Gel Point Determination of TEOS-Based Polymeric Materials with Application on Conservation of Cultural Heritage Buildings

Figure 3

Elastic (solid symbols) and viscous (hollow symbols) moduli measured at frequencies of 1 rad/s (black circles), 10 rad/s (red squares), and 100 rad/s (green triangles) as a function of time. Lines are guides to the eye. Dashed vertical lines indicate the time interval where the crossover of G’-G’’ occurs.
