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 allow it to come in contact with skin. It will cause a chemical burn. Goggles should be worn when mixing. The MEKP we sell is diluted, but still hazardous. Do not think that it is less dangerous. Wear protective goggles when mixing resin and hardener together. Wear long sleeve clothing, including face protection if there is any risk of the mekp splashing. Keep away from children.
Splashing
Any MEKP splashing on the skin should be immediately cleaned off and rinsed with water. You should be wearing full protective clothing, face mask, and goggles if there is any risk of inadvertent contact. Avoid using the MEKP in situations, where splashing may occur.
Mixing Table
Small amounts of catalyst are required for Polyester Resin hardening. See below for approximate values.
| Catalyst & Resin Mixing Table | |||||
|---|---|---|---|---|---|
| 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.
