Clear Catalyst Norox MEKP 925 for Gelcoat and Polyester Resins

Clear Catalyst Norox MEKP 925


Offered in multiple sizes, Norox® MEKP 925 is a methyl ethyl ketone peroxide composition formulated to be an excellent cure initiator for both unsaturated polyester resins and vinyl ester resins. With most unsaturated polyesters it gives longer gel and gel to cure times but with a higher peak exotherm than Norox® MEKP 9, particularly in thick sections.


MEKP 925


Norox® MEKP 925 has a high MEKP dimer content that gives excellent performance in most vinyl ester resins. Norox® MEKP 925 also performs well when used with general purpose ortho and isophthalic resins. Norox® MEKP 925 should be considered when an initiator is desired for use with most all resin types. 

This product is offered in multiple sizes. Depending on the size, a hazmat shipping fee may be required to ship.

    “I love fiberglass coatings. They have great products and excellent advice. I'm trying to open a boat repair shop in St . Mary's, GA and my supply WILL come from fiberglass coatings. When I lived in the Fl. Keys for 36 years and worked for a towing and salvage Co for 15 years all our supplies came from Fiberglass coatings. Great service and never were disappointed. Keep up the great job everyone.”

    “Been working on a skiff project and using all FGCI products. They came highly recommended by my friends who are boat builders. It is the highest quality resins, glass, and gelcoat for the money. They made it really easy for a newer person to boat building. The customer service is phenomenal and they are always knowledgeable and ready to help with any questions I had.”
