The viscosity ofliquid adhesives decreases with increasing temperature until pol5mierization begins to occur, then increases. The viscosities of epoxies are reported to decrease 20% to as much as 80% for a 10°C rise in temperature above room temperature, Figure2.4 shows this viseosityreduetion as...

The generation ofliquid-liquid dispersions, commonly used as emulsions, has many commonalities with the generation of bubble suspensions, but differences also exist, due to the different ranges of interfacial tensions, viscosities and densities between the two systems. Surfactants are often introduced to facilitate dispersion formation and reduce coalescence.
