What is a critical characteristic of an abrasive spray material?

An abrasive spray material is characterized by its physical properties that can significantly impact handling and application methods. The requirement for special equipment is crucial due to the nature of abrasive materials, which can cause wear and damage to standard application equipment. These materials often contain particles that can be destructive to pumps, nozzles, and hoses that are not designed to withstand such stress.

In contrast, other characteristics such as low viscosity or noncorrosiveness, while important in their respective contexts, do not define the abrasive nature of a spray material. Additionally, while some abrasive materials might be used in large volumes, this is not a defining characteristic since volume usage can vary widely depending on the specific application and formulation. Therefore, the need for specialized handling equipment is the key identification factor for abrasive spray materials.
