Product overview
CRAYVALLAC® LA-150 is a new pourable liquid rheology modifier supplied in Dimethylsulfoxide (DMSO) for post addition to solvent based systems.CRAYVALLAC® LA-150 is a post-addition rheology modifier composed of a modified urea dissolved in DMSO. When added to the final system, the DMSO is diluted and the modified urea crystallizes out as very fine fibres which build into a three-dimensional interacting network. It is this network that gives rise to the system’s shear thinning rheology and time dependent viscosity recovery. The result is excellent control of sedimentation combined with ease of application. Immediately following application, where low shear conditions again predominate, the system’s viscosity undergoes a time dependent recovery as the network re-establishes itself. This time dependency is known as thixotropy and enables the final system to attain very good levelling.
