Low viscosity polycarbonate diols for high performing and durable polyurethanes coatings, adhesives & sealants and elastomers

With the aim of finding solutions that enhance the performance and durability of our products, one of the great innovations emerges: the use of polycarbonate diols. These diols are used to design long-lasting and high-performance polyurethane coatings, adhesives, and elastomers, especially in demanding industries such as oil and mining, construction, and industrial machinery.

What makes polycarbonate diol-based polyurethanes so exceptional is their ability to withstand harsh conditions and maintain their original properties over time. From resistance to hydrolysis, solvents, and chemicals, to thermal and oxidation stability, these materials offer outstanding performance even in extremely demanding environments.

However, a significant limitation has been the high viscosity of polycarbonate diols, making them difficult to handle in manufacturing processes. However, this is where an innovative solution comes into play: low viscosity polycarbonate diols, included in UBE’s ETERNACOLL® polycarbonate diols product line.

These low viscosity diols offer processability similar to standard polyether and polyester diols, making them easy to incorporate into various manufacturing processes. Additionally, their durability performance is comparable to that of traditional polycarbonate diols.

Key benefits of this innovation include viscosities closer to those of benchmark polyols, ease to formulate CASE polyurethanes,, and offering a final durability close to to that of standard polycarbonate diols.

Thanks to their optimal properties, the use of low viscosity polycarbonate diols allows for the production of high-performance and long-lasting coatings, adhesives, and elastomers, overcoming handling and viscosity limitations, and offering durability performance comparable to that of standard polycarbonate diols. This innovation represents a step forward in the search for solutions that drive excellence in our products and processes.
