Urethane acrylate coating on coagulated polyurethane surfaces by UV radiation

In this thesis, the aim is to develop some formulations with urethane prepolymer toimprove mechanical properties of coagulated polyurethane surfaces with desiredproperties. Like most oligomers, the urethane acrylates are typically high in molecularweight and viscosity. Diluents, particularly multifunctional acrylate monomers, are usedto reduce viscosity to manageable levels and to provide crosslinking. The formulatedsolutions are coated on coagulated PU surfaces and cured under UV light. Furthermore,coated cogulated PU surfaces are tested for their physical and mechanical properties.Keywords: Photopolymerization, Urethane Acrylate, UV, Coating, MechanicalProperties
