Abstract
A fast gelling method of formulating and applying a curable butyl rubber sealant composition which composition is cured using a quinoid curing agent and a free radical cross-linking activator. The curing agent and a first portion of the activator are added to the sealant components to produce a base component. If the amount of activator in the first portion is chosen correctly, the base component remains ungelled until the remainder of the activator is added, at which time a very rapid gel takes place. This method is particularly useful where the sealant is a tire sealant and is to be sprayed onto the inner surface of a tire.
