The embodiments herein relate to a composition of a fluorinated polyurethane acrylate resin and a polyurethane acrylate resin, which, upon curing, is durable and has anti-stain and anti-scratch properties. The preparation of the composition is conducted with a one-pot multicomponent synthesis process, wherein multiple components are put together to carry out reactions simultaneously. The process is especially suitable for industrial scale production, and open for adding additive components to further adjust the performance of the prepared composition. The embodiments herein also relate to oligomers prepared in the synthesis process, as well as the use of the composition or oligomer to form a coating onto a substrate.

Hybrid spray foams utilize a urethane reactant, a crosslinker, and an (optional) epoxy and/or acrylic resin along with a blowing agent and rheology modifier to produce a quick-setting foam that remains in place until the foam forms and cures. The urethane reactant may be formed as an adduct with or without the use of isocyanate chemistry. In some embodiments, the polyurethane oligomer is made by reacting cyclocarbonates and di- or polyamines, while in other embodiments the polyurethane backbone employs the use of commercially available capped or blocked urethane oligomers made by any method. The oligomers contain reactive groups, typically at the oligomer ends, that crosslink with crosslinkers or with acrylic or epoxy resins to form hybrid polyurethane foams. Foams may also contain a plasticizer, and/or a surfactant as well as other optional additives. Methods of making such foams are also provided.
