The Low Down on DRAs
Drift Reduction Agents (DRAs) come as polymers, invert emulsions, vegetable polymers, and emulsifiers. Polymer types are thickeners and are susceptible to pump shear. Invert emulsions are tricky and can be unreliable. Vegetable polymers are thickeners but not as thick as other polymers, and are more resistant to pump shear. Emulsion...
