Thixotropic rheology modifying agent compositions
Solvents that are suitable for use with polyurethane-polyurea based rheology modifying agents of the type which, in the past, have generally been formulated as solids or viscous liquids. The present solvents enable the rheology modifying agents to be prepared and formulated in a liquid or solution form more suited to prepare coating formulations that include polyurethane-polyurea based rheology modifying agents. The present solvents are N-alkyl substituted caprolactams, including N-methyl caprolactam, N-ethyl caprolactam, N-butyl caprolactam, and mixtures thereof, which are aprotic, non-toxic, have good solvency for polar groups such as those found in polyurethanes and polyureas, are thermally stable, and have high boiling points and low vapor pressure.
