Dynamic viscosity of pdms
WebSecond, the capability of the rheometer was verified using polydimethylsiloxane (PDMS), which is a typical viscoelastic fluid. Viscosity and viscoelastic properties, such as storage/loss modulus, and complex viscosity, were evaluated. Thirdly, the effects of the dissolved CO2 on the rheological properties of PDMS were investigated. WebJan 1, 2024 · The results indicate that the mechanical properties of the coating formed by the crosslinking reaction with a high viscosity of PDMS resin are better. Despite the different viscosity of PDMS resin, the coating has the best mechanical properties, when the mole ratio of PDMS to TEOS is 1: 18.24.
