This type of thickener is based on modified ureas dissolved in N-methylpyrrolidone, which are insoluble in common coating solvents. Upon careful incorporation into coating systems, the controlled precipitation of additive forms very fine, needle-like microcrystals. The crystals form a three-dimensional lattice structure via hydrogen bonding, which results in thixotropic behavior of the system.
