If you’re working with composites, chances are you’ve come across the name BUTANOX®. Whether in marine, construction, or automotive applications, choosing the right curing agent is critical for achieving the strength, durability, and finish your products demand. That’s where BUTANOX comes in — a trusted solution in resin curing that helps you turn liquid formulations into high-performance materials.
What Exactly is BUTANOX?
BUTANOX refers to a range of methyl ethyl ketone peroxide (MEKP) formulations designed to initiate the curing (polymerization) of liquid resins into solid composites. Acting as a free-radical initiator, it starts the crosslinking process that transforms unsaturated polyester resins (UPR) and vinyl ester resins (VER) into durable, long-lasting products.
Compared to other peroxides, BUTANOX stands out for its safety, predictable reactivity, and consistent performance under a wide range of processing conditions.
Key Features of BUTANOX
- Controlled Reactivity – Ensures predictable curing speeds and reduces risks of under- or over-curing.
- High Purity – Provides consistent results in demanding applications.
- Safety-Oriented – Stabilized formulations minimize handling and storage risks.
- Versatility – Works with both hand lay-up and automated composite processes.
Applications of BUTANOX
You’ll find BUTANOX widely used across industries:
- Marine & Boatbuilding – Strong, durable fiberglass hulls.
- Construction – Panels, sanitary ware, and reinforcement structures.
- Transportation – Lightweight yet robust automotive and aerospace parts.
- Industrial Equipment – Chemical-resistant tanks, pipes, and profiles.
Why BUTANOX Matters for You
