  We investigate a model for colloidal network formation using Brownian
Dynamics computer simulations. Hysteretic springs establish transient bonds
between particles with repulsive core. If a bonded pair is separated by a
cutoff distance, the spring vanishes and reappears only if the two particles
contact each other. We present results for the the bond lifetime distribution
and investigate the properties of the van Hove dynamical two-body correlation
function. The model displays crossover from fluid-like dynamics, via transient
network formation, to arrested quasi-static network behavior.
