Catalyst Norox MEKP 925

Adjust the catalyst level to slow down or speed up gel time. Cooler temperatures may require a higher percentage of catalyst than warmer temperature conditions.
Proper catalyzation is imperative for proper cure when using polyester. The higher the percentage of hardener, the faster the product will dry. Do not over-catalyze or under-catalyze. Do not add less than 1% catalyst or greater than 3% catalyst for best results. We recommend a trial to determine final catalyst ratio for your project.
