Polyurethane coatings are available in either single or two-component formulations. Both options provide excellent humidity resistance and far greater chemical resistance than acrylic coatings. Single component polyurethanes, while easy-to-apply and enjoy long pot life, sometimes require long curing regimen...
polyurethane or epoxy. Since pure polyureas are formed by the reaction of only two materials, their potential properties are restricted by the limited flexibility in their formulation. So while a more complex system, the properties of hybrid polyurea formulations are more modular, and can be ...
This has been primarily due to the unique characteristics of the technology, both in processing and performance. However; over the years there has been a melding of the various technologies, and many have now classified or implied that polyureas are the same as urethane and/or urethane/urea ...
