Get a consistent, reliable kick every time with our MEKP Catalyst. This concentrated curing agent is the essential catalyst for all polyester resins, including laminating, sanding, and gloss resins.

Because MEKP is temperature-sensitive, successful glassing depends on adjusting your ratios to your environment. While the standard baseline is 70°F, you can fine-tune your "pot life" by adding slightly more catalyst in colder conditions or reducing it when the shop heats up to prevent the resin from kicking too fast.

Mixing Guidelines (at 70°F):

Pint (16 oz) Resin: Requires 1/4 oz. Catalyst

Quart (32 oz) Resin: Requires 1/2 oz. Catalyst

Gallon (128 oz) Resin: Requires 2 oz. Catalyst

Key Features:

High Concentration: Industrial-grade peroxide for consistent curing.

Universal Compatibility: Works with Silmar, Reichhold, and all standard surfboard polyester resins.

Precision Control: Allows you to manage your work time based on your local climate.

Safety Note: MEKP is a strong oxidizer. Always wear eye protection and gloves when handling. Avoid contact with skin and eyes, and store in a cool, dark place away from direct sunlight.
