CRAYVALLAC LA-100

CRAYVALLAC LA-100 is a modified urea dissolved in N-methylpyrrolidone. This new pourable liquid rheology modifier is suitable for post-addition to solvent-based coatings. CRAYVALLAC LA-100 should be added after the pigment dispersion and grind stage when the coating has been thinned to its approximate final high-shear viscosity. Addition during the pigment grind stage, or under other conditions of high shear, will result in a coating with significantly reduced sedimentation and sag characteristics. The performance of CRAYVALLAC LA-100 is very dependent on the solvent-balance of the coating system. The following two bulletins explain how to maximise the performance of CRAYVALLAC LA-100 through solvent-balance optimisation:
