  • Publication number: 20090255594
    Abstract: An apparatus (1) for the application of a composition curable by irradiation to a fastener (2) having: a conveyor (3) for conveying fasteners to an application station (5); an application station (10) comprising an applicator from which the composition is dispensed. The conveyor rotates the fasteners past the applicator for application of composition. The same or another conveyor (8) conveys the fasteners to an irradiation station (10) and rotates the fasteners for irradiation thereof. The irradiation station irradiates and thus cures the composition applied to each fastener.

  • Patent number: 5116558
    Abstract: A method of forming a gasket in situ between two components which includes injecting into a groove in at least one of said components a curable composition including:one or more free-radical polymerizable vinyl esters, and ingredients of a rapid free-radical cure system therefor,the cure system being inactivated prior to injection of the composition,and the composition having a viscosity at 25.degree. C. in the range from 200 to 500,000 mPas;and permitting the composition to cure.The composition can be a two part composition wherein the first part contains a prepolymer, monomer and activator and the second part a prepolymer, monomer and activator. The composition can also include two expansion reactants, each in a separate part of the composition prior to injection, which react to form a gas in situ in the composition. The gasketing composition is suitable for use in engines and other machines e.g. in industrial manufacturing plants.

  • Patent number: 4497916
    Abstract: An improved sealing or adhesive composition comprising a stable slurry of solid meltable wax-like particles dispersed in a liquid adhesive or sealant composition, such as an anaerobic adhesive of sealant, which may be caused to cure at a time later than the time of application. The composition may be applied to threaded bolts or other articles by pumping the slurry through a heated applicator head to dispense homogeneous liquid on the article which hardens on cooling to a non-mobile setable coating.
