WebOct 14, 2024 · The viscosity and density of the resins was measured at 25 °C using a Ford Cup and hydrometer, respectively. To determine the gel time, 5 g of the resin were introduced into a dry glass beaker. The beaker was then immersed into boiling water and the time until hardening was measured. WebOverall, the viscosity values obtained are between 330 and 790 (mPas), and most of the prepared resins have viscosities within the range of 275to425 (mPas) suitable for use in plywood manufacture (Alonso et al. 2004).
