Abstract: This invention relates to (meth)acrylate based polymerizable compositions and adhesive systems prepared therefrom, which include an initiator system comprising a complex of an organoborane with a complexing agent, an aziridine-containing compound, and a carrier material with which the initiator system is unreactive and which renders the composition having a flash point above 140° F. The inventive compositions desirably have a flash point above 200° F., for each of the parts of the adhesive system. To achieve the physical properties of the inventive compositions and adhesive systems, it is desirable for the carrier material to have such flash points; however, provided that in their entirety the inventive compositions and adhesive systems have such flash points, it is not necessary for the carrier material itself to have such flash points. The inventive compositions and adhesive systems also include a package for controlling the rate of cure and indicating the extent of cure.

Abstract: The invention provides a device and method for dispensing fluid materials from a product reservoir onto a substrate. The device includes at least one dispensing nozzle having at least one inner conduit leading to an exit port and adaptable to be in fluid communication with a supply source for the fluid dispensable material. The nozzle further comprises an end portion defining the exit port such that a ribbon of fluid dispensable material can be applied to the substrate. The nozzle is mountable on means that effect substantially perpendicular free movement of the nozzle relative to the substrate, such that the end portion of the nozzle maintains contact with the fluid material applied to the substrate. During dispensing, movement towards the substrate is effected by an applied force and movement away from the substrate is effected by a thrust exerted by the dispensed fluid material against said end portion of the nozzle and the dispensable material in the exit port.
