Abstract: Most sprayable polymers are known to undergo wicking into soil due to their low viscosity and have poor efficacy as barriers to reduce soil water evaporation. To minimize wicking, we investigated four different viscosity modifiers (VMs); gelatine (GL), sodium alginate (ALG), xanthan gum (XAN) and polyacrylamide (PAM) in our waterborne polymer formulation (PF). The viscosity modifiers were assessed based on their water solubility, miscibility with the PF and their effect on sprayability.
