ABSTRACT:
A catalyst system for promoting the room temperature of isocyatic cured polyurethane based propellants. The system is composed of a metal catalyst; a chelating agent or an acid as a suppressor component; and zinc oxide as a scavenger component. The suppressor inactivates the catalyst, thus providing the necessary potlife, while the scavenger slowly consumes the suppressor, thus restoring the activity of the catalyst, which then promotes an effective cure.
