SPECIFIC MIXING INSTRUCTIONS (Inline Mixing) • Store the resin in the recommended temperature range as per the resin manufacturer’s guidelines. Before mixing any chemicals measure and record the resin temperature and the time. • Start resin pump and circulate resin within the bulk storage system. • Weigh the calculated amount of each catalyst. Be aware that the Perkadox 16 is a powder and must first be dissolved before being introduced into the resin. Styrene monomer has been found as a suitable solvent to accomplish this task. In order to fully dissolve the Perkadox 16, use styrene at a 1:1 ratio by weight of Perkadox 16. • Mix the catalysts and dye in an appropriate container until thoroughly mixed. For the catalyzation, add the chemicals separately in the following sequential order: • Styrene Monomer / Trigonox KSM or other secondary catalyst • Perkadox 16 / or other primary catalyst • 1 cc of dye per pound of Perkadox 16 After the Perkadox 16/styrene monomer/Trigonox KSM solution has been mixed thoroughly, filter the solution through an appropriate screen and pour into the catalyst hopper. Start the catalyst pump in the re-circulation mode. Take the time vs weight calibration sample as per manufacture’s directions. Zero the resin totalizer. Set the catalyzation rate (ml / min) as per manufacturer’s recommendations). Turn switch from Re-circulation to Dispense. Take a resin sample every 500 pounds for a gel test (see RESIN SAMPLING & GEL TIME TESTING). SPECIFIC MIXING INSTRUCTIONS (Drum Mixing) • Store the resin in the recommended temperature range as per the resin manufacturer’s guidelines. Before mixing any chemicals, measure and record the resin temperature and the time for that drum. • Set the mixing blade in the drum to a depth of approximately three-fourths (¾) of the way to the bottom. Adjust the rotational speed of the mixing shaft to establish a circular vortex in the resin that extends approximately one-fifth (1/5) of the way down the shaft from the top of the resin. Do not allow the surface of the mixing blade to be exposed by generating a strong vortex, because this will entrain air bubbles into the resin. If the maximum speed does not allow for an adequate vortex then the blade diameter should be increased. • Weigh the calculated amount of each catalyst. Be aware that the Perkadox 16 is a powder and must first be dissolved before being introduced into the resin. Styrene monomer has been found as a suitable solvent to accomplish this task.
