NOROX KP-9 is a general purpose MEKP and is the workhorse of the United Initiators line. NOROX KP-9 gives consistent room temperature performance with both resins and gelcoats. A reliable product of remarkable purity, NOROX KP-9 assures quality in almost every system. Suitable applications are: Hand lay-up, spray-up, RTM, continuous laminating, centrifugal casting, filament winding, polyester
concrete and vacuum infusion. A single MEKP Initiator formulation cannot provide optimum results in all Resin systems. Evaluation of each MEKP in each resin intended for use is absolutely essential before full-scale manufacturing is attempted.
A reactivity test with an unsaturated Polyester Resin gave the following results:
| Resin: | Orthophthalic polyester | Temperature: | 25°C |
| Initiator %: | 1.5 | 0,5% (1% cobalt) |
| Initiator | Gel time Min | Time to peak min | Peak exotherm temp °C |
| NOROX KP-9 | 25 | 61 | 88 |
| NOROX KP-100 | 18 | 48 | 106 |
| NOROX SG-10 | 13 | 44 | 101 |
