Gel point

Upon reaching the gel point is in the course of gelation before a mixture of a gel. With the increasing cross-linking of particles in the gel or the sol-gel process, the gel point is defined mostly by the linkage of the clusters into a macroscopic device, so a continuous chain at the expense of the sol. A further definition option sets the gel point as the point at which storage modulus and loss modulus are equal in magnitude, fixed. A definition about the sudden increase in viscosity is possible. This is, however, difficult to detect, because the process of gelation often extends over very long periods.

A simple definition defines the gel point determined as the point in time at which a sample is not deformed or flows.
