Flake-filled laminates

As with trapping, the delivery mechanisms for the pheromones are important. They must be able to provide a nominated dose over an extended period, often under adverse weather conditions. Thus, various slow-release methods have been devised for field use and incorporated into the delivery systems. These have involved the use of hollow fibres as reservoirs which can be applied aerially on to the canopy of plants twisted rope formulations consisting of wire-based sealed polyethylene tubes filled with disruptant that are twisted around the base of plants other polyethylene or rubber tube or polymeric ampullae dispensers, multilayered laminates of acrylic polymer flakes, resin-treated filter paper and micro-encapsulated formulations. 

Composite kam- pa-z3t, kom-, esp British kam-po-zit [L compositus, pp of compo-nere] (1563) adj. (1) An article or substance made up of two or more distinct phases of different substances. In the plastics industry the term applies broadly to structures of reinforcing members dispersed phase) incorporated in compatible resinous binders continuous phase). Such composites are subdivided into classes on the basis of the reinforcing constituents laminate, particulate (the dispersed phase consists of unlayered fibers) flake (flat flakes forming the dispersed phase) and skeletal (composed of a continuous skeletal matrix filled by a resin). (2) Hard or soft constructions in which the fibers themselves are consolidated to form structures rather than being formed into yarns. Rigidity of these constructions is controlled by the density, the modulus of the load-bearing fibers, and the fraction of fusible... 

An unacceierated, low viscosity, highly cross-linked novolac epoxy vinyl ester offering superior oxidation resistance, excellent solvent and acid resistance and suitable for hand-lay, spray/projection lamination and for flake glass, filled linings and coating compounds. Hetron 980 and 980/35 are recommended when increased toughness is required at less critical operating temperatures.)...
