Definição1
A wetting agent is defined as a chemical compound that, when added to water in proper quantities, materially reduces its surface tension, increases its penetrating and spreading abilities, and might also provide emulsification and foaming characteristics.

Nota adicional1
Under certain fire situations “wetting agents” may be appropriate.
Nota adicional2
These agents should be discharged through an in-line proportioning system to a handline so as not to contaminate the vehicles primary foam distribution system. These agents should not be mixed in any primary agent tanks.
