Die coating

Various types of equipment are used commercially to manufacture dispersed pigment concentrates or finished dispersion products used by printing ink, and die coatings and plastics industry. These include kneaders or internal mixers close tolerance mills high speed fluid energy mills ball and pebble mills san, bead, and shot mills.

It is observed that the fibre-matrix adhesion increases, whatever the nature of the epoxy, from the untreated to the oxidized and coated fibers. For instance, in the case of resin II, the increase is 70 to 80% when die coated fiber 3 is used.

A residence time in the reactor of 12-15 seconds sufficiently hardens the resin to allow rerouting die coated wire inside the reactor for longer, total exposure. The dependence of defect count on wire speed and total exposure is shown in Table III.

These additives allow a process to stabilize quickly after a short period of processing or conditioning time (as little as 10 minutes), during which the die coating forms. This relatively short period is potentially several minutes less than the start-up time that would otherwise be required without the additive, for stabilizing the process and eliminating melt fracture To be effective, the aid must be added at a threshold concentration level, typically at around 500-1000 ppm. However, as discussed in Case 12.1, new additive packages allow reduced concentrations to be used [12-11, 12-13].
