Methyl Ethyl Ketone Peroxide (MEKP) is a hardener or catalyst used for Polyester Resin. It is used in small quantities relative to the resin when mixing.
Safety
MEKP is highly flammable. It is also corrosive. Do not leave exposed to skin for long periods of time. Use caution.
Mixing Table
Small amounts of catalyst are required for Polyester Resin hardening. See below for approximate values.

|---|---|---|---|---|---|
| FOR THIS CONCENTRATION OF CATALYST L-50 OR M-50 | 1 QUART RESIN | 1 GAL. RESIN | 5 GALS. RESIN | 55 GAL. DRUM 475 LBS. | |
| 0.5% RESIN | 4.7 CC 0.2 OZ. | 18.8 CC 0.72 OZ. | 94.0 CC 3.6 CC | 2.5 LBS. 40 OZ. | |
| 1% GELCOAT | 9.4 CC 0.4 OZ. | 37.6 CC 1.44 OZ. | 188 CC 7.2 OZ. | 4.95 LBS. 79 OZ. | |
| 1.5% | 14.1 CC 0.54 OZ. | 56.4 CC 2.2 OZ. | 282.0 CC 10.8 OZ. | 7.4 LBS 119 OZ. | |
| 2% | 18.8 CC 0.72 OZ. | 75.2 CC 2.9 OZ. | 376.0 CC 14.4 OZ. | 9.9 LBS. 158 OZ. | |
Note: These chemical reactions are temperature sensitive. Best results happen between 60°F - 80°F. We recommend you start at 1% for resins. Do NOT go lower than ½% for resin. We recommend you start at 1-1.5% for Gelcoats. Do NOT go lower than 1% for gelcoats.
