Liquid urea rheology modifier for post-addition to waterborne systems
Product overview
CRAYVALLAC® LA-377 is a modified urea dissolved in DMSO. CRAYVALLAC® LA-377 is a pourable liquid rheology modifier for post addition to water-based coatings such as water-dilutable alkyds and acrylic emulsions. It was developed to ensure particular suitability for metal coating as its formula is lithium chloride-free. CRAYVALLAC® LA-377 should be added to the coating as a slow stream under low to medium shear conditions to ensure sufficient dispersion. Although efficient stirring is required to ensure homogeneity, elevated temperatures are not required for activation and the use of excessive shear should be avoided.
