Abstract

Un dispositivo generador para producir, en forma de vapor o de gas, un reactivo o catalizador para un aglutinante orgánico endurecible, caracterizado por un recipiente que contiene dicho reactivo o catalizador en forma líquida y medios para reducir la presión en dicho recipiente por debajo de la presión de vapor del reactivo o catalizador, por lo que la evaporación es acelerada.
