MEKP Catalyst (Methyl Ethyl Ketone Peroxide)

Description:

MEKP is a clear initiator essential for the curing of polyester resins and gelcoats. It is often called a catalyst but in technical terms, it is actually an initiator. Commonly used in boat building, fiberglass projects, and other resin applications, it ensures a consistent and rapid cure.

Key Features:

• Consistent Cure: Provides a uniform hardening process for polyester resins.
• Versatile Use: Suitable for a range of applications including boat building, fiberglass molding, and more.
• Clear Formulation: Does not alter the color or appearance of the resin.

Specifications:

Appearance:

Clear liquid

Shelf Life:

6 months when stored in a cool, dry place

Reactivity Rate:

Balanced for optimal working time and set time

Usage Instructions:

1. Ensure the surface is clean and dry before application.
2. Measure the required amount of MEKP as per the resin manufacturer’s instructions.
3. Mix thoroughly with the resin until fully blended.
4. Apply as needed and allow to cure as directed.
5. Typically, you can increase the amount of MEKP used up to +- 50% to adjust cure time.

Safety Information:

• Wear protective gloves and eyewear when handling.
• Use in a well-ventilated area.
• Avoid contact with skin and eyes.
• In case of contact, rinse immediately with plenty of water and seek medical advice.
• Keep out of reach of children.

Storage:

Store in a cool, dry place away from direct sunlight. Ensure the cap is tightly sealed after use to prevent contamination.

Note: Always refer to the manufacturer’s guidelines for the specific resin you are using to determine the correct MEKP ratio.

More information on Catalysts and Initiators:

MEKP (Methyl Ethyl Ketone Peroxide) is both an initiator and a catalyst. In the context of polymer chemistry, especially for unsaturated polyester resins, MEKP acts as an initiator to start the polymerization reaction. In general terminology, it’s often referred to as a catalyst because it speeds up the reaction without being consumed in the process. However, in the specific context of polyester resin curing, it’s more accurate to call it an initiator.
