Thermoset pu

WebbNew lignin-based thermoset polyurethane (PU) coatings with high lignin content are presented in this work.

Webb1 jan. 2013 · Polyurethane (PU) resin system has better mechanical properties and higher impact strength compared to conventional polyester and vinyl ester resin systems.

In materials science, a thermosetting polymer, often called a thermoset, is a polymer that is obtained by irreversibly hardening ("curing") a soft solid or viscous liquid prepolymer (resin). Curing is induced by heat or suitable radiation and may be promoted by high pressure, or mixing with a catalyst. Heat is not necessarily applied externally, but is often generated by the reaction of the resin with a curi…
