wetting agent
- 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.
