Abstract

A pack comprising: a dispenser for anaerobically curable composition; and anaerobically curable composition held within the dispenser. The dispenser has (a) a reservoir in which anaerobically curable composition is held, the reservoir having an outlet through which the anaerobically curable composition can be dispensed; (b) a dispensing pump for pumping the anaerobically curable composition from the reservoir out through the outlet. The reservoir and pump together form an airless pump assembly. An applicator with an applicator surface, for example a roller, is in communication with the outlet, the applicator for applying to a substrate the anaerobically curable composition that is dispensed by the pump from the reservoir out through the outlet. The pack provides a convenient way of forming of applying anaerobically curable composition in a thin even layer.
