring, parking lots, and high-traffic areas. However, traditional polyester and polyether-based polyurethane formulations often struggle with hydrolysis resistance, chemical stability, and abrasion resistance, leading to degradation over time and increased maintenance costs.
ETERNACOLL® polycarbonate diols provide a high-performance alternative, significantly improving the durability and mechanical properties of polyurethane-urea hybrids. These diols enhance hydrolytic and chemical stability, allowing coatings, adhesives, and sealants to withstand exposure to organic solvents, gasoline, break fluids and automotive oils without compromising their integrity. This resistance ensures long-lasting performance, even in the most demanding environments.
Another key benefit of ETERNACOLL®-based formulations is their superior abrasion resistance, improved hardness, and enhanced adhesion to substrates such as concrete and binders. Compared to conventional polyester-based coatings, formulations with ETERNACOLL® exhibit a 90% increase in surface hardness, 60% better abrasion resistance, and greater flexibility under stress. Their high scratch resistance and elongation at break contribute to enhanced durability, reducing the risk of cracking or failure under extreme mechanical loads.
These properties make ETERNACOLL®-based polyurethane-urea coatings, adhesives, and sealants the ideal solution for industries requiring long-lasting and resilient materials. By incorporating these advanced diols into their formulations, manufacturers can extend the lifespan of treated surfaces, reduce downtime, and optimize operational efficiency.
