Features & Benefits

CASE Ingredients Features
Product Benefits
  • CRAYVALLAC® LA-350 is a modified urea dissolved in DMSO and is a pourable liquid rheology modifier for post addition to water-based coatings such as water- dilutable alkyds and acrylic emulsions.
  • CRAYVALLAC® LA-350 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.
  • Due to the multitude of formulations, processing methods and application conditions used in the field, we strongly recommend that all products containing CRAYVALLAC® LA-350 be tested thoroughly to ensure their suitability for their intended end use.
Performance Benefits
  • Post addition pourable liquid
  • Temperature independent activation
  • pH independent
  • Imparts shear thinning rheology with thixotropic viscosity recovery
  • Good anti-sag properties
  • Good recoatability
