Butanox® is the world’s leading brand of methyl ethyl ketone peroxides (MEKP). These products are used for the curing of thermoset resins and coatings.

Butanox is an essential ingredient in curing composite materials like pipes, wind turbine blades, composite bridges, racing yachts, chemical storage tanks and many other valuable end products. Look around and chances are you'll see AkzoNobel’s influence.

The world’s leading composite manufacturers and users of unsaturated polyester resins (UP) rely on Butanox. Why? Because Butanox is the benchmark in the glass fiber reinforced plastics (GRP) industry. It is recognized as the best and most reliably used MEKP across the entire range of applications and reactivities of commercially available UP resins and vinyl ester (VE) resins. Butanox is also the most stable MEKP available on the market, with continuous high quality and a guaranteed low water content.

Butanox M-50 is the leading MEKP in our portfolio. It contains no polar ingredients, such as glycols and alcohols, and prevents osmosis in boat building and gelcoat curing.

Butanox Vanishing Red

For more than a half century, Butanox* has earned an industry-wide reputation for outstanding product quality, safety and innovation. One example is our Vanishing Red (VR) series of MEKPs. These unique materials leave no red color in the final resin, while providing all of the benefits of normal dyed peroxides. The VR MEKPs allow for monitoring and securing peroxide flow in spray equipment, yet the red color disappears during the curing process leaving the end product colorless.

If you’re looking for reliable methyl ethyl ketone peroxides, then Butanox is the brand of choice when high-quality curing must be guaranteed.

*In North America our MEKPs are offered under the Cadox® trademark.
