AbstractThe effects of weathering agents on the mechanical properties of paint films in a film-substrate system have been considered for study by the vibrating-reed method. The method used by Van Hoorn and Bruin is modified, chiefly as to reed design, in order to study the effects of fadeometer radiation on the dynamic modulus of elasticity of paint films attached to stainless steel substrates. The measurements disclose differences in modulus changes among films and two effects of radiation which are attributed to gross thermal and photo-radiation effects. As such, if modulus changes are comparable or greater, this method can probably be used to study the effects of other weathering agents, especially on a long-term basis.
