WebSep 1, 2024 · Gelation is one of the most important phenomena that occur during the cure reaction of thermoset polymers. It is an irreversible reaction in which the polymer, initially a viscous liquid, transforms into an elastic gel, acquiring elastic properties that are not present in the viscous state (pre-gel). At this point, known as gel point (GP), the ...
Webreflected in the flow point (Table 2). Wall paint 1 (blue curve) shows higher values for G′ and G″ as well as a higher flow point. This means that more force has to be expended to make this sample flow than for wall paint 2. In addition, it can be seen that wall paint 2 undergoes a much stronger structure collapse than wall paint 1, which is simplon chenoa bosch cx mit riemenantriebWebJan 10, 2024 · As rheology is an area that is concerned with how liquids flow, the viscosity of a fluid plays a significant role in the rheological properties that a fluid possesses.
